I am trying to use WAMP on Windows 7, my WAMP is online, but when I open localhost I get the welcome page of IIS 7.5, although I have uninstalled IIS 7.5 from my PC!

Apache server test says that port 80 is used my Microsoft-HTTPAPI/2.0

MS Visual Studio 2010 was uninstalled a short while ago as well.

Can&#39;t use WAMP , port 80 is used by IIS 7.5

I&#39;m trying to enable CORS support in my WebAPI project, and if I enable Anonymous Authentication then everything works fine, but with Windows Auth + disabled anonymous authentication, the OPTIONS request sent always returns a 401 unauthorized response. The site requesting it is on the DOMAIN so should be able to make the call, is there any way to get around the issue without disabling Windows Authentication?

In my Win 7 development machine, and in order to use SQL Express instance instead of the localDB installed by default. I unchecked &quot;Use IIS Express&quot; in my MVC 4 project properties page (Web tab), then I got the following error:

**ASP.NET 4.5 has not been registered on the Web server. You need to manually configure your Web server for ASP.NET 4.5 in order for your site to run correctly.**

I verified that ASP.NET is activated within the IIS features.

How to increase request timeout in IIS?

This is driving the whole team crazy. There must be some simple mis-configured part of IIS or our Web Server, but every time we try to run out ASP.NET Web Application on IIS 7.5 we get the following error...

Here&#39;s the error in full:

    HTTP Error 500.19 - Internal Server Error

    The requested page cannot be accessed because the related configuration  
    data for the page is invalid.

The machine is running **Windows Server 2008 R2**. We&#39;re developing our Web Application using **Visual Studio 2008**. 

According to Microsoft the code 8007000d means there&#39;s a syntax error in our web.config -- except the project builds and runs fine locally. Looking at the web.config in XML Notepad doesn&#39;t bring up any syntax errors, either. I&#39;m assuming it must be some sort of poor configuration on my part...?

Does anyone know where I might find further information about the error? Nothing is showing in EventViewer, either :(

Not sure what else would be helpful to mention...

Assistance is greatly appreciated. Thanks!

**UPDATES! - POSTED WEB.CONFIG BELOW**

Ok, since I posted the original question above, I&#39;ve tracked down the precise lines in the **web.config** that were causing the error.

Here are the lines (they appear between `&lt;System.webServer&gt;` tags)...

		&lt;httpHandlers&gt;
			&lt;remove verb=&quot;*&quot; path=&quot;*.asmx&quot;/&gt;
			&lt;add verb=&quot;*&quot; path=&quot;*.asmx&quot; validate=&quot;false&quot; type=&quot;System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56&quot;/&gt;
		&lt;/httpHandlers&gt;

Note: If I delete the lines *between* the `&lt;httpHandlers&gt;` I STILL get the error. I literally have to delete `&lt;httpHandlers&gt;` (and the lines inbetween) to stop getting the above error.

Once I&#39;ve done this I get a *new* 500.19 error, however. Thankfully, this time IIS actually tells me which bit of the web.config is causing a problem...

		&lt;handlers&gt;
			&lt;remove name=&quot;WebServiceHandlerFactory-Integrated&quot;/&gt;
			&lt;add verb=&quot;*&quot; path=&quot;*.asmx&quot; validate=&quot;false&quot; type=&quot;System.Web.Script.Services.ScriptHandlerFactory,System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56&quot;/&gt;
			&lt;add name=&quot;ScriptHandlerFactoryAppServices&quot; verb=&quot;*&quot; path=&quot;*_AppService.axd&quot; preCondition=&quot;integratedMode&quot; type=&quot;System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56&quot;/&gt;
			&lt;add name=&quot;ScriptResource&quot; preCondition=&quot;integratedMode&quot; verb=&quot;GET,HEAD&quot; path=&quot;ScriptResource.axd&quot; type=&quot;System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56&quot;/&gt;
		&lt;/handlers&gt;

Looking at these lines it&#39;s clear the problem has migrated further within the same `&lt;system.webServer&gt;` tag to the `&lt;handlers&gt;` tag.

The new error is also more explicit and specifically complains that it doesn&#39;t recognize the attribute &quot;validate&quot; (as seen on the third line above). Removing this attribute then makes it complain that the same line doesn&#39;t have the required &quot;name&quot; attribute. Adding this attribute then brings up **ASP.NET** error...

&gt; *Could not load file or assembly
&gt; &#39;System.web.Extensions,
&gt; Version=1.0.61025.0, Culture=neutral,
&gt; PublicKeyToken=f2cb5667dc123a56&#39; or
&gt; one of its dependencies. The system
&gt; cannot find the file specified.*

Obviously I think these new errors have just arisen from me deleting the **`&lt;httpHandlers&gt;`** tags in the first place -- they&#39;re obviously needed by the application -- so the question remains: Why would these tags kick up an error in IIS in the first place???

Do I need to install something to IIS to make it work with them?

Thanks again for any help.

Web Application Problems (web.config errors) HTTP 500.19 with IIS7.5 and ASP.NET v2

IIS has an annoying feature for low traffic websites where it recycles unused worker processes, causing the first user to the site after some time to get an extremely long delay (30+ seconds).

I&#39;ve been looking for a solution to the problem and I&#39;ve found these potential solutions.

A. [Use the Application Initialization plugin][1]

B. [Use Auto-Start with .NET 4][2]

C. [Disable the idle-timeout (under IIS Reset)][3]

D. [Precompile the site][4]

I&#39;m wondering which of these is preferred, and more importantly, why are there so many solutions to the same problem? (My guess is they aren&#39;t, and I&#39;m just not understanding something correctly).

**Edit**

Performing **C** seems to be enough to keep my site warmed up, but I&#39;ve discovered that the real root of my site&#39;s slowness has to do with Entity Framework, which I can&#39;t seem to figure out why it&#39;s going cold. See [this][5] question, which &lt;s&gt;unfortunately hasn&#39;t been answered yet&lt;/s&gt; has been answered!

I eventually just had to make a [warm up script](http://social.technet.microsoft.com/wiki/contents/articles/4641.write-an-iis-warm-up-script-for-a-sharepoint-intranet-site-en-us.aspx) to hit my site occasionally to make sure it stayed speedy.

Fixing slow initial load for IIS

I&#39;ve just tried to deploy my first web application to IIS on my Windows 7 Home Premium notebook.  After creating the application, I had to change to the Classic App Pool, then set that pool for framework 4.0.  Now I get the following error:

&gt; HTTP Error 404.17 - Not Found The requested content appears to be
&gt; script and will not be served by the static file handler.

The requested URL is *http://localhost:80/pvmms/default.aspx*

I&#39;m afraid extensive Googling has yielded nothing clear or definite enough for me to work with and as usual I&#39;ve turned to the experts.

**EDIT:**
I suspect this is because there are no framework 4.0 handler mappings for .aspx files.  However, aspnet_regiis even gives my admin user the finger and says I need admin rights to run it.

**EDIT #2:**
I registered all the frameworks (2 &amp; 4, 32 and 64) and all now works.  I found this by manually adding a script map for `.aspx` to aspnet_isapi and voila.  I don&#39;t understand why the installation of the framework doesn&#39;t do this, unless my memory fails me and I only enabled IIS after installing VS.

Script not served by static file handler on IIS7.5

I have an ASP.NET application that accesses private key in a certificate in the certificates store. On Windows Server 2003 I was able to use winhttpcertcfg.exe to give private key access to the NETWORK SERVICE account. How do I give permissions to access a Private Key in a certificate in the certificate store (Local Computer\Personal) on a Windows Server 2008 R2 in an IIS 7.5 website?

I&#39;ve tried giving Full Trust access to &quot;Everyone&quot;, &quot;IIS AppPool\DefaultAppPool&quot;, &quot;IIS_IUSRS&quot;, and everyother security account I could find using the Certificates MMC (Server 2008 R2). However the below code demonstrates that the code does not have access to the Private Key of a certificate that was imported with the private key. The code instead throws and error everytime the private key property is accessed.

How to give ASP.NET access to a private key in a certificate in the certificate store?

At home I have a simple network setup containing 2 machines.

On one machine i have a site hosted with IIS7. Rather than the standard `localhost/index.htm` address I have added an entry in the `HOSTS` file pointing the local IP (127.0.0.1) to this domain - `www.mysite.dev`.

I can access the site with `www.mysite.dev` with no problem.

what I would like to do is be able to view this site from my other machine on the network.

Initially I assumed this could be done with a URL like so 
`MACHINE-NAME/www.mysite.dev`, but the connection always times out. But I can ping `MACHINE-NAME` without problems.

For testing purposes I have disabled the windows firewall on both machines but to no joy.

Like a typical web developer, my hardware/network skills are pretty poor.

Can anyone see where I&#39;m going wrong?

HTTP 404 Page Not Found in Web Api hosted in IIS 7.5

I am trying to set up IIS web services and ASP.NET services on Windows Server 2008 R2. The physical directory was created, but I cannot get it to work. This is a fresh IIS Role installation.

![enter image description here][1]

The server is on a domain, and domain\server$ has read/write/browse access to `C:\inetpub\wwwroot`. Read/write/browse access is also granted to:

 - Administrators
 - Network Services
 - Users
 - IIS_IUSRS
 - IUSR

**What I have tried so far**

 - In the `Edit Virtual Directory -&gt; Connect As` dialog, select Application User (pass through authentication). When I press Test Settings, I get the above error.

 - In the `Edit Virtual Directory -&gt; Connect As` dialog, select Specific user: `IUSR` (no password). When I press Test Settings, I get the following:
![enter image description here][2]


**Other Notes**

Anonymous Authentication is Enabled, and Anonymous user identity is Application pool identity. 

The Application pool configuration looks like this:

In the web browser, `http://localhost` returns an blank page but no error.

Any help would be appreciated.

&quot;Cannot verify access to path (C:\inetpub\wwwroot)&quot;, when adding a virtual directory

I have configured an app pool in IIS 7.5 to recycle when the memory usage goes above a certain level. I have also configured it to log this information.

Where in the event log should I look for this?

I have tried filtering based on the source being all the IIS items, e.g. &#39;IIS-W3SVC-WP&#39;, &#39;IIS-IISManager&#39;, and all the rest, but nothing.

I can see that it is adding in the items from the &#39;IIS-Configuration&#39; log too which I enabled. But still nothing.

How to Find App Pool Recycles in Event Log

I Installed DotNetOpenAuth SDK-3.4.5.10201.vsix and I can&#39;t get it working.
It works locally (when I run as localhost) but when i try to publish it ain&#39;t working. 

The IIS error message I get is 

&gt; Error Summary  
  HTTP Error 500.22 - Internal Server Error  
  An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.

AND

&gt;     Module       ConfigurationValidationModule  
    Notification BeginRequest  
    Handler      StaticFile  
    Error Code   0x80070032  

then there are some suggestions on how to solve the problem:

Things you can try:

&gt; * Migrate the configuration to the
       `system.webServer/modules` section. You
       can do so manually or by using AppCmd
       from the command line - for example,
       `%SystemRoot%\system32\inetsrv\appcmd
       migrate config &quot;Default Web Site/&quot;`.
       Using `AppCmd` to migrate your
       application will enable it to work in
       Integrated mode, and continue to work
       in Classic mode and on previous
       versions of IIS.

&gt; * If you are certain that it is OK to
       ignore this error, it can be disabled
       by setting
       `system.webServer/validation@validateIntegratedModeConfiguration`
       to false.  

&gt; * Alternatively, switch the application
       to a Classic mode application pool -
       for example,
       `%SystemRoot%\system32\inetsrv\appcmd
       set app &quot;Default Web Site/&quot;
       /applicationPool:&quot;Classic .NET
       AppPool&quot;`. Only do this if you are
       unable to migrate your application.  
       (Set &quot;Default Web Site&quot; and &quot;Classic .NET AppPool&quot; to your application path and application pool name)


But the problem is that I don&#39;t have access to the ISS server as I am not the owner of it. Is there any way to solve this?


An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode

Here&#39;s an issue with IIS 7.5 and ASP.NET that I&#39;ve been researching and getting nowhere with. Any help would be greatly appreciated.

My question is: using ASP.NET in IIS 7.5, how does IIS and/or the operating system allow the web application to write to a folder like `C:\dump` when running under full trust? How is it that I don&#39;t have to explicitly add write access for the application pool user (in this case `ApplicationPoolIdentity`)?

This much I know:

 - In IIS 7.5, the default Identity for an Application Pool is `ApplicationPoolIdentity`.
 - `ApplicationPoolIdentity` represents a Windows user account called &quot;IIS APPPOOL\AppPoolName&quot;, which is created when the Application Pool is created, where AppPoolName is the name of the Application Pool.
 - The &quot;IIS APPPOOL\AppPoolName&quot; user is by default a member of the `IIS_IUSRS` group.
 - If you are running under Full Trust, your web application can write to many areas of the file system (excluding folders like `C:\Users`, `C:\Windows`, etc). For example, your application will have access to write to some folders, like, `C:\dump`.
 - By default, the `IIS_IUSRS` group is not given read or write access to `C:\dump` (at least not access that is visible through the &quot;Security&quot; tab in Windows Explorer).
 - If you deny write access to `IIS_IUSRS`, you will get a SecurityException when trying to write to the folder (as expected).

So, taking all of that into account, how is write access granted to the &quot;IIS APPPOOL\AppPoolName&quot; user? The w3wp.exe process runs as this user, so what allows this user to write to a folder it doesn&#39;t seem to have explicit access to?

Please note that I understand this was probably done for the sake of convenience, since it would be a pain to grant a user access to every folder it needs to write to if you are running under Full Trust. If you want to limit this access, you can always run the application under Medium Trust. I am interested in finding out about the way the operating system and/or IIS allows these writes to take place, even though there appears to be no explicit file system access granted.

IIS AppPoolIdentity and file system write access permissions

I use HTTP `PUT` and `DELETE` in my ASP.NET MVC3 application. When I run it in local, every thing works correctly; But when I publish the application to the server, these methods do not work. 

Are there any special settings for enable a web server to support `PUT` and `DELETE` requests? I&#39;m using shared hosting with IIS 7.5.

**UPDATE:**

I enable `PUT` and `DELETE` requests in `IIS manager`. `PUT` command work fine. But `DELETE` still not works. I create requests by `jQuery`:

I&#39;m in this page:

    http://domain.com/dashboard/edit-site/103323/links/

and my ajax call is:

    $.ajax({
        // url: same as page-url,
        cache: false,
        type: &#39;DELETE&#39;,
        data: { linkid: $(link).data(&quot;linkid&quot;) },
        beforeSend: function () {
            // doing something in UI
        },
        complete: function () {
            // doing something in UI
        },
        success: function (data) {
            // doing something in UI
        },
        error: function () {
            // doing something in UI
        }
    });

This will create a request like this:

    Accept: */*
    Content-Type: application/x-www-form-urlencoded; charset=UTF-8
    Origin: http://domain.com
    Referer: http://domain.com/dashboard/edit-site/103323/links/

How do I enable HTTP PUT and DELETE for ASP.NET MVC in IIS?

I have just downloaded and installed IIS express and it all works well running it from the command line:

But how do i configure options for it, is there a standalone windows interface for it like IIS Manager or do you have do do everything manually in the config files? Or do you have to install webmatrix to configure it?

I have an issue with a C# PayTrace Gateway. The below code was working fine until yesterday when I believe they turned off SSL3 due to the Poodle Exploit. When running the code below we got the following message. The remote server has forcefully closed the connection. After doing some research on the problem we determined that because our IIS Server 7.5 was configured to still use SSL3, C# defaulted to SSL3, which PayTrace would forcibly close the connection. We then removed SSL3 from the server. Which then lead to the following error: 

**The client and server cannot communicate, because they do not possess a common algorithm.** 

My guess is that there are additional SSL algorithm we need to install on the server now that SSL 3 is removed. Our IT staff claims that TLS 1.1 and TLS 1.2 are working and that ASP.NET should be now defaulting to those. But I feel like there still must be something else we need to install on the server, I have no knowledge of SSL Algorithms so I have no idea where to begin.

    ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;
    String sRequest = &quot;PARMLIST=&quot; + Url.Encode(postUrl.ToString());
    wClient.Headers.Add(&quot;Content-Type&quot;, &quot;application/x-www-form-urlencoded&quot;);
    string sResponse = &quot;&quot;;
    sResponse = wClient.UploadString(PayTraceUrl, sRequest);

Also, just an FYI, this issue is also happening when we connect to First Data E4 gateway so it&#39;s not just a PayTrace thing. My guess is that as more gateways turn off access to SSL3 we&#39;ll continue to run into issues with other gateways until this can be resolved on the server. Also, I did find a few suggestions online, some suggested placing the following code right before making the outbound request: 

    ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;

Unfortunately that did not work either, same error. Which is why I&#39;m thinking something additional needs to be installed on the IIS7.5 server. I&#39;m just not sure what.

HTTP Error 404.3-Not Found in IIS 7.5

We have recently upgraded all of our WebForms projects to .NET 4.5, and encountered a parser issue when loading pages with an `iFrame` element. We have corrected this by converting of the `iFrame` from `HtmlGenericControl` to `HtmlIframe`. This has corrected all of the parser errors when we run our code locally.

When we deploy the app, we get the following error message:

&gt;Parser Error Message: The base class includes the field &#39;frame&#39;, but its type (System.Web.UI.HtmlControls.HtmlIframe) is not compatible with the type of control (System.Web.UI.HtmlControls.HtmlGenericControl).**

When I deploy the old code with the `HtmlGenericControl` the error goes away suggesting that even though we have installed .NET 4.5, the server is still using an older version? 

I&#39;ve tried removing and reinstalling .NET it making sure to register asp with IIS.

I have a new Win7 workstation and I am trying to get ScrewTurn Wiki to run on the machine.  My STW installation is using the file system option to store its data, and as such I need to give write permissions to the ASP.NET worker process in the folder the website is installed in.  

HOWEVER, I cannot seem to be able to come up with name of the worker process in Win7 in order to add it to the permissions for the folder.  In XP it was ASPNET_WP, if I remember correctly, but that is not its name in Win7.  

Can someone please tell me?

Edited to add:

In response to @Dragan_Radivojevic, here&#39;s what the application pool in question looks like (named ScrewTurnWiki):

How do I give ASP.NET permission to write to a folder in Windows 7?

I want to run my application from IIS on my local machine. I created the virtual directory and added the application to it and in the properties folder of the application I checked the radio button &#39;Use Local IIS Webserver&#39;. I then started running my application but I&#39;m getting the following error:

&gt;Unable to start debugging on the webserver.see help for common configuration errors.Running the webpage outside of the debugger may provide further information.
&gt;
&gt;Make sure the server in operating correctly.Verify there are no syntax errors in web.config by doing a debug.Start Without Debugging.You may also want to refer to the ASP.NET and ATL Server debugging topic in the online documentation.

How do I get rid of this error?

I&#39;m using Visual Studio 2010 on Windows 7 and IIS 7.5.

IIS error, Unable to start debugging on the webserver

I&#39;m trying to run an ASP.NET MVC 2 web application under IIS on Windows 7, but I get a 403.14 error. Here are the steps to reproduce:

 1. Open Visual Studio 2010
 2. Create a new ASP.NET MVC 2 project called MvcApplication1
 3. Shift+F5 to run the app. You should see `http://localhost:{random_port}/` and the page will render correctly.
 4. Click on MvcApplication1, and select &quot;Properties&quot;. Go to the &quot;Web&quot; section. 
 5. Select &quot;Use Local IIS Web server&quot; and create a virtual directory. 
 6. Save.
 7. Shift+F5 to run the app. You should see `http://localhost/MvcApplication1/` and an IIS error `HTTP Error 403.14 - Forbidden The Web server is configured to not list the contents of this directory.`.

It&#39;s clear that for whatever reason, ASP.NET routing is not working correctly. 

Things I&#39;ve already thought of and tried:

 - Verified that all IIS features are enabled in &quot;Turn Windows features on or off&quot;.
 - Verified that the default website is configured to use .NET 4.0
 - Reassigned ASP.NET v4 scripmaps via `aspnet_regiis -i` in the `v4.0.30319` directory.

Here&#39;s the most amazing part - this is on a *just-built* machine. New copy of Windows 7 x64 Ultimate, clean install of Visual Studio 2010 Premium, no other websites and no other work performed. 

Anything else I can try?

Are there any other steps I forgot to take to get this working?


Notes: I installed IIS 7.5 after installing VS 2010 RC. I used the built-in &quot;Create Virtual Directory&quot; button under the &quot;Web&quot; tab in the MVC project&#39;s &quot;Properties&quot; in Visual Studio 2010. I made sure that the application is using the ASP.NET 4 App Pool.

GZip Compression On IIS 7.5 is not working

My CPU usage is 100% most of the the time in Windows Server 2008-R2 with my own vps, vmware, quad core, and 4GB Ram. When I open windows Task Manager and go to the resource monitor I see that 100% usage is because of `workerprocess.exe`.  I have 3 websites in my IIS.  

* How can I figure out which web site causes that usage
* How can I limit it to 80% usage of CPU?  
* Could it be a DDOS attack?  
* Is there any way to prevent DDOS?  
 
I installed eset-nod32 on my vps, but it doesn&#39;t show any attack in the logs.  I&#39;ve tried searching about IIS and preventing DDOS, and just found an extension for banning IP addresses, but how can I find which IP address are generating traffic?  


The web site is written in `ASP.NET` and `C#`. How can I determine what is happening on that web site and which lines of codes are causing that cpu usage?

Also, one of my web sites should access administrator&#39;s desktop and read and write some files.  So because of that I changed its application pool -&gt; identity (Process Model) to local system, and I don&#39;t know if it is related with the CPU usage or not.


How prevent CPU usage 100% because of worker process in iis

I have classic ASP running on IIS 7. 

Even though I configured the ASP &quot;Debugging Properties&quot; to &quot;Send Errors to Browser = True&quot;, the web app REFUSES to send errors to the browser and continues to send a 500 internal server error.  

- My browser has &quot;Show Friendly HTTP Error Messages&quot; unchecked. 
- Failed Request Tracing is installed (not sure if that&#39;s related)
- Happens both on web pages loaded locally on the server and remotely
- The App Pool is integrated (not sure if that matters)

Any ideas? 


Classic ASP on IIS7: refusing to send errors to browser on 500 Internal Server Error

(This is a question about a vague problem.  I try to present all relevant data, in the hope that someone has helpful information; apologies for the long description.)

**Our web app**

We have a .NET 4 web application running in IIS 7.5 accessing Active Directory and a SQL Server database.

This web application is running under a virtual &#39;app pool identity&#39;, by setting the Identity of the application&#39;s application pool to [ApplicationPoolIdentity](http://msdn.microsoft.com/en-us/library/bb386459.aspx).  A concise description of virtual identities can be found in [a StackOverflow answer](https://stackoverflow.com/a/3680803), and the blog post to which it refers: an app pool identity is just an additional group which is added to the web application&#39;s worker processes which is running as &#39;network service&#39;.  However, [one source](http://forums.iis.net/p/1171701/1957045.aspx#1957045) vaguely suggests that &quot;Network Service and ApplicationPoolIdentity do have differences that IIS.net site documents do not publish.&quot;  So a virtual identity might be more than just an additional group.

We chose to use ApplicationPoolIdentity, as opposed to NetworkService, because it became the default in IIS 7.5 (see, e.g., [here](http://msdn.microsoft.com/en-us/library/bb386459.aspx#attributesAndElementsToggle)), and per Microsoft&#39;s recommendation: &quot;This identity allows administrators to specify permissions that pertain only to the identity under which the application pool is running, thereby increasing server security.&quot; (from [processModel Element for add for applicationPools [IIS 7 Settings Schema]](http://msdn.microsoft.com/en-us/library/bb386459.aspx#attributesAndElementsToggle)) &quot;Application Pool Identities are a powerful new isolation feature&quot; which &quot;make running IIS applications even more secure and reliable. &quot; (from [IIS.net article &quot;Application Pool Identities&quot;](http://learn.iis.net/page.aspx/624/application-pool-identities/))

The application uses Integrated Windows Authentication, but with [`&lt;identity impersonate=&quot;false&quot;/&gt;`](http://msdn.microsoft.com/en-us/library/72wdk8cc.aspx), so that not the end user&#39;s identity but the virtual app pool identity is used to run our code.

This application queries Active Directory using the [System.DirectoryServices](http://msdn.microsoft.com/en-us/library/system.directoryservices.aspx) classes, i.e., the ADSI API.  In most places this is done without specifying an additional username/password or other credentials.

This application also connects to a SQL Server database using `Integrated Security=true` in the connection string.  If the database is local, then we see that `IIS APPPOOL\OurAppPoolName` is used to connect to the database; if the database is remote, then the machine account `OURDOMAIN\ourwebserver$` is used.

**Our problems**

We regularly have issues where a working installation starts to fail in one of the following ways.

 * When the database is on a remote system, then the database connection starts to fail: &quot;Login failed for user &#39;NT AUTHORITY\ANONYMOUS LOGON&#39;. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors.&quot;  The previous error is &quot;Error: 18456, Severity: 14, State: 11.&quot;  So it seems that now `OURDOMAIN\ourwebserver$` is not used anymore, but instead anonymous access is attempted.  (We have anecdotal evidence that this problem occurred when UAC was switched off, and that it went away after switching on UAC.  But note that changing UAC requires a reboot...)  A similar problem is reported in [IIS.net thread &quot;use ApplicationPoolIdentity to connect to SQL&quot;](http://forums.iis.net/t/1181039.aspx), specifically in [one reply](http://forums.iis.net/p/1181039/2010748.aspx#2010748).

 * Active Directory operations through ADSI (System.DirectoryServices) start to fail with error 0x8000500C (&quot;Unknown Error&quot;), 0x80072020 (&quot;An operations error occurred.&quot;), or 0x200B (&quot;The specified directory service attribute or value does not exist&quot;).

 * Signing in to the application from Internet Explorer starts to fail, with HTTP 401 errors.  But if in IIS we then put NTLM before Negotiate then it works again.  (Note that access to AD is needed for Kerberos but not for NTLM.)  A similar problem is reported in [IIS.net thread &quot;Window Authentication Failing with AppPool Identity&quot;](http://forums.iis.net/t/1171701.aspx).

**Our hypothesis and workaround**

At least the AD and sign-in problems always seem to go away when switching the application pool from ApplicationPoolIdentity to NetworkService.  (We found [one report](http://forums.iis.net/p/1181039/2010748.aspx#2010748) confirming this.)

Page [&quot;Troubleshooting Authentication Problems on ASP Pages&quot;](http://msdn.microsoft.com/en-us/library/ms180891.aspx) has some suggestions related to primary vs. secondary tokens, and what I find encouraging is that it links the first two of our errors: it mentions `NT AUTHORITY\ANONYMOUS LOGON` access, and AD errors 0x8000500C and &quot;The specified directory service attribute or value does not exist&quot;.

(The same page also mentions ADSI schema cache problems, but everything we can find on that topic is old.  For now we consider this to be unrelated.)

Based on the above, our current working *hypothesis* is that, only when running under a virtual app pool identity, *our web application (IIS? worker process?) suddenly loses its primary token*, so that IIS only has a secondary token, so that all access to Active Directory and SQL Server is done anonymously, leading to all of the above errors.

For now we intend to switch from ApplicationPoolIdentity to NetworkService.  Hopefully this makes all of the above problems go away.  But we are not sure; and we would like to switch back if possible.

**Our question**

Is the above hypothesis correct, and if so, is this a bug in IIS/Windows/.NET?  Under which circumstances does this primary token loss occur?

HTTP Error 500.19 - IIS 7.5 Error 0x8007000d

I am getting the following error when I try to launch my ASP.Net Core App using IIS Server v7.5 ... I published the website (File System option in Visual Studio) to a specific directory successfully. It launches fine from approot/web.cmd file. But when I try to hook it up to IIS Server and point it to the wwwroot folder, I get the following error:

&gt; HTTP Error 500.19 - Internal Server Error

&gt; The requested page cannot be accessed because the related configuration data for the page is invalid.

&gt; - Detailed Error Information
&gt; - Module	IIS Web Core
&gt; - Notification	Unknown
&gt; - Handler	Not yet determined
&gt; - Error Code	0x8007000d
&gt; - Config Error	
&gt; - Config File	\\?\D:\WebDevelopment\UAT\creativeNamePROD\wwwroot\web.config
&gt; - Requested URL	http://10.2.177.226:59/
&gt; - Physical Path	
&gt; - Logon Method	Not yet determined
&gt; - Logon User	Not yet determined
&gt; - Failed Request Tracing Log Directory

Below are two different web.config files I tried any neither one worked. When I try to get into Configuration Editor within IIS, I get an unclear error as well. Any help would be greatly appreciated!!!

    &lt;configuration&gt;
    &lt;system.web&gt;
      &lt;httpRuntime maxQueryStringLength=&quot;64768&quot; maxUrlLength=&quot;65536&quot; /&gt;
    &lt;/system.web&gt;
    &lt;system.webServer&gt;
    &lt;security&gt;
      &lt;requestFiltering&gt;
        &lt;requestLimits maxQueryString=&quot;64768&quot; /&gt;
      &lt;/requestFiltering&gt;
    &lt;/security&gt;
    &lt;handlers&gt;
      &lt;add name=&quot;httpplatformhandler&quot; path=&quot;*&quot; verb=&quot;*&quot; modules=&quot;httpPlatformHandler&quot; resourceType=&quot;Unspecified&quot; /&gt;
    &lt;/handlers&gt;
    &lt;httpPlatform processPath=&quot;..\approot\web.cmd&quot; arguments=&quot;&quot; stdoutLogEnabled=&quot;false&quot; stdoutLogFile=&quot;..\logs\stdout.log&quot; startupTimeLimit=&quot;3600&quot;&gt;&lt;/httpPlatform&gt;
    &lt;/system.webServer&gt;
    &lt;/configuration&gt;

Web.config #2 -gets the same error

    &lt;configuration&gt;
      &lt;system.webServer&gt;
        &lt;handlers&gt;
          &lt;add name=&quot;httpplatformhandler&quot; path=&quot;*&quot; verb=&quot;*&quot; modules=&quot;httpPlatformHandler&quot; resourceType=&quot;Unspecified&quot; /&gt;
        &lt;/handlers&gt;
        &lt;httpPlatform processPath=&quot;..\approot\web.cmd&quot; arguments=&quot;&quot; stdoutLogEnabled=&quot;false&quot; stdoutLogFile=&quot;..\logs\stdout.log&quot; startupTimeLimit=&quot;3600&quot;&gt;&lt;/httpPlatform&gt;
      &lt;/system.webServer&gt;
    &lt;/configuration&gt;
