Webservice: "The ASP.NET process identity does not have read permissions to the global assembly cache."

  Try reinstalling ASP.NET on your box using the Administration utility (2.0.50727) to install and uninstall ASP.NET on the local machine.:

  1. Open a command prompt
  2. Stop IIS: iisreset /stop
  3. Change to the .NET Framework 2.0 root directory: C:\winnt\Microsoft.Net\Framework\v2.0.50727\
  4. Reinstall ASP.NET 2.0 by using the following command: aspnet_regiis -i command.
  5. Start IIS again after it has been run: iisreset /start

  Try to access your web page again.

  Hi, I have the same problem. But I have user /ASPNET correctly created and it has modify access over all inetpub/wwwroot directory (folder). I cannot reinstall, because there is over hundred another webs on the server and server has contracted high reliability :(

  I'll second that. It's a nice concise guide to troubleshooting ASP.NET 2.0 & IIS installation issues.

  This has been resolved!!!!
  
  The problem is quasi-environmental. During the development of this project there were several power failures and when the power returned there was no communication with the web....
  
  Because of the error messages it appeared perhaps that IIS itself was corrupted in the XP Pro SP2 system. IIS was uninstalled and reinstalled. But IIS was not the problem. Actually a router had died.
  
  What I did find out were several things. If IIS is ever uninstalled, in relation to ASP at a minimimum a full de-installtion of VS2005 and IIS is required.
  
  Then a resinstallation FIRST of IIS followed by VS2005.
  
  I didn't have any luck with this. Actually I had to reinstall my entire XP system and reinstall everything and now the original code is working.

  I was also getting this message. Chronologically, in the Event log, there are always two messages, first:

  Event Type: Error

  followed by a:

  Description:
  Failed to execute the request because the ASP.NET process identity does not have read permissions to the global assembly cache. Error: 0x80070005 Access is denied.

  This happened even when I create a web site from scratch on my development machine, with just the basic site template, and add the following code in the Page_Load method, put a breakpoint on it, and execute:

  Debug.Write("test");

  I get a dialog with HTML on it in .NET 2005 stating "Unable to start debugging on the development server". The same message is displayed when I use the IIS MMC snap-in to right-click the website's Default.aspx page, and choose browse:

  Server Application Unavailable

  I am using Windows XP (which has IIS 5.5). Firstly, note that computers running IIS 5.5, if running ASP.NET 2.0 along with a previous version of the framework (1.0 or 1.1), cannot share the same ASP.NET worker process. To fix this problem, ensure that all ASP.NET Web Sites are configured to run in their own separate process. For more information, see the following link: http://support.microsoft.com/default.aspx kbid=811320

  Next, as the problem indicates, there is a permissions issue with the ASP.NET account accessing the GAC (files stored in %windir%\assembly (eg. C:\WINNT\assembly). Have a look at http://support.microsoft.com/default.aspx kbid=811320 for details. Specifically, one thing that I noted was that the following command didn't always work as expected:

  C:\>cacls %windir%\assembly /e /t /p domain\useraccount:R

  A tip -- BEFORE trying out the above command, I would suggest downloading the excellent AccessEnum utility from http://www.sysinternals.com/Utilities/AccessEnum.html, running it, and typing C:\WINNT\assemby in the top textbox, then click the "Scan" button at the bottom. I ensured that the ASP.NET account specifically didn't have DENY permissions for ANY directory. Actually, the ASP.NET account shouldn't even be in the ACL (Access Control List), because by default, the ASP.NET account belongs to the Users group, which already has READ, EXECUTE, and LIST permissions. Note that by right-clicking on a file here, and choosing properties, it is possible to get the Windows File properties for the file, which includes the "Security" tab, for adjusting the ACL properties.

  One further thing :- by default, the %WINDIR%\Assembly folder has a modified view when viewed in Windows Explore, and the Security tab of the File properties for this folder is not available. It is the C:\WINNT\Microsoft.NET\Framework\v2.0.50727\shfusion.dll file that controls this. To access file properties, and allow viewing of this folder, unregister the file:

  C:\>regsvr32 -u C:\WINNT\Microsoft.NET\Framework\v2.0.50727\shfusion.dll

  and to re-register the file

  C:\>regsvr32 C:\WINNT\Microsoft.NET\Framework\v2.0.50727\shfusion.dll

  Anyway, once I had ensured that the ASP.NET account wasn't explicitly denied permissions from using files in the GAC, and ensured that I wasn't starting an ASP.NET 1.1/1.0 application first in a shared pool, and then trying to start an ASP.NET 2.0 application (on my IIS5.5 Windows XP machine), the error went away!

  Happy configuring.

  You need to give the account ASPNET read access to the web site's application directory.

  You're welcome.

  Please explain what you mean in the above post.  I have run into the same error message, but I got there a much different way.  I am running my app an a domain controller, so I had to change the machine.config to use DOMAIN\ASPNet userid.  Once I did that the error started appearing.  My \WINNT directory has "Authenticate Users" with read, list and execute permissions and I can not set permission on \WINNT\assembly directly so, I don't know which way to proceed.

   

  Thanks

  Actually, most of the time this should go away just adding .\ASPNET user to the directory users.
  
  

• Eric Feunteun

  I used aspnet_regiis -ga domain\processusername

  This resolved the issue listed above by authorising the ASP.NET process defined in the Machine.config to the IIS Metadata.
