aspnet_wp.exe (PID: xxxx) stopped unexpectedly

Are you having an error aspnet_wp.exe (PID: xxxx) stopped unexpectedly. I have recently installed Visual Studio 2008 on my computer and then I try to compile one of the web applications which I have just downloaded from Team Foundation Server (TFS) and it compiles fine. However when I try to debug the application, I get an error “Server Application Unavailable”. After several attempts I then check the event logs to look for any hints of solving this error. As I went through the log I saw a log entry with an error aspnet_wp.exe (PID: xxxx) stopped unexpectedly.

After looking up on Google I could not find an answer to the solution so I continued to look through the event log and then I saw another entry log with this error message "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." I then quickly realize that ASPNET account need to have access to the web application folder. The application run successfully in debug mode after the ASPNET account has permission to access the web folder.

To provide the ASPNET account permission to access the folder:

Right click on the folder and click on property
Then select the Security tab
Click on Add and in the Enter the object names to select type in ASPNET and click on the Check Names button, and then click on OK to close the dialog. Ensure the ASP.NET Machine Account has modified access and click OK to exit the Properties dialog.
Recompile your web application and try to debug it again.

Thank you for idea.

The error message mention "not have read permissions to the global assembly cache" .

But in my case it was problem with permission to actual folder where web application stored.

Thanks again,
Daniel
