SYMPTOMS

Consider the following scenario:
  • An application is built by using the Microsoft .NET Framework 2.0.
  • The application runs in the Microsoft .NET Framework 2.0.
  • The application runs under a user account context.
  • No user profile is associated with the user account context.
In this scenario, the application may crash, or you may receive an access violation error message. If you debug the crash, you find an access violation in the mscorwks!SecurityConfig::GetCacheEntry function.

If you experience this problem in a Microsoft ASP.NET application, you receive error messages in the event log that are similar to the following:

Error message 1
Event ID : 1023
Raw Event ID : 1023
Record Nr. : 14
Category : None
Source : .NET Runtime
Message : NET Runtime version 2.0.50727.42 - Fatal Execution Engine Error (7A05E2B3) (80131506)
Error message 2
Event ID : 1000
Raw Event ID : 1000
Record Nr. : 15
Category : None
Source : .NET Runtime 2.0
Error Reporting Type : Error
Message : Faulting application w3wp.exe, version 6.0.3790.1830, stamp 42435be1, faulting module mscorwks.dll, version 2.0.50727.42, stamp 4333e7ec, debug? 0, fault address 0x000e9f96.
Notes
  • Error message 2 immediately follows error message 1.
  • This problem occurs with ASP.NET 2.0 applications. This problem may occur with other types of applications that run under non-interactive accounts, such as Windows services.
Additionally, in Microsoft Windows SharePoint Services 3.0 or in Microsoft Office SharePoint Server 2007, you may be prompted for authentication when you connect to the Site Usage Report page of a Web site to view the usage data for that Web site. Then, you may recieve the following error message:
The request failed with HTTP status 401: Access Denied
The following event is logged in the event log:

Event ID : 1023
Raw Event ID : 1023
Record Nr. : 14
Category : None
Source : .NET Runtime
Message : NET Runtime version 2.0.50727.42 - Fatal Execution Engine Error (7A05E2B3) (80131506)

MORE INFORMATION

For more information, click the following article number to view the article in the Microsoft Knowledge Base:
824684  (http://support.microsoft.com/kb/824684/ ) Description of the standard terminology that is used to describe Microsoft software updates
When the common language runtime (CLR) starts, the CLR verifies that the user profile exists. If the user profile does not exist, a null reference is put in the user policy cache. If the user profile is created during policy resolution, the CLR tries to remove the reference to the null reference in the user policy cache. When the CLR cannot remove the reference to the null reference in the user policy cache, the .NET Framework 2.0 crashes.
