Question : .NET Run Time Error in App Event Log

I have a Server 2003 SP2 that is presenting the following error in the Application Event Log, there seems to be about 50 of them per day, what is the cause. ?

The description for Event ID ( 0 ) in Source ( .NET Runtime ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: .NET Runtime version 1.1.4322.2379- w3wp.exe - Common Language Runtime Debugging Services: Application has generated an exception that could not be handled.

Process id=0xa58 (2648), Thread id=0x9b8 (2488).

Click OK to terminate the application.
Click CANCEL to debug the application..

Try this dont forget to backup first:

1)
Start >> Run >> regedit {OK}
HKLM\SYSTEM\CurrentControlSet\Services\EventLog\Application\ Source>
Under that key you should fina a parameter "EventMessageFile". Ensure that the path is correct there.

2) You can try Full Control permissions on:
HKLM\Software\Microsoft\.NETFramework\policy\AppPatch\

3) Try installing .NET Framework Service Pack 2 from Windows Update
