Version Information: Microsoft .NET Framework Version:1.1.4322.2032; ASP.NET Version:1.1.4322.2032
I TRIED EVERYTHING, CHANGED THE PERMISSIONS ON REGISTRY SETTINGS, UNINSTALLED DOTNET FRAMEWORK, REINSTALLED DOTNET FRAMEWORK, TRIED MS KB ARTICLE 329291, RESEARCHED ON THE TECHNET, MSDN, GOOGLE, GAVE ADMINISTRATOR PERMISSIONS TO ASPNET ACCOUNT ETC ETC -- NO LUCK!!!
WELL FINALLY BEFORE TURNING THE COMPUTER OFF, I GAVE A LAST TRY AND BINGO!!! IT WORKED!!!
SOLUTION IS AS FOLLOW (THIS SOLUTION IS FOR DEVELOPMENT ENVIRONMENT ONLY):
1. Give the ASPNET user permission to read the Security eventlog registry entry.
Run regedt32
Navigate to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Security
Right click on this entry and select Permissions
Add the ASPNET user
Give it Read permission
2. Change settings in machine.config file
Run Explorer
Navigate to WINDOWS or WINNT folder
Open Microsoft.NET folder
Open Framework folder
Open v1.1.4322 folder (folder name may be different, depending on what dotnet version is installed)
Open CONFIG folder
Open machine.config file using notepad (make a backup of this file first)
Locate processmodel tag (approx. at line 441)
Locate userName="machine" (approx. at line 452)
Change it to userName="SYSTEM"
Save and close the file
Close Explorer
3. Restart IIS
Run IISReset
THAT'S IT. HAPPY PROGRAMMING...
