SCOM 2007 - Server Error in '/' Application. Access to the registry key 'Global' is denied

You see the following error "Server Error in '/' Application. Access to the registry key 'Global' is denied" when opening the Web Console in SCOM 2007.   This can also sometimes be seen with the word "Error" only.

 

Symptoms:

The console works initially, but after a few hours, days or weeks, the console returns the error.

Running IISRESET will also bring the Console back into a working condition.

 

FIX:

Performance monitoring group was missing the Aspnet and the SCOM Action Account  - Add these groups/accounts - full control.

Gave Network Service account full permissions on the following two folders: c:\windows\system32\inetsvr and c:\windows\debug\usermode.

Modify the permissions for the following:
C:\Windows\Debug\UserMode - Full Perm - Network Service
C:\Windows\System32\InetSrv - Full Perm - Network Service

HKCR\Installer\Assemblies\Global - Full Perm - Network Service and aspnet - Full Perm
