Trouble Installing ArcGIS Server 9.3.1

Quick note for others that may run into this. Last week, we got the ArcGIS Server 9.3.1 update. I was excited to get this installed and tested after hearing about all of the speed improvements that have been promised. Anyway, long story short, got an error when trying to install.

"due to an error in software restriction policy processing..."

That was the gist of the error. Anyway, looking in event logs, this error appeared:

"The installation of F:\ArcGIS-Windows\ArcGISServerDotNet931.msp is not permitted due to an error in software restriction policy processing. The object cannot be trusted."

Looking that up, I was able to track down this patch from microsoft: http://www.microsoft.com/downloads/details.aspx?FamilyId=8EFFE1D9-7224-4586-BE2B-42C9AE5B9071&displaylang=en

That fixed the problem.
