Hey, I have tried to upgrade our server from WSUS 3.0 to WSUS 3.0 SP1 only to find out the install fails completly. Would some be able to have a look at the log and tell me if they have had the same problems. I have checked IIS to see if the "ASP .NET 2.0.50727" in the Web Serice Extensions page and it is Allowed. I have also tried installing to the dafault site or another website with still no success. If anyone has any ideas it would be greatly appreciated. Code SnippetWindows Server Update Services 3.0 SP1 could not configure the administration site or some of the virtual directories.
