I just installed SBS 2003 with SP1 and I'm trying to go through the event logs to do some cleanup. I installed WSUS on this machine as well, but when I restart, I get the following entry in my Application log. I tried giving Everyone and my IUSR account read access to C:\Program Files\Update Services\Selfupdate, but I'm still getting this error.
Event Type: Error
Event Source: Windows Server Update Services
Event Category: Update Services Service
Event ID: 506
Time: 3:39:47 PM
The SelfUpdate Tree is not working. Clients may not be able to update to the latest WUA client software and communicate with the WSUS Server.
