My SBS 2008 installation is pretty good, but one area I’ve noticed some problems was with ForeFront. I either had errors or at best warnings all the time about the scan engines. I would go and hit a manual update, but the bar would be 30-90% across and suddenly stop. When I looked in the event log I could see errors like these below. Searching the internet delivered me the KB article http://support.microsoft.com/kb/939411/en-us which talks about timeout issues, however even with the recommended change things did not resolve themselves.
