PC Locks Up Everyday around 5pm
Posted on 2009-02-21
I have a small office running SBS 2003. Their server is a relatively new Dell PowerEdge and there are 7 PC's all running XP Pro SP3. There had been no software updates applied to the server in 18 months. They rely heavily on a SQL based software program named Practice CS from Thomson Reuters. A week ago, I applied roughly 37 SBS updates updates to bring the server current. Since applying the updates 1 PC locks up everyday around 5pm. When I say locks up, I mean all applications running at the time lock up ~ with the exception of Internet Explorer, chich continues with excellent response rates. Task Managers shows little CPU utilization 0-7%. No corresponding errors in the event logs for either the PC or the server and other PC's continue to work fine. There are no scheduled tasks that occur around 5pm. I am not willing to roll back all of the updates to resolve this problem. Anybody have any ideas?
