logging off the server

[WorkingHard]

Hi all
I have a SBS2003 server and one of our XPPRO machines keeps logging off for a reason we cannot find. Explorer on this pc also hangs from time to time. It is a very well used PC (mine) and i really do not want to start again with a new installed OS if it can be avoided. So, where do I start looking for the causes and how to fix?

many thanks

The Event Log would be a good place to start.

Then ensure that your AV and anti-malware software are up to date and run a full scan.

Check all the processes that are running on the system, check all the items that auto start.

Any more details on the network connection / type / card?

Check for updated drivers.
