Intermittently, my workstations lose their connection to the SBS server. This happens about once a week. When it does happen I reboot the server, and everything starts working again. Then a week later it does it again.
There are about 30 workstations. The server is a dual xeon 2.8 with 4gb ram. The server has been running for about 1 year and 4 months, without this issue, which started about 1 month ago. SBS SP1 and exchange sp2 have been installed. I have norton Corp 7.6 which reports no viruses, but I dont have mail protection installed. Sometimes the server runs low on memory; there is only about 200mb of free memory no matter what I do. If you need any other info just ask me.
