I have a Server 2003 Standard Edition SP2 that act's a a file sharing server as well as runs SQL 2005 and Backup Exec 12d. For some reason it freezes daily. Used to be every couple of Months. Nothing in the event logs points to anything. I have tried uninstalling Symantec Antivirus Corp. and have updated all firmware, drivers etc... I have installed all Microsoft updates. I have no idea what is causing it. The motherboard is an Intel SE7500CW2 with 4GB of RAM. I want to test the memory so can someone reccomend a good program? Is microsofts memory tester suitable for a server? Any help is appreciated.
