We are running SBS 2003 R2 with Exchange 2003, MS SQL 2005 Standard Edition and Symantec Antivirus Corporate Edition. Note that the MS SQL 2005 is not the one with workgroup which comes with SBS. This box works fine until people use it but surprisingly it gets freezed when left idle. I mean, when all clients log off of the server, after an hour if someone tries to connect the server, it says server is not responding.
We need to manually reset the server to make it fine again. I tried to find out the cause of the problem but dint got anything. We have sufficient HDD space left, also temporary folders seems ok, neither there is any service scheduled that runs when the server is idle. Then what is making server unresponsive in idle mode?
