I have two servers that are just used as file servers though one is also running iPrint. The two servers hang completely at different times of the day, you cannot even use the keyboard, I need to reboot the server. It happens everyday. This two servers are totaly different, one is Nw6.5sp6 and the other is Nw6.5sp7, one has 2GB memory, the other has 4 GB, one is dell and the other is Hp, they are in different cabins. All the rest of my 25 servers have not problems though they are running different applications like Groupwise, zenworks...but this two servers are hanging everyday. Could it be something coming ftom the clients ? Is there anywhere I can look at the logs, or what was taking place when they hang.
