We have a Windows 2003 server acting as a domain controller, file server and DNS server.
Occasionally when opening a network drive in Windows Explorer or opening an application on the network it takes about 20 seconds for anything to appear. At other times the response is as quick as you would expect. I cannot find any reason why performance should vary when opening a server connection. It does not seem to relate to the amount of network traffic because it is a small network and the server and PCs are all connected to the same switch. The server is on a Gigabit port and the PCs on 10/100 speed ports.
It doesn't seem to be caused by any power save settings on client PCs that might cause network drives to go idle, or by antivirus software. I have tried changing these and the results are the same.
What might cause this sort of intermittent problem?
