We are a School with a Dell PowerEdge 2500 (Win2K) and a Dell PowerEdge 2600 server (Win2003) both authenticating users on our network. DHCP is running on the Win2K server and the Win2003 server is a file server. Both servers are plugged into the same Dell Powerconnect 2224 switch. Transferring a 36MB file from the 2600 to the 2500 takes 4 minutes 30 seconds. Transferring the same file back from the 2500 to the 2600 takes half that time. Both times seem excessive, but what is happening with the 2600 server to make it so slow? The 2600 is also very slow to browse the network (30-45 secs), whilst the 2500 is almost instantaneous. Help!
