I have a file on the win2k file server around 100 mb, I
need to copy this file to my local machine, but it took 50
minutes to finish it, which I don't think it's normal.
since I can copy 300 mb files in 10 mintues from another
server to my same local pc.
Is there anything wrong, or anything related to the
settings in the file server?
is there anything related to the caching, network?
the network is working fine, we can get connected to the
internet without any problems.

I am using 2 protocol, NETBEUI and TCPIP, but I am not
sure which one is running as default.

thanks & regards

Is the server's nic perhaps set at 10Mbps instead of 100Mbps?  Could it be half duplex instead of duplex?

Just some thoughts.

David - just guesses, but:
- one server is highly fragmented, the other isn't.
- one server is extremely busy, or has an algorithm that
honors small file requests before yours, and the other
isn't/doesn't.
- there are more machines between you and the slow server,
and one or more is waiting for the entire 100MB to
arrive/reassemble before forwarding, or one link along
the path is extremely slow for some reason.
- there is some persistent surface or file corruption
requiring loops of error correction or access retries
before the 100MB file is available.

Quick test: if you can move that file to the faster server,
see what happens when you copy it.

Are both servers W2k? Have you notified the sys/netadmin of
this oddity? The cause and cure may be trivial.
