Performance plummets when server in 2-PC network is swapped

Posted on 2005-05-03

I had a 2-PC network.  Call the 2 machines "server" and client.  (Neither server NOT client accesses the Internet - it is a 'closed' network).

What we did:  We replaced the server with a much faster model.  EVERYTHING works!  server can see client, client can see server, the PCs can exchange files.  Applications with data on server work.  The only problem???   S  L  O  W  !   (especially when copying files).

What did I do?  
    1.  I set up the new server (made it part of the workgroup)
    2.  I pulled the CAT-5 cable out of the back of the old server and plugged it into the back of the new server.

And, as I said, everything works but   S  L  O  W.
The server itself is lightening fast but it took me like 60 minutes to copy a file (from the server to the client) that normally takes about 4 minutes.

One person suggested that the problem may be the "duplex settings" of the network cards involved OR the cabling.  If the cabling were "bad", then it is bad in a way that did not "offend" the old server but DOES "offend" the new server.  I suppose that is possible.

Thank you.

    First line should read "Neither server NOR client".  
    I errorneously wrote "Neither server NOT client"

    I agree it might be the settings on your new server's network card.  The following assumes you're using Windows.

    On your server, go to the Properties of your Local Area Connection.  Click on the Configure button, then click on the Advanced tab.  Select Link Speed & Duplex.  Make a note of what the setting is (probably Autodetect).  Change the setting to 10Mb/Full duplex, click OK.  See if that improves things.  If so, repeat the steps, but this time try 100Mb/Full duplex.

    If the above doesn't work, provide more details of each machine's operating system and how they're connected, whether by switch, hub or crossover cable.

    Good luck.
