Another Slow Network

Hi Everyon

I have been reading lots of posts here about very slow networking between Windows 2003 server and XP clients

I recently installed my Windows 2003 network using a Dell Poweredge 2600 server containing an Intel Gigabit network adapter. I am using Cisco 2950 switches which are forced at 100Mb Full Duplex, and have also set the card on the server to run at 100Mb Full Duplex too

I map drives on my clients, Windows XP and Windows 2000, via my login script to the server. When I try to copy data over it runs like a complete snail

For example I copied 400MB of files across and it took 4 minutes

To shed a little bit of light on this for other users of this board I tried the following as a test

I removed the server and a workstation from the Cisco Switch and plugged them into a plain ordinary dumb 3Com 100Mb hub. Both the cards on the server and workstation were then forced to run at 100Mb Half Duplex

I tried copying the exact same data, 400MB in size, and this time it took 45seconds!!

This make absolutely no sense to me whatsoever

Any help anyone can give would be greatly appreciated

My next step is going to be to try and copy files from a Windows 2000 PC to another Windows 2000 PC on the Cisco Switch. This should then rule out the switch at least, but judging by the mass of entries here I think it is more than likely a Windows fault

I will post more info when I have it

Many Thank

Graha
