server 2003 SBS XP client connnections very slow!!

Hi, have a really urgent issue!
I have a 2003 sbs server running fine, DNS, DHCP etc.... wise but the three XP client PC's that connect to the network have very slow connections from the server when trying to run a program via a shortcut which looks at a map drive location.

This server has been running fine for two years, but I went to restart the server last Sunday and it didn't reboot.  After a while I got the server back up but since then all connections to XP client PC's are running very slowly.  One thing I did try on Sunday was removing the network card and reinstalling it which allowed the server to come back up.  Then configured the network card with the server IP address etc...  Since then very slow connections.

I have just run MBA and it told me to disable "DisableTaskOffload" within the registry which I've done but no difference...

I would be very grateful for a speed reply as sitting at clients site pulling my hair out!

Verify in the properties of the storage controller that all physical disks are working and that all mirroring or rebuilding is finished.

Download and install the SBS BPA in additon to the MBA, then fix everything it finds.  

Open Device Manager - view hidden devices and verify that there are no hidden nics or other devices.  If so, clean that up.

Then run the CEICW just to flush out the rubbish left over from reinstalling the NIC.

When viewing all hidden devices within Device Manager I see the attached.  Normally I only see the Inter Pro network card.

That looks ok.  When you say "normally", you mean if hidden devices are not shown?

Have you looked at the rest of the suggestions?

I found the issue myself, it was the network card not linking to the switch at 1GB, but the server connection wrongly said it was connected at 1GB.
