Win 95 slow since Win2K Server upgrade

Network was originally a peer-to-peer (with a “server” running Win98). Clients use Sage Line 50 and SuperOffice. All was working fine.

Network now has a dedicated Windows 2000 server. All clients can login fine, all the PC names and user names have been created on the server.

I have just ONE pc (running Win95) that runs VERY VERY slowly when accessing network resources.

The cabling and network points have been checked and are OK. The PC is not the fastest in the world (Pentium 1, 100MHz) but WAS working fine when it was accessing resources on the Win 98 “server”

Any suggestions on what could be causing the problem?
