Immediate things...

Are these slow machines trying to connect via NetBeui instead of TCP/IP.

Alternatively, are they engaged in some form of networking operation involving NetBeui? or IPX/SX?

Another thing to look at is their network protocol stacks: remove IPX/SX altogether and tell them to play Quake on another network. :) No kidding, if IPX/SX is being used on that network, it will stupefy TCP/IP. Try to push TCP/IP up to the top of their stacks if you can.

If it is the Win95 workstations in particular, check whether they have the latest Plus! upgrade - slow connection often indicates that they are using the old Winsock 1.

Make sure that they are all connecting to OURSERVER:D:\ourpath\ourdatabase.gdb with *no* variation on this connection string format; no mapped drives, no drive designators that are missing the backslash after, no IP addresses.
