DUEL NETWORKS

I have a workgroup with several windows NT workstations running the FDDI protocol. I also have a LAN/WAN running Win2000/WinNT servers and clients (TCP/IP). I would like to be able to join both networks to allow remote access to the workgroup machines from my LAN/WAN client machines. I (as do we all) have a limited budget to accomplish this. Please provide as much detail as possible on how this can be best accomplished.

Thanks in advance.
