They currently have a 16-port hub with 10 or so clients, 3 ISDN routers, and a DSL router connected to it. The network, and the three networks connected through the ISDN share IPs in the public (but not registered) 1.32.44.x/8 range. Since the remote sites share the same IP range as the headquarters site, the ISDN routers are actually configured to bridge the networks. They currently run IPX/SPX, NetBEUI and TCP/IP as the protocol and NFS Maestro and the Microsoft Networking as the clients on all the PC nodes. They are currently running a system called XP on a Unix box (I assume it’s some type of loan software) that is using Samba to communicate with the PCs. All PCs are Win9x with a variety of NIC brands. The computers’ IPs are determined by a program in XP that tells what IP address to use next during it’s client setup proces ( which I have no firsthand knowledge of), they are statically assigned based on the “advice” of the XP system (I suspect it suggests the next highest IPaddress that isn’t c
