i would like to transfer data between 2 LANs. The first LAN (LAN 1) has a client/server configuration that is active directory integrated. The second LAN (LAN 2) is basically a peer-to-peer network, although one computer that contains a 4D database  runs windows 2000 server operating system and acts as a server for the other 2 workstations in the workgroup. What I would like to do is have a workstation in LAN 1  be able to communicate to the server in LAN 2, while logged in LAN 1. Is that possible?  If yes, how do i do it?

I assume these lans are on different Subnets. If this is the case, you'll  need a router of some sort to route traffice b/w the lans. Are they in different buildings? If so, you'll need a VPN or RAS setup. Another option, if you just need to transfer data, would be to set up an FTP server accessable to the Internet and use that as your intermediary to transfer files..

If your first Lan is AD and your second isn't, a workstation from Lan 2 would need AD credentials (user name and password) to access resources once the Lans are routed together. A workstation from LAN 1 accessing LAN 2 would need local credentials to access LAN 2's resources (just like a workstation on LAN2).

from what i understand is that the networks are connected via a win2000 server, if so you'll have to enable RRAS routing and remote access, in the routing area you'll have to make sure the server will be able to forward information from and to the lans.

more info on the network setup would be helpfull

If both LANS are physically located near eachother... install a second NIC into the Win2000 (LAN2) server with 4D database.  Assign that nic an IP address from LAN1.  This second NIC will act as a Bridge between the LANs.

Install second NIC in the server from LAN 2 and connect it to LAN 1.  Make static IP's. Make sure crossover cable is there.
