Set up Lan-to-Lan connection

I have a 3Com remote access server 1500. I am trying to use it to connect Lan-to-Lan over regular phone lines (I know it is very slow, but our users just need to copy file once and a while). I have a domain at the satilite office on NT 4.0. The home office is Win 2000 server. The RAS 1500 is at the home office. I have configured the RAS for a lan-to-lan conncetion (it does have that capability), but I am not sure it is right. I have set up an NT 4.0 server at the satilite office end with a 56K modem. (I am not sure if I have the NT 4.0 Server set up correctly to recieve and route the calls.

Basically I need to know how to make this work.

Can anyone help?

Thanks
