Remote Access problem

[Hanson]

We have three branches in the company connected by T1 routers.

For some reason, when you use dial up networking, you can hit all of the servers and workstations in the branch that contains the RAS server. But it will not see any of the systems on the other side of the T1 lines. Can't browse, can't use UNC name. The login script displays this error when mapping a server on the other side of the T1:

Error 53: computer name not specified

Is there a setting I'm missing somewhere? All branches use the same subnet.

Do the routers access list have any IP specified security e.g if you don’t have a 234.45.0.0 address you can access anything on the other side of this router.
