NT4 RAS with Exchange –

I have a RAS server running on an older NT box with 2 modems, which, when dialed up on, connect users without a hitch. The problem for me, is that the Exchange server (running on a newer Dell PowerEdge) is inaccessible.

I can ping Exchange on the LAN. Using the modem/PPP client on the RAS, after connected, I cannot ping the Exchange server. Any suggestions – little help here!

Thanks,
Casey
