I have a windows server 2003 network running a domain controller. All computers in the LAN are xp. I have a few outside employees that have macs that need to access their desktop pc's. On an outside xp computer, I can connect to our VPN and then remote desktop to whatever computer I want within the lan. On the mac, I created a VPN and connect but it won't connect to any windows computers from the mac RDC. I have even tried to connect to one of our servers but with the same results. I can ping the IP's and get a reply back. If I disconnect the VPN and try the RDC to the IP that has been set up to accept outside connections and route them to our terminal server, it works fine.
Seems like it must be something simple I'm missing.
