I've forwarded port 3389 to the IP. I can RDP into the IP internally, but not externally using the external IP address. Comes up with an error: Remote desktop can't connect to the computer. Remote desktop may be disabled or the computer may be off.
As I said I can RDP into it from within the network no problem. There is an SBS 2003 server that is doing DHCP. The router / firewall is a CISCO RVS2000.
