Are you sure in the registry the RDP port is set 3389?
Guys this was it. I had to go into the registry and change it from another port; The person who set this up probably changed this as a way to prevent any tampering. Well played other guy... well played.
What threw me off is that all the inbound rules for the firewall were set to 3389. Everything was default except for this one thing. Thanks everyone!
(The registry edit was HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\ and then PortNumber subkey. Double click that and chang HEX to Decimal and there's your port. Mine was set to some random number that had no inbound rules for it anyway)
