To change RDP port number (Windows server)
Run -> Regedit -> Hkey_Local_machine -> system -> currentcontrolset -> control -> Terminal server -> Winstations -> RDP-TCP -> portnumber (right side)
Also add an port exception in the Firewall.
example port numbers: 3315, 3325, 4124 etc. Note upto port 1024 are reserved ports. Hence do not use these ports.
