Hit the Windows Key and type “regedit” and press Enter
This brings up the Registry Editor
Navigate to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp
Double Click the entry and select Decimal (unless you REALLY like Hex for some reason) and pick a port number. There’s rules for what port you’re going to want to use, but that’s a whole lesson in itself. Click HERE for a little bit more info on finding ports in use, etc.
Write down the port you picked. I recommend using a different port for each server for security, also if you have multiple computers attached to a router on the same public facing IP address you will want different ports to route RDP to each server. That’s a whole other lesson though.
Go to your Server Manager and Navigate to “Local Server” and click the word “Enabled” or “Disabled” next to “Remote Desktop”
Select “Allow remote connections to this computer” and check “Allow connections only from… …(recommended)” then click “Select Users”
If you haven’t already, create another non-administrator user and add that to the user list. This should be the account you use for most “checking in” type activities and you can “run as administrator” on anything that needs it. The less you use an administrator profile over the net the better.
Last, remember that port you picked? Go HERE and open it for use.
