Ok, today I locked-out myself from one of my dedicated servers.. how? I changed the RDP-Port in the Registry:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp And then, I FORGOT to add the new Port to the so called ‘Windows Firewall with Advanced Security’ .. it was like a lighting strike in my body when I clicked ‘restart Server’…
