Running Remote Desktop over port 443

Question

I have a server hosted behind a bunch of firewalls, and it is accessible to me only on ports 80 and 443.

The hosting company is pretty sluggish wrt support, so I would like a way to get a remote desktop to the computer.

Is it possible to install a webapp or something that would allow me to get a remote desktop via the ssl port for instance?

Solution

On the machine to connect to:

1. Start Registry Editor.

2. Locate and then click the following registry subkey:

   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber

3. On the Edit menu, click Modify, and then click Decimal.

4. Type the new port number (443), and then click OK.
5. Quit Registry Editor.

On the machine to connect from:

1. Start Remote Desktop Client.
2. Enter IP address or hostname of the target machine and append with ':443', e.g. 10.1.210.119:443
3. Continue login like usual.
