Admins Handbook

If you for some reason need two RDP-Tcp connections in Windows 2008 you could easily add one in the “Remote desktop Session Host Configuration” tool.

This tool does not exist in Windows 2012 and you have to do it with regedit.
Make an export of this:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp

Edit this regfile and change the path
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp-3390

This will be your new RDP-Tcp connection.
Change “LanAdapter” to the listening netcard
0 = all
1= netcard1
2=netcard2
3=netcard3

Change “PortNumber” to the port listening on the RDP-Tcp-3390
In this way, the original RDP-Tcp could listening on port 3389 with netcard1 and RDP-Tcp-3390 listening on port 3390 with netcard2

Show netcard ID:
netsh interface ipv4 show interfaces

Show assignments in powershell:
gwmi Win32_TSNetworkAdapterSetting -filter “TerminalName=’RDP-Tcp'” -namespace “root/cimv2/TerminalServices” | Select NetworkAdapterLanaID,NetworkAdapterName
and
gwmi Win32_TSNetworkAdapterSetting -filter “TerminalName=’RDP-Tcp-3390′” -namespace “root/cimv2/TerminalServices” | Select NetworkAdapterLanaID,NetworkAdapterName
