RDS Broken after Virtual Machine reconfiguration






After migrating a few virtual machines across datacentres (using vConverter in this instance, but the same error could occur with any type of VM configuration, specifically when adding and removing virtual NICs), I was no longer able to RDP a server previously configured with Remote Desktop Services (RDS). I actually forgot to screenshot the RDP error, but it was “Remote Desktop can’t connect to the remote computer for one of these reasons: 1) Remote accces to the server is not enabled 2) The remote computer is turned off 3) The remote computer is not available on the network.  Make sure the remote computer is turned on and connected to the network, and that remote access is enabled.”

On the affected host, navigate to RDS Administration (Start > Admin Tools > Remote Desktop Services > Remote Desktop Session Host Configuration:

Right-click the RDP-Tcp connection & select Properties:

RDS1

The error message is displayed when switching to the Network Adapter tab:

RDS2

“Remote Desktop Session Host Configuration tool is not able to obtain the properties for this connection. The connection has either been deleted or the internal state of this connection has been corrupted. Please close all property pages, and select refresh from the menu.”

You can see here the defined Network Adapter is missing completely, but can’t be changed:

RDS3

Start Regedit and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp

Set the ‘LanAdapter’ value to 0

Restart RDS services or server, and retry RDP!

RDS4
