Here is how I got around it. From a command prompt on my PC or another computer on the domain I ran this to find out the PID of the svchost.exe associated with SENS
sc \servername queryex SENS
Then I kill that process with this command
taskkill /S servername /PID xxxx /F
where xxxx is the PID from the first command.
Now I can connect to the server with RDP and I didn’t have to restart the server.
Obviously this is not a fix for the actual problem, but it lets you log on to your server.
