I'm unable to connect remotely to one of a number of servers on the network running 2012 R2 using the Windows RDC client.
Here is the error:
So far I've done the following:
- Ping the server in question. Connectivity = fine.
- Checked Remote Desktop is enabled (system properties > remote > allow remote connections to this computer)
- Windows firewall is currently turned OFF for all profiles (domain, private, public)
- telnet from another machine on the network to the server on port 3389: I just get a blank cursor, no connection
- run netstat -o -a to check the server is listening on port 3389. It is, see below:
TCP 0.0.0.0:3389 servername:0 LISTENING 3236
- I have also run qwinsta to check the RDC service is listening, see pic below:
- I have rebooted the server, checked firewall on the client (and tested from multiple clients)
- Nothing in event logs
- I have changed the listening port (regedit > hklm\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp port) and done all of the above, same happens. netstat shows the node is listening on 3390 but can't connect by RDC client or telnet on that new port.
I followed this unusually thorough article on support.microsoft.com (despite it seems to refer to Server 2003) to troubleshoot further.
I'm concluding that I should somehow find a way to blat the RDC service and rebuild it. Is that possible?
