RDP Quit Working last week

We have a colo location with 4 servers.  All of the servers have allowed our staff to RDP to each server.  Last week, one server quit allowing RDP connections.  We get the following error message: "Your Remote Desktop session has ended, possibly for one of the following reasons: The administrator has ended the session., An error occurred while the connection was being established., A network problem occurred."  Since it is only one of the four servers with the problem, I assume it is not a network issue.  I can remote into the server using VNC, Dameware and ILo, so it appears to be tied to RDP.  Of course I don't want to use VNC, ILo or Dameware for our staff, so I need the RDP sessions to work.  Our GPO has the windows firewall off so I don't believe it to be a firewall issue.  
I read in one area that windows defender can disable the port used by RDP.  How can I enable this port again and how can I create an exemption in Windows defender that will prevent this from happening again.

Can you telnet to the server on the RDP port?  You should get a blinking cursor that tells you that the connection is ok.

Disable the Defender service to verify it is causing the issue.  I have never seen or ran into issues where Windows Defender was blocking access inbound on a terminal server.

If I try to telnet to our server on the 3389 port is gives me a can not connect error, but it shows the port number as 23.  So not sure what that is telling us.  The syntax I used was "telnet 19x.xxx.xxx.xxx:3389" and I hit enter.  Is this correct?  I don't see a sevice called windows defender.  Is it named something else?

Proper syntax is telnet <server IP> port.  Not :port

I am able to telnet to the server.  I am able remote connect using VNC, Dameware but not with RDC.  A screen capture is attached of the error we receive.

Gave up, called Microsoft and paid for a support ticket.  They couldn't fix it either, but about 6 days ago, it started working again.  Who knows?!?!?!?
