I have several servers running Windows Server 2012 R2. These servers are used for testing, and are members of a domain which has two DCs, each of which are running DNS Server.
Yesterday I noticed one of the servers was having an issue with its remote desktop connection. If I try remoting into this machine, it connects to a black screen, sits there for 2-3 seconds and then promptly disconnects. No error message is given. I tried this from a couple different Windows 7 machines, and got the same result. I tried from my wife's iMac, which runs Jump Desktop, and too was met with the same result.
I can, however, remote into this machine via RDP from my work-issued laptop, which is running Windows 8. However, I cannot remote into the problem machine via Remote Desktop Connection from one of the 2012 R2 servers--I am met with the same result as the other machines: connect, black screen for 2-3 seconds, disconnect without error.
I can remote into all of the other 2012 R2 servers without issue from any machine, including the iMac. I am experiencing this problem on one server only.
Since it is a test server, I reinstalled Windows from scratch this morning. This meant formatting the SSD and wiping everything out. I reinstalled the drivers, joined the server back to the domain and installed all of the updates available from Windows Update. And rebooted. And yet, the problem persists!
I tried troubleshooting the "usual suspects," like turning off Windows Firewall, disabling antivirus software (currently none installed), disabling IPv6, setting a static IP instead of using DHCP, etc. I did notice the network adapter said it was on a Network, not a Domain Network. I corrected DNS settings, and the network reidentified itself as being on the ParietalBone.net network. And yet, the problem persists. Remote Desktop to this server still yields a black screen for 2-3 seconds, followed by a disconnect--EXCEPT from the aforementioned Windows 8 machine.
I looked in the TerminalServices-LocalSessionManager log on the offending server, and there are no errors. I only see repeated entries that say "Session X has been disconnected, reason code 12," where X is 1 or 2. On a couple occasions, the reason code is 11. But I don't see any errors indicating a breakdown in security negotiation.
Without any robust logs or debug details, I'm at a loss of where to look for a solution.
