I have a significant number of my new installations of Windows 2012 that I cannot access through RDP.
All of these servers exhibit the same symptoms.
I use the RDP client to connect to the server and after a moment I am asked form my credentials. After entering them successfully I get a black screen window in which I expect the desktop to initialize. It simply stays there for more than 20 seconds (I think much longer) and then disconnects.
Every time that happens I get an event ID Winlogon 4005. I am also receiving but not all the time event ID 6000 and 6003 referring to being unable to handle critical or normal events from AUinstallAgent.
I am not having any luck finding any cause. This happens on one of my new HP Bladeservers and on several Hyper-V guests running under 2K8R2. One of this has had nothing more than my antivirus (McAfee epo and virusscan 8.8) installed and already has this issue. Yet I have others that have NOT experienced this issue. On the one that works, it still gets the 6000 and 6003 errors.
Of three brand new installed windows 2012 servers on my hyper-v cluster, two of them exhibit this behavior and one does not. All three of these have the exact same minimally installed software.
