Hello together,
Recently we start experiencing a strange problem with one of our Terminal servers. Shortly i will describe you, what exactly happen and how exactly the problem occur.
1. Our server is Terminal server Windows 2012 R2.
2. From location (not constant one) user bring up a VPN tunnels over SSL through NetExtender SonicWall app.
3. After short period of time, without any reason VPN terminate the session and the RDP session goes down likewise.
4. Immediately, the user restore the VPN session without any problems, but here the problems starts.
5. After login issues.
5.1 If the user use normal mstsc (RDP), logon screen appear, with domain\username field, etc,. but the password field is inactive, username field, language change button, everything else on the screen is also inactive.
5.2 If the user change his session to use Microsoft Remote Desktop Connection Manager instead of normal RDP (mstsc), the session start, normal desktop and all icons on it appear, but again without any options they to be selected, or chosen
or do anything instead watching the frozen screen.
5.3 If the user use, another user (username) which was not previously used (there is no active session in disconnected or other state for the new user), RDP start but everything goes black (black frozen screen).
The only one option, someone to be able to use the server, is to open VMWARE, and from there to start the console. The only think what solved the issue, when it is occur, is to restart the server.
All investigation shows that error as EVENT ID (Event ID 9009 - The Desktop Window Manager has exited with code (0xd00002fe)).
Please for your help. Thanks in advance.
Best Regards.
