SymptomsUnable to login to container by RDP even Terminal server is running, port 3389 port is not listened. There are no any firewalls or IPSec polices enabled. No any error in container Event Log (if we connect remotely)
CausePossible reason of such behavior could be that the service “Terminal Server Device Redirector” was disabled in Computer management, Device manager, System Devices.
ResolutionWhen disabling ANY device in this snap-in the following key created:
HKEY_LOCAL_MACHINE\vzXXXX\MACHINE\SYSTEM\ControlSet001\Hardware Profiles\0001\System\CurrentControlSet\Enum\ROOT\***SERVICE NAME*** \0000
CSConfigFlags DWORD Value 1
***Service NAME** is real (not displayed) name of the service. For “Terminal Server Device Redirector” it is RDPDR
After the next reboot CurrentControlSet001 is moving in CurrentControlSet and device is disabled.
To fix the problem it is necessary to change
CSConfigFlags DWORD Value to 0
and restart the container.
The same is actual for all disabled\enabled devices.
