Known issues in this updateSymptoms
After you apply this update on a Remote Desktop Session (RDS) host, some new users cannot connect to an RDP session. Instead, those users see a black screen, and they are eventually disconnected. This issue occurs at unspecified intervals.
The following events are usually logged when this issue occurs:
|Event Logs||Event Source||ID||Description|
|Microsoft-Windows-TerminalServices-LocalSessionManager/Operational||Microsoft-Windows-TerminalServices-LocalSessionManager||36||An error occurred when transitioning from CsrConnected in response to EvCsrInitialized. (ErrorCode 0x80004005)|
|Application||Microsoft-Windows-Winlogon||4005||The Windows logon process has unexpectedly terminated.|
During virtual channel management, a deadlock condition occurs that prevents the RDS service from accepting new connections.
To fix this issue, install November 2016 Preview of Monthly Quality Rollup for Windows 8.1 and Windows Server 2012 R2 (KB3197875).
