Known issues in this updateIssue 1
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).
When a service such as Exchange server tries to reestablish the Kerberos client session during a cluster failover, it may cause the system to become unresponsive. Additionally, an LSASS CPU spike occurs after the failover.
ResolutionMicrosoft Windows has released a fix that contains new opt-in behavior for the Kerberos client to address this issue. By enabling the Kerberos parameter, the Kerberos client can bypass the CPU intensive action of purging compounded tickets.
Note The Kerberos client must opt-in for the new behavior. Follow these steps to create the registry parameter on each node of the cluster:
- In Registry Editor, locate and then select the following subkey:HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa\Kerberos\Parameters
- Right-click Parameters, point to New, and then click DWORD Value.
- Type AllowStaleDeviceAuthzData as the entry name, and then press Enter.
- Right-click AllowStaleDeviceAuthzData, and then click Modify.
- In the Value data box, type 1, and then click OK.
