Resolution
This is fixed in version 11.2.2 - see KB 7010757 "ZENworks Configuration Management 11.2.2 - update information and list of fixes" which can be found at https://support.microfocus.com/kb/doc.php?id=7010757
This is partially fixed in version 11.2 - see KB 7010044 "ZENworks Configuration Management 11.2 - update information and list of fixes" which can be found at https://www.novell.com/support
Some customers still experience the issue after applying 11.2 and those cases are under investigation.

Some customers still experience the issue after applying 11.2 and those cases are under investigation.
Workaround: if it is not possible to upgrade to 11.2 at this time, in the interim, Novell has made a Patch available for testing, in the form of a Field Test File (FTF): it can be obtained at https://download.novell.com/Download?buildid=27T5PItrmO8~ as "ZCM 11.1 fix for RDP session crash - see TID 7009593". This Patch should only be applied if the symptoms above are being experienced, and are causing problems.
This Patch has had limited testing, and should not be used in a production system without first being checked in a test environment. Some Patches have specific requirements for deployment, it is very important to follow any instructions in the readme at the download site. Please report any problems encountered when using this Patch, by using the feedback link on this TID.
Workaround:1) On the device that is launching the RDP session, in the registry, change (or create if it does not exist) the DWORD
HKLM\SOFTWARE\Novell\Authentication, "EnableStatusMessages" and set the value data to "0" as seen in the documentation " Disabling the Login Status Messages Display on the Device Screen" at https://www.novell.com/documentation/zenworks11/zen11_system_admin/data/bbtsocd.html#btwuk3b
or
2) Alternative workaround: On the target device, run tsconfig.msc, right-click on "RDP-Tcp" in "Connections" and choose "Properties".
Change "Security layer" from "Negotiate" to "RDP Security Layer", then click "OK" - see http://technet.microsoft.com/en-us/library/cc781085%28WS.10%29.aspx (W2K3) and http://technet.microsoft.com/en-us/library/cc770833.aspx (W2K8) for information about the various security levels; any changes to security should be understood before deployment.
or
3) Alternative workaround: if the User Management component of the ZCM agent is uninstalled from the device that starts the remote session, the problem does not occur. This would mean that user-assigned bundles and policies would not be available on this device.
