Carbon Black CB-Defense in combination with Ivanti Workspace Control results in a logoff

Version 7


    After logging in with Ivanti Workspace Control on a computer where Carbon Black CB-Defense is installed the session is logged off immediately after the logon is completed.

    In the Windows Event Log the following error is logged;

    Winlogon.exe crashes because of an error in ctiuser.dll which closes the user session immediately. In this case, Ivanti Workspace Control is not even able to perform a correct rundown.

    Ctiuser.dll is added by the installation of the CB-Defense agent.



    This issue is resolved in Ivanti Workspace Control 10.2.900.0.
