Description

The User logoff process is stuck while processing the WMIPrvse and PicaDm

Environment

Caution! Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.

Resolution

The below registry helped us to resolve the issue. Key : HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\picadm\Parameters Name : RequestTimeout Type : DWORD Value : 3 (decimal)

Problem Cause

The Winlogon process is waiting on an ALPC call with WMI and WMI is processing the Office16 and this calls into PICADM, which is a network redirector driver. The thread is blocking with the MPXWait() which was causing the logoff issues

Additional Information

The memory dump should show the Winlogon thread waiting on WMIPrvse which in turn is blocked in PicaDM...
