Logon Prompt Extension deployment problems

Problem​

Logon Prompt Extension is not being deployed via GPO.

There could be several different reasons for this issue. You must collect additional information to support the investigation.

Resolution​

To investigate further, enable GPO software installation logging as described in the Microsoft KB article: http://support.microsoft.com/kb/249621

Follow these steps on the problematic client computer:

  1. Launch regedit and navigate to the following key:

    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Diagnostics
    • You may have to create the Diagnostics registry subkey if it is not present.

  2. In the Diagnostics key create a new value:

    • Type: DWORD
    • Name: AppMgmtDebugLevel
    • Value: 4b (HEX)

  3. Reproduce the issue — try to install the Logon Prompt Extension via GPO.

  4. Create a new ticket on our site (https://www.netwrix.com/support_ticket.html) and send the diagnostic file:

    • %SystemRoot%\DebugUserMode\Appmgmt.log

NOTE: We recommend that you delete the AppMgmtDebugLevel registry value to avoid performance degradation after sending the log files to us.
