Root Cause: This issue can occur in an Orchestrator environment when a registry key is not properly updated.

Resolution: The following are the approaches for a fix,

Approach #1: Do not log on to the server for interactive sessions by using a service account.

This prevents potential issues with registry keys and profiles that can arise when service accounts are used for interactive sessions.

Approach #2:

  1. Disable the related Windows User Profile Service feature. To do this, follow these steps:
  2. Open the Group Policy editor (Gpedit.msc) on the affected server.
  3. Open the UserProfiles folder in the following path:
  • Computer Configuration > Administrative Templates > System > UserProfiles
  1. Locate the Do not forcefully unload the user registry at user logoff setting
  2. Change the setting to Enabled.

This setting prevents the user registry from being forcefully unloaded, which can help avoid issues with registry keys.

Approach #3:

  1. Run gpudate and gpupdate /force and then restart the affected server
  2. Running these commands updates Group Policy settings and forces a refresh, which can resolve issues related to policy application and registry keys
  3. Restarting the server ensures that all changes are properly applied and any lingering issues are resolved.
