Hi,
What related event error can you read in the Event Viewer?
Please perform the following steps on these two clients:
Delete All Group Policy Registry keys
========================
1. Click “Start”, type “regedit.exe” (without quotation marks) into “Start Search” box and press Enter.
2. Locate the following key:
[HKEY_LOCAL_MACHINE\Software\Policies\Microsoft]
Right click on "Microsoft", click "Export"; please name the file as "RegBackup" (without quotation marks) and then save it to the C:\ drive as a backup.
Note: In case we need to undo the modification, we can double click this RegBackup.reg file to restore the registry key.
3. Highlight Microsoft and click "Delete".
4. Please repeat the above steps for the following registry keys.
[HKEY_CURRENT_USER\Software\Policies\Microsoft]
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Group Policy Objects]
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies
Note: if some keys do not exist, please ignore them.
3. Exit the Registry Editor.
After that, restart the computer to reapply the Group Policy to check the result.
