If you are getting a lot of Event Id 1030 errors that appear in the event log like “Windows cannot query for the list of Group Policy objects”. I recommend you remove badly stored domain credentials via the registry.

1. Run Regedit
2. Drill down to HKLM\System\CurrentControlSet\Control\Lsa
3. In the right pane locate the disabledomaincreds key
4. Change the disabledomaincreds value to 1 to stop store domain credentials.
