Cause

The system users accounts' credentials in the OS are out of sync with those in the Plesk database.

Resolution

1. Connect to your server via RDP.

2. Start a command prompt as an Administrator.

3. Synchronize system users between Plesk and the system:

   C:\> "%plesk_cli%\repair.exe" --synchronize-impersonation-storage

4. Repair system user accounts of all subscriptions:

   C:\> "%plesk_cli%\repair" --repair-all-webspaces-system-users
