Hi, I am facing a similar problem. We are suddenly unable to logon to WinCC runtime (Giving unknown user message) and we can not create create anymore users in Explorer (Internal Error: Project could not be opened, User administrator failed; Error on reading permission levels). Surprisingly, the operations are possible without even logging in. Any idea what could be wrong? ------------------------------------------------------------------------------------------ |
