When starting the notebook everything is ok (boot-process). Then i have to type my password on the logon-screen. The password is correct and the logon process ist starting, but after a few seconds the log-off process is starting so i can't get to the windows user interface. After the logoff-process i see again the logon-screen and can repeat the proceedure, but it is like an infinitive loop. the access to windows ist not possible, though the password is correct1 person needs an answerI do too

The Computer policy force the computer to logoff, try to logon with an administrative account. Check the computer policy.
