Windows server 2012 not full rights?

Question

Access rights

Good afternoon, the account was crooked on the windows server 2012 machine and now the administrator does not have full rights, you need to restart the machine manually, but there are not enough rights to do this, what can be done to raise its privileges or is it better to demolish and install the server on a new one? Thanks

Answer 1

If WS is still empty, then it's easier to reinstall
