to use my username to log on as administrator at any computer instead of be using the administrator account !

it wont eve give you chance to login into the computer,
and is jus that specific user. i can loging using my account without any issue.
is just that specific user.
there will be something wrong with the user it self ?

Answer : specific user to be DC ADMIN

It could be that somehow he does not have local logon rights.

I would check that

also, I would check if that happens on another machine, not just his own.

I hope this helps !
