Hi and welcome to the board.

You can use runnas (note the double N) for this. If you search on runnas you will get a lot of hits.
The best option would be an admin script running from an admin system that has full access to all other system or a scheduled task. An admin script does not require a password and a scheduled task has a hidden password that is not readable for the user.
