Windows auditing

["eric" <fengjie () pacific net sg>]

The auditor requested us to supply all the domain users who have local
administrator's right to their machines. Is there a way better than going to
each machine to check it out? We have 600+ users/machines!
I am currently using a tool called Hayena, which gives me a
windows-explorer-like view of all domain computers but doesn't save me from
having to go to every computer folder to check from local groups.
Your help is greatly appreciated.

Regards
Eric
