Help Pls Emergancy?

am in a lot trouble.
In my win2003 domain based network. when i goes to workstation machines and access and administrative share from that machine with my admin user name and password during the logged in my network users session, the share can be accessible.
But i want to know that is there any method so that when i close the share which was access by admin user name and password, then the logged in user can not be able to open it without logging off his account.
