Remove computer from docking station
Computer Configuration\Windows Settings\Security Settings\Local Policies\User Rights Assignment
Determines which users can undock a laptop computer from its docking station.
This user right is defined in the Default Domain Controller Group Policy object (GPO) and in the local security policy of workstations and servers.
On servers and workstations, Administrators, Power Users, and Users have the right to remove a laptop computer from its docking station on computers that contain "clean installations" of Windows 2000 (that is, they weren't upgraded from a previous version of Windows). If you have upgraded the computer's operating system from Windows NT to Windows 2000, this right to remove the laptop computer from its docking station must be explicitly granted to the appropriate group or user.
