A. Windows 2000 has a whole new look for its administration tools with Microsoft Management Console (MMC) snap-ins, and for the administration of domain users the Domain Management MMC snap-in is used. This is selected from the Administrative Tools folder (Start - Programs - Administrative Tools - Directory Management)
Once started expand the domain and Users branch to see the users.
Context menus are heavily used in Windows 2000, and an example is to change a users password simply right click on the user and select "Reset Password".
Selecting Properties allows other properties of the user to be set such as group membership, profile location etc.
