Windows

Put your Exchange 2000 Server CD into the the workstation you will be using to administer Exchange. When the installation popup comes up, run Exchange Server Setup, follow the install path until you get to the component selection and under Microsoft Exchange System Management Tools, select Microsoft Exchange 5.5 Administrator. Only select this, nothing else. You can do this on any DC's on the network also to give them the ability to create mailboxes for user accounts, etc.
