Adding a computer to a server is accomplished through the Windows Active Directory Service. This application allows network administrators to add users, computers, and print resources to the network. Active Directory is the central console for a majority of the security on a Windows server. Adding a computer to the network only takes a few steps in the application console on the server.
Click the Windows "Start" button and select "All Programs." From the menu, select "Administrative Tools" and choose "Active Directory Users and Computers."
Right-click the "Computers" icon listed under the server's domain. Select "New" and then "Computer" from the menu. A configuration window opens to add the new computer.
Enter the name of the computer to add and click the "Next" button.
Click the "Finish" button at the summary screen. Reboot the computer that was added to Active Directory. The user of the computer can now log on to the domain server.
