Add a Computer Account
To perform this procedure, you must be a member of the Account Operators group, the Domain Admins group, or the Enterprise Admins group in Active Directory, or you must have been delegated the appropriate authority. As a security best practice, consider using Run as to perform this procedure.
 * 1) Click Start, point to Programs, point to Administrative Tools, and then click Active Directory Users and Computers.
 * 2) In the console tree, click Computers under the domain node, or click the container in which you want to add the computer.
 * 3) Right-click Computers or the container in which you want to add the computer, point to New, and then click Computer.
 * 4) Type the computer name.IMPORTANT: The Default Domain Policy settings allow only members of the Domain Admins group to add a computer account to a domain. Click Change to specify a different user or group that can add this computer to the domain.

NOTES:
 * 1) * To view or change the full computer name of a computer and the domain that a computer belongs to, right-click My Computer on the desktop, click Properties, and then click the Network Identification tab.
 * 2) * There are two additional ways to give a user or group permission to add a computer to the domain: use a Group Policy object to grant the right Add computer user, or, for the organizational unit in which you want to allow them to create computer objects, grant the user or group the permission to create computer objects.
 * 3) * If the computer that is using the account that you are creating is running a version of Windows earlier than 2000, click to select the Assign this computer account as a pre-Windows 2000 computer check box.
 * 4) * The Assign this computer account as a pre-Windows 2000 computer check box assigns a password that is based on the new computer name. If you do not select this check box, you are assigned a random password.
 * 5) * If you intend to use the computer with the newly created account as a backup computer for a domain controller, click Assign this computer account as a backup domain controller.
