When you pre-stage a computer to Active Directory using the Active Directory Users and Computers Microsoft Management Console (MMC) snap-inand you select the "This is a managed computer" option, you must type the computer's globally unique identifier (GUID).
A pre-staged system with a GUID entered in this way refers to the clients that will be using the Remote Install service (RIS) to install Windows 2000. Pre-staging ensures that only clients that have been pre-staged by the administrative staff can use this service.
When you view the GUID of the pre-staged computer, the GUID may be different from the GUID you entered.
For example, assume that you type the follow GUID:
The summary page may display the following GUID:
The GUID appears different because the first 16 bits are reversed from the order in which they were typed. This matches the representation of the GUID sent when a client boots sends its GUID to the server, and it matches the format in which the GUID is displayed when you view a client's properties.
