(http://support.microsoft.com/kb/256986/ )Description of the Microsoft Windows registry
This article describes how to avoid duplicate globally unique identifiers (GUIDs) when you use disk imaging or cloning to deploy the Microsoft Systems Management Server (SMS) 2003 clients.
In SMS 2003, all clients are uniquely identified by a GUID. A GUID is a combination of the client's media access control (MAC) address and the time when the GUID is assigned. This combination produces a number that is virtually always unique. The GUID assignment occurs during the SMS 2003 client discovery and installation processes.
The GUID is stored in the client's Registry and in a binary file on the client's hard disk. Many problems in an SMS 2003 environment may occur if more than one SMS 2003 client has the same GUID. The whole site may even be disabled. If you use disk duplication software, you must make sure that SMS 2003 client GUIDs are not duplicated during copying or imaging.
To duplicate a disk, you create a master image from a host computer, and then you deploy (or copy) the master image to other computers. Disk duplication makes sure that each computer's operating system and program settings are the same. The SMS 2003 Legacy Client and the SMS 2003 Advanced Client use different methods to avoid the duplication of GUIDs when you duplicate hard disks for the SMS 2003 client deployment.
Preparing the SMS 2003 Legacy Client computer for imagingWarning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
To prepare the master-image computer for duplication and to avoid duplicate GUIDs for the SMS 2003 Legacy Client:
Preparing the SMS 2003 Advanced Client computer for imagingYou can prepare SMS 2003 Advanced Client computers for imaging when you install the core SMS 2003 Advanced Client components on the master-image computer without specifying an SMS 2003 site code for assignment. All computers that are imaged later from that master image will contain the Advanced Client core components without a site code. However, the imaged computers will not be functional SMS 2003 clients until the SMS 2003 clients are assigned to an SMS 2003 site.
To prepare the SMS 2003 Advanced Client computer for imaging:
