SYMPTOMS
If you use the System Preparation Tool for Windows NT 4.0 to duplicate a Windows NT installation from one computer to another, the Security Identifier (SID) values for local user accounts are changed, but the SID values for built-in local groups are not changed.



CAUSE
This behavior occurs because the Relative Identifier (RID) value for built-in local groups is the same across all duplicate installations of Windows NT. Only the SID values must be unique for all newly created users and groups.



STATUS
This behavior is by design.



MORE INFORMATION
The default built-in local groups include the following:


 * Administrators
 * Backup Operators
 * Guests
 * Power Users
 * Replicator
 * Users

For more information about SID and RID values, please see the following article in the Microsoft Knowledge Base:
