A. When you perform a backup and include the system state, the information the OS includes in the backup will vary depending on the type and state of the machine. The following table lists the elements the OS backs up:
|Element to be Backed up||Domain Controller||Non-Domain Controller|
|Active Directory (NTDS)||Yes||No|
|System Volume (SYSVOL)||Yes||No|
|COM+ class registration database||Yes||Yes|
The OS will back up information about certificate services regardless of domain controller (DC) status.
