Whether the backup domain controller contains MD5 checksum data to source the Sysvol tree

Hi,

I'm documenting a procedure to do a system state backup of our 2003 Domain.  During that process I've run into a question as to how to name the backup .bkf file.   The following Microsoft Article Documents this at
http://technet.microsoft.com/en-us/library/cc785766(v=ws.10).aspx

For naming the bfk file, one of the considerations is to know

Whether the backup domain controller contains MD5 checksum data to source Sysvol Tree.

Does anyone know how or where I would go about where to check this setting in Active Directory?  Is is visible on a Domain Controller?

Thanks,

Kevin C.
