2.3.2.7 NTFRS Subscriber Object
Same as DFS replica sets, with the following exception.
The NTFRS subscriber object for a SYSVOL replica set is found in the domain naming context at the following RDN, within the computer's NTFRS subscriptions object:
"CN=Domain System Volume (SYSVOL share)"
Exactly one SYSVOL replica set subscriber object MUST be defined for each domain controller for every domain controller to have a copy of the domain SYSVOL.
