Test-MtAdDfsrSubscriptionCount
SYNOPSIS
Retrieves the count of DFS-R subscriptions for SYSVOL replication.
SYNTAX
Test-MtAdDfsrSubscriptionCount [-ProgressAction <ActionPreference>] [<CommonParameters>]
DESCRIPTION
Distributed File System Replication (DFS-R) is used to replicate SYSVOL content between domain controllers. Each domain controller participating in SYSVOL replication has a DFS-R subscription object in Active Directory.
This test counts the number of DFS-R subscriptions, which indicates how many domain controllers are configured for SYSVOL replication via DFS-R.
Note: Older domains may use File Replication Service (FRS) instead of DFS-R. The migration from FRS to DFS-R is recommended for improved reliability.
Security Best Practice:
- Use DFS-R instead of FRS for SYSVOL replication
- Ensure all domain controllers have DFS-R subscriptions
- Monitor replication health regularly
