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
