SUMMARY

The File Replication Service (FRS) is a multi-threaded, multi-master replication engine that replaces the LMREPL service in Microsoft Windows NT 3.x and 4.0. Windows 2000 domain controllers and servers use the FRS service to replicate system policy and login scripts for Windows 2000 and down-level clients.

Optionally, the FRS service can replicate content between Windows 2000 servers hosting the same fault-tolerant Distributed File System (DFS) roots or child-node replicas.

This article discusses setting file and folder filters for the system volume (SYSVOL), DFS root, and DFS child nodes.


MORE INFORMATION

Overview

File and folder filters are managed by the FrsFileFilter and FrsFolderFilter attributes of the NTFRS-Replica-Set class.



File and folder filters are maintained for each FRS replica including the following:
  1. SYSVOL (Note 1)


  2. Fault tolerant roots where replication has been enabled note 1).


  3. DFS child nodes residing on Windows 2000 servers where replication has been enabled (note 2).


Note 1: Replication for SYSVOL is implicitly enabled.

Note 2: DFS repliation must be enabled in the Distributed File System Manager snap-in (DFSGUI.MSC) on levels of the DFS namespace "backed" by more than one Windows 2000 server. No user interface exists to modify file and folder filters but both attributes can be modified directly in the Active Directory directory service from an editor such as ADSIEDIT.MSC or LDP.EXE (Microsoft Windows 2000 Resource Kit utility). The following steps illustrate setting a file filter first for SYSVOL, and then for a DFS root on a domain controller in the A.COM domain.

SYSVOL File and Folder Filters


  1. Start the LDP.EXE tool. Complete the connect and bind sequence using an account with administrative privledges.


  2. On the View menu, click Tree.

    1. Type the full DN path for the domain: CN=Domain System Volume (SYSVOL share),CN=File Replication Service,CN=System,DC=A,DC=COM


    2. Type the corresponding path for the domain starting from the root, DC=A,DC=COM, and then double-click through the DN hierarchy to reach the path above.




  3. Right-click the DN path in the left pane, and then click Modify.


  4. In the Modify dialog box, the DN field path should have the path used in step 2. In the Attribute box, type FrsDirectoryFilter or FrsFileFilter. In the Values box, type the desired filter extension (for example, *.tmp). Multiple extensions can be defined using a comma (,) as a delimiter (for example, *.tmp,*.bak,*,bat).


  5. Press ENTER to add the filter parameters to the Entry list, and then click Run.


  6. Double-click the DN path in the left pane to refresh the screen.


DFS File and Folder Filters

These steps illustrate how to set a file filter for a DFS root named "DFSFT" on a domain controller in the A.COM domain.

  1. Start the LDP.EXE tool. Complete the connect and bind sequence using an account with administrative priveledges.


  2. On the View, click Tree.

    1. Type the full DN path for the domain: CN=DFSFT,CN=DFSFT,CN=DFS Volumes,CN=File Replication Service,CN=System,DC=A,DC=COM. The objectClass in the right pane should be "nTFRSReplicaSet."


    2. Type the corresponding path for the domain starting from the root, DC=A,DC=COM, and then double-click through the DN hierarchy to reach the path above.




  3. Right-click the DN path in the left pane, and then click Modify.


  4. In the Modify dialog box, the DN field path should have the path used in step 2. In the Attribute box, type FrsDirectoryFilter or FrsFileFilter. In the Values box, type the desired filter extension (for example, *.tmp). Multiple extensions can be defined using a comma (,) as a delimiter (for example, *.tmp,*.bak,*,bat).


  5. Press ENTER to add the filter parameters to the Entry list, and then click Run.


  6. Double-click the DN path in the left pane to refresh the screen.


The DN path for a replicated DFS child node called "MyTools" is "CN=DFSFT|mytools,CN=DFSFT,CN=DFS Volumes,CN=File Replication Service,CN=System,DC=A,DC=COM." Again, the objectClass is "nTFRSReplicaSet".
