/DFSpath:<namespace root or DFS folder>
The namespace root or Distributed File System (DFS) folder (link) with targets for which to verify the site association.
/recurse
Enumerates and verifies the site associations for all folder targets under the specified namespace root.
/full
Verifies that AD DS and the registry of the server contain the same site association information.
/machine:<server name>
/DFSpath:<namespace root or DFS folder>
Examples
To check the site associations on machine\MyServer, type:
dfsdiag /testsites /machine:MyServer
To check a Distributed File System (DFS) folder to verify the site association, along with verifying that AD DS and the registry of the server contain the same site association information, type:

dfsrmig
Applies to: Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012
The migration tool for the DFS Replication service, dfsrmig.exe, is installed with the DFS Replication service. This tool migrates SYSvol replication from File Replication Service (FRS) to Distributed File System (DFS) Replication. It also provides information about the progress of the migration and modifies Active Dir...
Syntax
dfsrmig [/setglobalstate <state> | /getglobalstate | /getmigrationstate | /createglobalobjects |
/deleterontfrsmember [<read_only_domain_controller_name>] | /deleterodfsrmember [<read_only_domain_controller_name>] | /?]
Parameters
Parameter
Description
/setglobalstate <state>
Sets the domain's global migration state to one that corresponds to the value specified by state. You can only set the global migration state to a stable state. The state values include:0 - Start state1 - Prepared state2 - Redirected state3 - Eliminated state
/getglobalstate
Retrieves the current global migration state for the domain from the local copy of the AD DS database, when run on the PDC emulator. Use this option to confirm that you set the correct global migration state.Important: You should only run this command on the PDC emulator.
/getmigrationstate
Retrieves the current local migration state for all domain controllers in the domain and determines whether those local states match the current global migration state. Use this option to determine if all domain controllers have reached the global migration state.
/createglobalobjects
Creates the global objects and settings in AD DS used by DFS Replication uses. The only situations where you should use this option to manually create objects and settings, are:A new read-only domain controller is promoted during migration. If a new read-only domain controller is promoted in the domain after moving in...
/deleterontfrsmember [<read_only_domain_controller_name>]
Deletes the global AD DS settings for FRS replication that correspond to the specified read-only domain controller, or deletes the global AD DS settings for FRS replication for all read-only domain controllers if no value is specified for <read_only_domain_controller_name>.You shouldn't need to use this option during a...
