Find Operations Masters in Active Directory

Tuesday, June 1st, 2010

EDIT: I have found a much easier way to list the FSMO Roles holders.
From a command line on any domain controller, Type netdom query FSMO

Thanks to Microsoft, I have an easy solution to finding the FSMO Roles holders in a domain.

To ouput all the FSMO Role holders of a domian:

Download the file dumpfsmos.zip, extract the file, and run dumpfsmos.bat from the command line with a single argument of a domain controller.

dumpfsmos.bat MyDC01

To change any of the Operations Masters Follow these instructions.

Each FSMO Role has a diferent procedure to change the owner:

RID, PDC, and Infrastructure Roles:

From the computer that you want to make the new FSMO Role holder:

  • Open Active Directory Users and Computers MMC

  • Right-Click on the Domain Name
  • Select ‘Operations Masters…’
  • Select the tab that you would like to change
  • Click the ‘Change’ button
  • Verify that you want to change the FSMO Holder by clicking ‘Yes’

    Domain Naming Role:

    From the computer that you want to make the new FSMO Role holder:

    • Open Active Directory Domains and Trusts MMC

    • Right-Click on the Domain Name
    • Select ‘Operations Master…’
    • Click the ‘Change’ button
    • Verify that you want to change the FSMO Holder by clicking ‘Yes’

      Schema Master Role:

      From the computer that you want to make the new FSMO Role holder:

      • Open the start menu and click ‘Run’

      • Type ‘mmc’ and click ‘ok’
      • Click File -> Add/Remove Snap-in
      • Click ‘Add’, select ‘Active Directory Schema’*, and click ‘Add’
      • Click ‘Close’, then ‘Ok’
      • Left-Click, then Right-Click on ‘Active Directory Schema’
      • Select ‘Operations Master…’
      • Click the ‘Change’ button
      • Verify that you want to change the FSMO Holder by clicking ‘Yes’

      * if you do not see ‘Active Directory Schema’ in the list, you need to register schmmgmt.dll. To do this, run regsvr32 schmmgmt.dll at a command line, then re-open the ‘Add/Remove Snap-in’ menu.
