AD - FSMO Roles (Quick Guide)

Active Directory FSMO (Flexible Single Master) Roles.

Microsoft's best practise advice you not to put the Global Catalog Role on the DC that holds most of the FSMO Roles. Always put the Global Catalog on another server.

AD Installation Wizard (DCpromo.exe) defines 5 FSMO Roles:

1. Schema Master
2. Domain Naming Master
3. PDC Emulator
4. RID Master
   
5. Infrastructure Master (for each respective domain)

To inspect FSMO Roles:

Run "dsa.msc" (AD Users and Computers) right click on domain



Click on Operations Masters to view Roles
