How to Quickly check FSMO roles
Active Directory contains five roles called Flexible Single Master Operation Roles (FSMO), these roles are required for the domain controllers to function correctly. During the first domain controller installation, the FSMO roles are installed automatically. In most cases they can be left alone, but there are times when they need to be moved such as a failed DC.
It is a good idea to be familiar with where the roles are installed in your AD environment, you never know when a disaster will hit. In this post, I will walk through two simple methods for finding the roles. The first method uses the Netdom query tool and the second uses windows GUI mode.
There are two forest wide roles and three domain wide roles
Forest Wide Roles:
Domain naming master
Domain Wide Roles:
RID pool manager
Method 1: Netdom query fsmo command line tool
Netdom is a command line tool used to manage Active Directory domains and trusts. The Netdom tool is built into Windows Server 2003 and up.
1. On any domain controller open the command prompt. On Windows 2012 server click the start button and type cmd, windows will search and return the command prompt. Click on “Command Prompt”.
2. From the command prompt type “netdom query fsmo” and hit “enter”.
The below command should return the five roles and which DC they are on.
That’s it for the Netdom query method, very simple and straightforward.
