You don't have to work with AD for every long before you need to know or find out which domain controller is hosting a certain FSMO role e.g. Schema updates, or troubleshoot password issues etc. Luckily NetTools is able to display all the FSMO roles with just two clicks.
The Site DC List option in NetTools will display the FSMO roles for all the domain controllers in the forest.
Key for the Roles:
G - Global Catalog
D - Domain Master
I - Infrastructure Master
P - PDC Master
R - RID Master
