How to find the global catalog of my network in ADDC?
I'm learning IT right now, and I have this situation.
The employee who was the administrator, got out of the company. But he doesn't leave a documentation to tell me which of my ADDC (Active Directory Domain Controller) is the PDC, I mean I'm interested to fin the global catalog and structure of my network.
Does you know a post from TechNet or some site to find this PDC in Windows Server 2008 R2?
Answer
You can either open Active Directory Sites and services, expand sites -> servers and look at the NTDS settings of each server you have, there will be a tick box on the general tab that will be checked if the server is a global catalog.
Alternatively, if you have quite a lot of servers and don't want to have to do this for each one, you can use nslookup:
Find a list of global catalogs using nslookup
As for PDC though, these haven't really existed since windows NT, there is however a PDC emulator FSMO role which is held by one domain controller that you can find using the following command:
dsquery server -hasfsmo pdc
You can see the other FSMO roles here:
