I have two sites, and three servers. Site 1 has Server A and Server B. Site 2 has Server C.
All three of these servers are ADs.
I am in the process of removing Server A from the network. I have transferred all the FSMO roles to Server B. Just after doing that, I made B a Global Catalog Server (A was one already, and C is one as well).
Enough time has passed, so I want to remove the GBC setting from Server A. Just before I did that, though, something made me pause.
When in Active Directory Sites and Services:
Site 1 has Servers A and B. When looking at the NTDS settings for A, it has two objects, <automatically generated> B and C.
However, Server B only shows <automatically generated> A.
Site 2 has C. Its NTDS settings only shows <automatically generated> A as well.
It has been a few days since I checked off B as a GBS. I am not even sure if this is a problem. I guess I would feel more comfortable if the NTDS setting for B showed C, and the setting for C showed B.
I hope that makes sense. Let me know if I need to clarify, or if I even have an issue.
