I'm trying to sort out my domain controllers in Sits and Services. I'd discovered recently that a subnet has been tied to our HQ site when the subnet network is actually at an offiste location where those servers/VM's are as well. So I don't think that has been optimal over time.
My concern/question is, should the Domain Controllers I move from the HQ site to the other site cause a problem, and changing the changing the site association for the subnet to that proper site, affect logging in?
I created a "Site Link" between these two sites. But there is also a "DEFAULTIPSITELINK" that contains ALL OF the sites, which I'm not sure is needed, optimal, or can be deleted.
This would be mostly server 2008 R2 environment, with a couple 2012 R2 DC's.
