Hello,
I have three existing domain controllers in two sites. DomainController1 and DomainController2 are in SiteA. DomainController3 is in SiteB. I just added a new DomainController4 to SiteA. When I look at NTDS settings for SiteB it only has connection to DC1 and DC2, not the new DC4. I also noticed that only DC1 in SiteA has the NTDS connection to the DC3 which is in SiteB so maybe this is all good? I just want to know if I need to creat a new NTDS setting connection for the newly promoted DC4 to DC3. I am thinking I only need one intersite connection?
