client assignment in AD DS sites
Posted on 2011-09-27
We have 3 sites:
Sites A and B contain domain controllers, and both have subnets defined for them in Active Directory Sites and Services. Site C has no servers or subnets defined for it. Clients are associated with Site C. These clients are also on subnets that are not defined in any site. Is this why they are associated with Site C? How are clients that are on a subnet not associated with any site becoming associated with a site? Does this occur based on link cost and closest DC by hop count?
I'm curious about all of this, b/c clients in Site C are having some GPO replication problems from time to time, and I'm trying to track that down. Since Site C is defined in AD DS, but it has no subnets, and has no servers, I'm a bit confused about how GPO replication is occuring, and what DC they should be getting it from by default. I'm also trying to determine what the point of a site is if there are no subnets associated with it.
I know there is copius information on this topic doing a simple google search, however, I struggle from time to time finding concise information specifically regarding what I'm curious about which is why I'm here.
