I’m trying to decide on the best configuration of our AD site topology after some changes to our physical network. Some of the posts on here have been very helpful but I still need some clarification on the best way to do this in our scenario.
We have 10 sites A-J, all part of one domain. Each site has one domain controller, nine running Server 2003 and one running 2008. Three of them are global catalogs. Before the change to our network, all of the sites were physically connected with each other. There was one default site link that had all of the sites in it.
Now only three sites have physical connectivity to all of the other sites, the remaining sites cannot talk to each other:
Site A, B and C can all communicate directly with all ten sites (A-J).
Sites D-J can only communicate directly with sites A, B and C.
Of course now some of the DC’s are throwing 1311 and 1722 errors because they are not able to directly talk with all of the other sites. We want to clean this up.
What is the best way to implement site links in this scenario? I know we have to turn off Bridge all site links because they do not all have connectivity with each other. We have considered the following scenarios but don’t know which one is best:
1.)Create a site link from each site to site A (hub), then create a second site link from each site to site B or C with a higher cost (in case site A goes down).
2.)Create a site link from each site to site A (hub), then create a site link bridge from each site to site B or C with a higher cost in case (in case site A goes down).
3.)Use two hubs, site A and B, with ½ of the sites each linked to one hub and the remaining sites each linked to the other hub, with a separate site link connecting the two hubs together.
What is the best way to do this?
Any help is appreciated, we are a small rural library and a support call to MS is a luxury we can’t afford at the moment.
Thanks!
