I'm having AD replication issues (OUs not replicating, FRS, etc) and suspect the issue is that the network admins have modified AD Sites And Services in ways that disabled the ISTG and other aspects.
Specifically, I see a number of site links, site link bridges, with varying costs that don't make sense, and seem to have been put in place to fix a problem at a point in time. (or perceived problem).
In an ideal scenario, where
- there are two hub sites
- 200 spoke sites
- none of the spoke sites can communicate with each other (with an exception or two)
What is the ideal configuration for AD replication?
What should the ISTG be set on the hub and spokes?
Should the Automatically Generated links be manually deleted?
