Domain Replication Issues

Hi All,
Not sure if this is quite the right forum, but it's the closest one I could find.

Kind of a newb to the whole Active Directory thing on windows 2000 server, so be gentle :)

We've got a large world-spanning network with a master domain here at home office.  Each of the 15 other locations is a child domain off of this master.  In our domain replication logs for each server, there are a lot of Event ID 1265 "RPC unreachable" errors.

The thing is, I don't want the child domains to talk to anyone but the daddy; our VPN won't allow them to, they're not explicitly set to trust one another.  Is there a way to stop KCC from trying to get these guys to talk?  (a lot of wasted network traffic and troublesome looking error messages - probably some other crap I'm not aware of too)

As always, information for the greenhorn is much appreciated.

well actually as these domains are in the same forest they would have to talk to each other either directly or through some other domain controller to replicate GC information, schema and configuration. they would trust each other because they are in the same forest, if you stop them from replicating then they would be orphaned and would not replicate after 60 days (tombstone) . If you want that the child domains should only replicate with the root domain in the forest thats fine because the other domains would get the replication info through the root.

what KCC does is it generates the replication topology through one of its components called the ISTG, if you disable KCC then you would have to manually configure the connection objects for the DC's to replicate also if there is a new site created you would have to specify the bridgehead server.
reason why replication is best left to KCC is because if a bridgehead server in a site goes down then its KCC who would automatically elect a new bridgehead server.


disable KCC
