RE: [ActiveDir] GC Promotion
Title: RE: [ActiveDir] GC Promotion Hi, Jorge, We’re talking in the context of an AD replication site. If it were picking writeable anywhere, then yeah, that would not be good for network utilization unless you’re a provider and charge by the bit. The point is that in a site, the writeable copy of a partition is potentially higher fidelity than any of the read-only copies. The KCC must take the write-ability of a partition into account when it’s working out the topology since it at least has to make sure the writeable copies all replicate amongst themselves.

Re: [ActiveDir] GC Promotion
I've got a parent-child domain setup here and I have child domain GCs which repls the parent domain NC from another child domain NC. Now I dont know if its possible to make a GC using a DC of the other domain thats not a GC. In a hypothetical setup where all sites were not fully routed this could be tested, forcing it to repl NCs from a site/server that has/is no GC. But I wont be testing that in a VM in the near future. I'll let the knowledgable enlighten us on the subject.

RE: [ActiveDir] GC Promotion Problems
Joe- They were originally marked as GCs before the import sometime last week. They logged the 1119 event and between then and now many of them had been rebooted (perhaps not all). I checked the RootDSE this morning and saw that they weren't, and observed the search issue. So, I unchecked them all, waited a while (couple hours), and then went back in and re checked off the GC box. Since then I have not rebooted any of them. --Brian -Original Message- From: joe [mailto:[EMAIL PROTECTED] Sent: Tue 8/10/2004 5:31 PM To: [EMAIL PROTECTED] Cc: Subject: RE: [ActiveDir] GC Promotion Problems I read your post to say, Hi, I got the 1119 but the GCs are responding as GCs even though the RootDSE says they are.
