We have a 5 DC network that we are wanting to replace the PDC in with 2003 server. It's currently running 2000 server and it holds all the FSMO roles as far as I can tell.
We have new hardware to replace this machine and the plan is to transfer everything AD wise to another DC if needed, transfer the info on it to the new member 2003 server and then demote it and remove it from the domain and bring the other one in with the same name.
Here are my questions.
I have checked the box for one of the other DC's to be a GC but it won't update this in DNS. Under the _mcds dir in AD's DNS zone it only shows the current pdc under the GC folder. Is this normal or should the second GC show up in there? When I go into sites and services on any of the DC's the box is checked for it to be a GC.
Next, all of the FSMO roles are on the PDC at this point. Do I have to move those manually or will they automatically move when I demote it? Can I choose where they move to?
I also noticed that the replication for each DC is spread out between all the different servers. In other words each server replicates to two other servers, but not to the remaining two and each server has a different replication parteners with a few overlaps. Is this normal? Do I need to create manual connections to each of the others? The PDC is not replicating to the box I would like to serve as the PDC while I move the old box to the new one. I'm assuming it gets to it in a round about way through the other DC's that are replicating with the PDC.
