Good Day -

I have a W2K3 DC that has a failed HDD. I've gracefully transferred all roles and want to decommission it and introduce a W2K8 R2 DC. I've already introduced the first W2K8R2 DC so the forest and domain have been prepped (6 months ago)

This DC is also a DNS server and there are a lot of hosts that have this as their primary DNS server set manually. For that reason, I'd like to bring up the new DC with the same IP, does the following sequence of steps appear accurate?

Bring up new w2k8 r2 box, patch and add to domain
DCPROMO 2K3 DC
remove from the domain and turn off.
change IP of wink28 r2 box to same IP as previously decommisioned w2k3 DC)
DCPROMO W2K8 R2 server(different computer name)
Make sure DNS zones and records are populated and transferred, configure respective forwarders and other DNS settings.
test replication: repadmin /replsum ?

I'm curious if there should be a period i should wait for AD replication could recognize and remove the decommissioned W2K3 box.

Looking forward to your feedback.

Best,

H

Once the 2003 box is gone, I'd force replication both on the configuration naming context and the domain.

Double check that all of the SRV records that refer to the server are all gone from DNS.

Should work!

Thanks for the reply Mark!

I know there is a repadmin gui these days but call me old school -- what's the repadmin syntax for jus the config naming context ?

repadmin /syncall /e /P <name of dc> DC=domain,DC=org ?

repadmin /syncall /e /P <dcname>

Simple as that... believe it or not the config NC is the DEFAULT!

1. Configuration NC default

quote:
repadmin /syncall /e /P <dcname>

Simple as that... believe it or not the config NC is the DEFAULT!


So, in a single site scenario, using the default "pull" replication (we pull changes from others domain controllers to the one we're at):

repadmin /syncall DC1

????

If so, that's "short and sweet".

2. /P

That parameter would be used if we wanted to PUSH changes TOWARD the other domain controllers. OK.

3. /syncall versus /replicate

If you wanted to force replication, why use one parameter rather than the other?

http://technet.microsoft.com/en-us/library/cc773062(v=WS.10).aspx

*

/replicate = initiate replication with a single (the designated) DC?

/syncall = initiate replication with all replication partners?

*

Looks like if you had two domain controllers, there would be no difference.

4. REPADMIN GUI?

I thought that was REPLMON - which ceased to exist with W2K8?

Unless I've missed something in R2, I think you have the choice of certain options in ADSS (Sites and Services) or the command line (repadmin).

REPLMON is gone, right? Or has it made a reappearence?
