Moving AD op master

mikea · Guest

I am planning on moving our win2k3 AD operations master to a new segment of
the network(at a new site). The server also does dns, dhcp, and wins for the
network. We currently have 2 sites(physical. But defined in AD as just
1)and we are downsizing to 1. We do have a backup dns as well. Just
wondering what the order of operations would be in doing this. I'm thinking
i'd want to manually change the A record in dns after it's brought up in the
new site. Then change the wins and dhcp addressess of the server to it's new
address in dhcp. Then check to see if it's synchronizing with the other
domain controllers(2). Anything else perhaps? Thanks

Assuming it only has the DC/GC role....

Possible steps to take:
* Move the DC to the other site (see:
http://www.microsoft.com/technet/prodtechnol/windowsserver2003/library/Operations/17af6280-573e-4043-9bd9-96fe3d13f4df.mspx)

* Stop the netlogon service
* Change the TCP/IP settings (IP address, DNS IP, WINS IP, etc)
* Shutdown the DC
* Move the DC physically to the other site and turn it on
* Wait at least 5 min. (the KCC runs 5 min. after the DC starts and from
that point on it runs each 15 min.)
* run on the moved DC (the W2K3SP1 version for W2K3 DCs) DCDIAG /D /V /C >
DCDIAG_OUTPUT.TXT
* run on the moved DC (the W2K3SP1 version for W2K3 DCs) NETDIAG /V /DEBUG >
NETDIAG_OUTPUT.TXT
* Open DCDIAG_OUTPUT.TXT and NETDIAG_OUTPUT.TXT and check for errors and if
any troubleshoot them

If it also has DNS role you might need to change its DNS forwarders,
delegations from other DNS servers to the DC for it DNS zones, etc. (if
applicable don't forget DNS zone specific configurations set by DNSCMD)

If it also has DHCP you need to reauthorize it. Don't forget to remove the
old authorization before shutting down the server. (through DHCP MMC -
Manage authorized servers by righ-clicking the DHCP node)

If it also has WINS role you might need to change the replication partners
that replicate with the moved DC for WINS, etc.

You might also need to change things on other servers like DNS/WINS IPs in
TCP/IP settings or even DHCP scopes, etc.

What I really mean is: what other servers have relations with the server you
want to change the IP for and WHAT and HOW is the relation?
