DC Rebuild

Hi,

I'm in the process of rebuilding a child DC. I created a
replica and I want to do the changeover shortly. Before I
change them over is there anything I need to take into
consideration?

Should I backup the current DNS configuration and import
it to the new dc?

Also, I have changed the name of the new DC. What to I
need to do in sites and services, if anything?

Any help and links are greatly appreciated,
 
Transfer the FSMO roles (link to KB article further down) then use Xcopy to
move the data. Change the DNS settings on the DHCP scope (if you use DHCP
that is) so that your
clients will get the new DNS Server's IP address, temporarily change the
lease time so they get the new settings before you uninstall the old DNS,
then change it back when you verify that they do lookup on the new DNS.

The easiest way (IMHO) is to integrate the DNS to AD on the existing server,
install DNS on the new one and give it time to replicate. Then you can
uninstall the old DNS and change the new DNS to Primary if you want.
See URL below on how to move the DHCP database. Install a second WINS on the
new server, configure DHCP to point the clients to the new server (same
procedure as DNS above).

Hi Jimmy,
Click to expand...

Thanks for the mail....

Server in question does not have any FSMO roles so I wont
need to worry about that.

I was thinking of doing the following...

1)put the new machine on the network and add it do the
domain (it has a different name than the old dc)
2)Demote the existing DC. I hoping that this will clear
all info from AD for the entire site
3)Promote the new pc and the new dc

We are using static address so DHCP isnt a problem

Regarding DNS, I was thinking of pointing all client
machines to a different DNS server (different location)

Then install DNS on the new machine and let everything
register over a few mins (I think)!!!

Can and should I back up the old DNS server. I will be
creating a integrated DNS server.

Please advise,

Thanks again,
 
Inline.

/Jimmy

It should take care of everything as long as you wait for the replication to
take place.
3)Promote the new pc and the new dc

If you demote the old one first all domain data will be lost if you don't
have another DC online.

Ok, that works.

It should.

If it's AD integrated today it will be part of the system state backup.
