Hi friends, I already install a new server and with DCPROMO right now it is
a Replica DC of my domain. Now, my question is: Can I just shutdown my
actual DC and the Replica DC will act as the new DC ? or should I do
something before? is something related to "delegate control" ?

thanks men

Re: unplug DC and use Replica DC

If the first DC is providing DNS and DHCP you need to account for that.

Re: unplug DC and use Replica DC

Hi Mr Danny, actually is only providing Active Directory.... so, Can I just
shut it down and begin using the Replica as DC?

What is Delegate Control? is related to this topic?

Re: unplug DC and use Replica DC

Delegate control has nothing to do with this.

If all it's providing is AD then you can turn it off.............but why? If
this is production there is a lot of value in having a second DC on the
domain incase the first one fails.

Re: unplug DC and use Replica DC

Hi Danny, thanks for your soon answer, I need to shut it down to reimage it
(format), and for a while use the Replica as DC, then restart again the
fresh DC.... by the way, with the same procedure (using DCPROMO) can I
return the fresh DC as the Main DC?

In that case, make sure the new server is Global Catalog (GC) by
checking the box Active Directory Sites and Services on the NTDS
settings. Also make sure you transfer the five FSMO roles the first DC has:

http://support.microsoft.com/kb/324801
http://www.petri.co.il/transferring_fsmo_roles.htm

Check whether DNS is Active Directory Integrated and if not, configure
it so. Wait for it to replicate and direct all clients to use the 2nd
DC's ip as the preferred DNS server. Before you *finally* shut down the
first DC, I suggest you plug off DC's network cable for a while to see
whether there arise issues if it is offline.

Unless you *really* have reason to remove the machine from operating, I
suggest you leave it online. To be honest, it seems like you're not very
experienced with AD administration - which actually is not a bad thing -
and I really suggest you consider consulting some external help (a
consultant, trainer, migrator, whatever) to help you get things sorted
(or a least a plan on catching up AD specific administration tasks).

cheers,

Re: unplug DC and use Replica DC

Hello Hernan,

If the new DC is also DNS server and DHCP, if you are not using fixed ip's.
Additional make the new DC Global catalog server BEFORE shutdown the first
one. Also the clients has to know the new DNS server, otherwise they can
not logon, because they have to contact a DNS server to find the domain controller.

Re: unplug DC and use Replica DC

Hello Hernan,

Delegate control configurations are stored in AD so if the replication is
done completely before shutdown the old one, no problem and effect.

Re: unplug DC and use Replica DC

Hello Hernan,

Please do not image a DC, additional you wrote format, what is the correct
way. Imaging and reinstalling a DC results very often in problems, because
the Update sequence numbers from AD are creating conflicts.

If you remove the DC this way without demoting, what will be the correct
way, the entry is still existing in Active directory and has to be removed
from the database by hand with ntdsutil according to this: http://support.microsoft.com/kb/216498

As another step you have to seize the 5 FSMO roles to the existing DC according
to this:
http://support.microsoft.com/kb/255504

So try to FIRST move/transfer the FSMO roles before shutting down:
http://support.microsoft.com/kb/324801

Re: unplug DC and use Replica DC

Also, the "replica" needs to be a GC.

Re: unplug DC and use Replica DC

Hi Mr Weber, thanks for all your help, how can I convert my new DC in GC? is
something similar as moving FSMO? do you know a technet link with a
step-by-step?
