Replacing first DC in a 2003 AD domain [message #157776] Tue, 14 July 2009 12:08 Go to next message

Hi

The first server that was promoted to a Domain Controller on our network has
suffered problems. We have a backup domain controller which is working
perfectly. We have a single domain called, for the sake of the argument,
'ourschool.com'.

Can I 'demote' the malfunctioning DC safely? Will the backup DC just step in
to replace it? If I can do all this, what is the procedure to demote a DC?

Thanks, Anastas.

Just use DCPromo to demote it. The process automatcally transfers the FSMO
Roles to the other DC. I would leave it sit and run as a Domain Member for
a few hours afterwards just to be safe. Then remove it from the Domain by
switching it to a Workgroup Name,...then decommission it.

The Globabl Catalog is not automatically adjusted. That has to be done
manually.

Phillip already pointed the correct steps out. Besides demoting the
machine, have you checked what you can do to fix the problems it has?
Are there any symptoms? What problems does/did it suffer from?

Hello Mikoyan,

First i would check with support tools dcdiag /v, netdiag /v and repadmin
/showrepl for errors according to the domain. If no errors are reported,
move the FSMO roles to the other DC and make it also DNS server(use AD integrated
zones) and Global catalog server. If this is done/checked you can demote
it with dcpromo, maybe you have to uncheck the GC on the server when demoting
doesn't work direct and try again.

In a single forest domain like yours you can make all DCs Global catlaog
server.

Best regards

Hi Meinolf,

You suggest I:

Can I use AD integrated zones installing DNS from the 'Manage your Server'
utility

Hello Mikoyan,

No, it is done in the DNS management console. How many DNS server do you
have now, only one or a primary and secondary? If you mark the forward/reverse
lookup zone you can see in the right pane the "type" of the zone you are
running.

Hello Mikoyan,

So i assume the DC which should be removed is also the DNS server? Then open
the properties of your dns zone and on the General tab you can switch under
the "type" to AD integrated zones.

Now i that is done install the DNS server role on the DC that you keep. Do
NOT configure anything after installing DNS, skip the pagges popping up.
Give it time and wait for replication from the existing DC/DNS until all
zones appear. Now compare the DNS server properties from old and new DNS
server. Reconfigure the clients to use the new DNS as preferred on the NIC.

Best regards
