How to demote Win 2000 server in my situation?

328 Views
Last Modified: 2013-12-05
This is what I have:

One domain.
Server 01 - Win 2K - DC, DHCP, DNS, GC - File Server, Print Server
Server 02 - Win 2003 Std. - DC, GC - Exchange 2003 on it.
Server 03 - Win 2003 Std. - member - ERP, SQL 2000 on it.
Server 04 - Win 2003 Std. - Master with 5 FSMOs, DC, GC, DNS - Engineering software on it, File Server, Print Server
Server 05 - Win 2003 Std. - member - Blackberry Enterprise Server on it.
Server 06 - Win 2008 Std. - member - Terminal Server
Server 07 - Win 2K - member - TS 2000 to log in internally


Goal:

Add

Next week
Server 8 - Win 2008 Std. - NAS server with MS System Center Data Protection Manager 2007
Next week
Server 9 - Win 2008 Std. - Exchange 2007 on it - migrate Exchange 2003 to it - shut down Server 2
October 2008
Server 10 - Win 2008 Std. - ERP Software with SQL Server 2005 on it - shut down Server 3
Spring 2009
Server 11 - Win 2008 Std. - DC, GC

First step:
Demote Server 01 - 2K (DHCP has to be moved to Server 04)


What whould be the quickest and rather the least 'dangereous' way of demoting the Win 2000 Server.

As long as the Windows 2008 server is already a Domain Controller and has DNS running on it, you shoul dhave no issues demoting the W2K Server (Make sure all servers and clients are pointing their DNS to the Windows 2008 server before powering down.

Just do a dcpromo.exe on the server. There really isn't much to remove a DC from the network that isn't holding any FSMO roles. Make sure if you are using non AD integrated zones then if the 2k server is the primary DNS to move that role to another server. I woud remove the clean the AD metadata.

Sorry about the last line. I would remove the DC then clean the AD metadata.

Not really any need to clean the metadata if DC was demoted gracefully through dcpromo, though.

Well the dpromo says gracefully but you know how these things are. I do it just to make sure all references are removed because I had a long night trying to figure out what happened one night after a supposed graceful demotion. TiggeMatt is correct that cleaning the metedata isn't required.

Thank you all.

I should mention that I am going to do it this weekend.

I don't have 2008 DC with DNS on it. Actually I don't have any 2008 running as DC.

I am going to make sure that DNS works on Server 04 by shutting down Server 01 completely and log in to a few workstations and browse the network and the net.

Nobody mentioned DHCP. Would DCPROMO take care of it?
And, unfortunately I am still not quite sure how do I check whether the the DNS is AD integrated.

Thank you.
In DNS, if you right click the Zone and click Properties, it will say either 'Primary' or "Ad-Integrated' on the main tab.

For AD-integrated DNS, follow the procedure at http://support.microsoft.com/kb/198437. If your zones show as AD-integrated already in step 3, you are using AD-integrated. I would expect you already are, as this is a default configuration in almost all environments.

DHCP must be manually installed to Server4. You must install it and configure your scopes correctly. Bear in mind that you must not have any overlapping IP scopes between Server1 and Server4 - doing so will cause IP conflicts and could bring the network, or parts of it, down. I would suggest you note all your DHCP config, remove DHCP from Server1, then install and configure on Server4. Remember to transfer all the server and scope options, too.

Also, if you have only 1 Domain controller for your domain, DO NOT demote the existing DC until you have promoted the Windows 2008 server into the Domain.  Otherwise the entire domain will be removed.

jkarnes12 - did you read the author's original post? In that he said Servers 2 and 4 are also DCs, some of which hold the GC role, so he should be fine without the 2008 Server at this stage.

Thank you.

The DNS is AD integrated.
So I guess I should only worry about DHCP this weekend and I should have no problems demoting the 2K server to a member only.

I will definitely be happy or ... asking questions this weekend.
Thank you.

Wes, you're most welcome. Please feel free to come back and post new questions if you have to.

I would still recommend you install DNS to one of your other DCs, as after you demote Server1, you will only have 1 DNS server in the domain. It's up to you, but I would...

Would it hurt if it was on Server 02 - running Exchange?

Although, after I move Exchange 2003 to 2007, which I am going to ask separate questions about, I can have this server running as DC, DNS, GC only.
As well, I am thinking of separating my DHCP onto two separate servers. This would be Server 02 as well until I bring the Server 11 in the beginning of 2009.

Thank you.

No, because Server 2 is also a DC it can run DNS.

If you split DHCP over 2 servers, don't forget to ensure the DHCP scopes don't overlap, and you copy all the scope and server options to each DHCP server.

Since you hace active directory zones you should have DNS on all DCs.

Any word, WesZalewski?

Sorry,

I am not sure whether you expect me to give the answer now.
I am not going to do it until the weekend.

Later I am going to split DHCP onto two servers - Server 04 and Server 02 after the Exchange 2003 is moved.

If it comes to points I feel it will be fair to split them between tigermatt and dariusq.
I'm sorry if someone feels it is unfair. The two experts gave me the most understandable directions and I feel put the most of their time into my problem.

Thank you.
