I would like to add 2003 standard server as another domain controller(like BDC) to my existing 2000 domain.

what would be the steps to achieving this. The 2000 server has no exchange server so that is not a concern.
i m looking for specific answers. thank you
Alex

Hi icdl101,

with windows 2003 R2 (release 2) you will need to run the adprep tools from the second cd supplied in the 2 cd set!

\CMPNENTS\R2\ADPREP

you can also download here
http://www.microsoft.com/downloads/details.aspx?familyid=5B73CF03-84DD-480F-98F9-526EC09E9BA8&displaylang=en

this boosts the schema up to cope with R2 functionality
http://www.microsoft.com/windowsserver2003/r2/whatsnewinr2.mspx

If you arent adding a 2003 R2 server, then you just run the adprep /forestprep and adprep /domainprep tools on your 2000 DC from the I386 folder of the 2003 cd

after that you basically run DCPROMO on your new 2003 Box and add as an additional domain controller

make sure your DNS zones are AD inegrated and everything will be well

easy huh :)

no no you have to run adprep /forestprep   adprep /domainprep and adprep /gpprep  all from the second cd in the R2 set  you do this on your 2000 machine

the idea is that it extends the 2000 schema to cope with 2003 changes

i have installed active directory, all the user accounts and computer accounts have replicated seemlessly.
Right now it is showing me 2 domain controllers(Server1 and Server2)
i havent run DCPROMO yet. When i had intiated active directory , i added  the 2003 server as another domain controller in an existing domain.

So my question is do i have to still do DCPROMO?

your confusing me

you cannot "install" active directory without running DCPROMO     a server cannot be a domain controller without DCPROMO being run - hence the name  Domain Controller Promotion (DCPROM)

so what have you done exactly?

1)  I did the adprep /forestprep, adprep /domainprep, and adprep /domainprep /gpprep on the 2000Server. (oh by the way  at that time the 2003Server was not connected on the network, though previously i had added it to the domain, without any server manager configutration) i m trying to give exact steps and conditions.

2) Now once finished with 2000server i configured DNS on 2003server. Then server manager i used the wizard to i chose the option of  another Domain controller(active directory), then i chose the option of another domain controller in existing domain. it created the the active directory and at the end gave me a message that i had created Domain Controller.

3) when i checked the active Directory in 2003 Server it showed all the user accounts, computers and even the group policies from the 2000 Server.
I checked the 2000 server and under the active Directory domain i found 2 domain controllers Server1(2000) Server2(2003)

4) Just to check now i ran DCPROMO from the Run command and it told me that Server2(2003) is already a Domain Controller. The only option was to Demote it, so i cancelled that option and left it alone.

So please tell me where i have royally messed up. (this is the first time i m doing this).

I created new user account on Server1(2000Server) after all this just to check if things were working., almost immediatley the user was replicated on the Server2(20003Server). so i m assuming things are working ok.

i will be moving over the shared documents and applications on monday to see how things are going to go. I have left the Server2(2003Server) running for the weekend.

you have done it correctly and well :) you now have two domain controllers that seem to be working fine....

if you are worried, try running dcdiag on your 2003 server

For future reference to anyone reading this, after this i had to tranfer fsmo role, enable global catalog on the 2003 server.
The fsmo would not transfer all the roles so i had to run NTDSUTIL to seize the role. Everything ok from there.
