AdPrep on existing domain

Hi,

I'm trying to add an additional domain controller since one at our sites failed recently.
I installed Windows Server 2003 R2 on it but didn't run the second CD.

I am not creating a domain, just want to add another domain controller : In this situation, is running adprep required or not ?

Thanks.

Yes it it
In order to add an R2 DC to an existing nonr R2 domain you need to run
Adprep /forestprep
Adprep /domainprep
from
\CMPNENTS\R2\ folder on CD2
Yes it IS
In order to add an R2 DC to an existing none R2 domain you need to run
Adprep /forestprep
Adprep /domainprep
from
\CMPNENTS\R2\ folder on CD2
Hi
If your forest/domain is not prepared it must be prepared before joining an W2K3 R2 server. First you need to prepare the forest (adprep /forest) then the domain (adprep /domain) using the R2 tools (from CD2)

Hi KCTS, Dan,
Sorry if I sound cluelessness but shall I run this to my non-R2 Primary domain controller (which is not R2) or just on the new server I am trying to promote ?

Thanks,

PS: KTCS, you sure are helping me a lot these days... thanks a lot.
Thi need to be run on the EXISTING DC.
If I could type I'd be dangerous!

This needs to be run on the EXISTING DC. - Ie put the R2, CD2 in the Win2000 machine and then run
Adprep /forestprep
Adprep /domainprep
from the
\CMPNENTS\R2\ folder on CD2

Ok, thanks a lot for the clarification.
I guess it is supposed to be an harmless process and that no particular precautions have to be made ?
Actually, I am not sure if it has been ran already : is there a way I could find out ?

I think they were my last questions on that subject.
Thanks again.

Thanks a lot.
I asked this question relating to this problem described here : https://www.experts-exchange.com/questions/23210083/Can't-add-a-new-server-as-an-additionnal-domain-controller.html

I have a AD training booked in the next months as I'm not experienced at all with it, but in the meantime, I have to do what I can to solve the current issues.
Would you mind to take a look please ? I believe it should be an easy problem for you.
I have asked this adprep question just to rule things out but I rather think it is a DNS issue...
Thanks !
