Active Directory - Operation Failed Adrep

Good day all Experts

I have a small issue trying to bring a second Domain Controller onto my domain.
While setting up the server the below error appears:
--------------------------------------------------------------------------------------------------------------------
The operation failed because:

The Active Directory Installation Wizard cannot continue because the forest
is not prepared for installing Windows Server 2003. Use the Adprep
command-line tool to prepare both the forest and the domain. For more
information about using Adprep, see Active Directory Help.

"The version of the Active Directory schema of the source forest is not
compatible with the version of Active Directory on this computer."
--------------------------------------------------------------------------------------------------------------------
With a bit of research, I found that my current Domain Controller is running Windows 2003 Server where as my new one is running Windows 2003 Server R2.
I went one step further and found out that I require to upgrade my schema on my old server using Adprep.

My first question is as follows, is it not recommended to upgrade my old Windows 2003 Server to Service Pack 2? Is it not easier in the long run? Also installing Service Pack 2, would I still have to run Adprep afterwards?

In the case, if it wound work to upgrade to Service Pack 2 and my only option is to run Adprep, can this be done while the server is in a live environment? Also, would I have to restart the server upon completion?

I have included a screenshot of the error, not sure if it is needed or not.

Furher more, I will definitly be adding more points as I go, because I do have a couple of more questions with regards to the upgrade process.

Kind regards,

You will need to extend your schema to support R2 for those R2 domain controllers

Extending Your Active Directory Schema in Windows Server 2003 R2
Notice you will have to use disc 2 from the 2003 R2 set for that.
Thanks

Hi Experts
Can I then confirm that it does not matter if I had to upgrade my current Windows 2003 Server to Service Pack 2?
I have been reading up and there are people having a lot of problems with the upgrade process. I cant afford to loose my only Domain Controller.

With that said, is it recommended to do this schema upgrade using disk 2 from 2003 R2 while it is in a live environment?

Is there anything else I need to worried about with regards to the upgrade?

I was thinking, I would prefer to have an image backup of my current DC. Is there perhaps a recommended software that I could use to make my image with, before doing the schema upgrade?

Once again, thanks for your assistance.

Kind regards,

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

The upgrade process usually goes well I have never had a issue with a upgrade to R2.

With that said, is it recommended to do this schema upgrade using disk 2 from 2003 R2 while it is in a live environment?
You can do the schema update during business hours you should not have any issues doing it.

Is there anything else I need to worried about with regards to the upgrade?
Just make sure you do a backup so you can restore if you have any issues.

Schema updates updates your schema information with AD which isn't a big process.

Hi dariusq

Just to clarify with you then, for what I need to do, which is bring in another DC into the domain for redundancy. I only require to do the schema upgrade?

I do not require to upgrade my current Windows 2003 Server to R2?

Just so you do know, my current Windows 2003 Server is also my file server, with everyones connecting with Outlook to their .pst files which is on the server. Do you still think it is such a good idea?
My problem is that there are users connecting remotely until late at night. So I really cant have any downtime on this server.

Any recommendations on imaging software?

Kind regards,

Good day gents

I have managed to do the update as recommended by yourselves. I had no issues what so ever.

I thought that this process would have been a lot more complicated and the end it was really a 2 second job.
I have attached a screenshot of the process.
With that said, I do not have any further points to offer to you guys.

Thanks once again for all your help with regards to this problem.

Kind regards,
