adprep /forestprep and /domainprep on w2k3

By ericwch ·
Hi all,

Recently , I've purchased a new server that comes with w2k3 r2 32-bit OS. When I run the program DCPROMO on it to join my w2k3 domain, it prompt me that 'active directory on the source schema operation manager is not compatible with my server'

After , going searching through and looking into MS website, they recommended me to upgrade the source w2k3 schema master with disk 2 of the w2k3 R2 media.

I am concerned with this action because I have an Exchange 2003 sitting on my current server too.

My question is how much impact will I get after I have done the upgrade, especially the Exchange 2003 server. Btw, I have only one mail server running in my compnay.

Windows 2003 R2 is really Windows 2003 SP2

by Why Me Worry? In reply to adprep /forestprep and /d ...

And because R2 introduces newer version of dll files and kernel into Windows 2003, any non R2 servers will obviously have a different version and build of the core dll and kernel files that make Windows 2003 what it is. I agree with the the article that you will need to apply the R2 updates onto your schema master, but you should not worry because the server will still be a Windows 2003 SP1 server, not a full R2 build. The second disk of R2 will install updated core kernel and AD schema files to allow you to run domainprep and forestprep. You should by all means take a backup of your AD tree before you do this just to be safe, but I don''t see any issues in applying the R2 code to your schema master. Also, you don't really have much of a choice because you can't get around it any other way.

r2 is not sp2

by itadmin In reply to Windows 2003 R2 is really ...

If your cds are labeled w2k3 r2, then you have w2k3 r2 sp1. However, if, and only if, your cds are labeled w2k3 r2 sp2, then, and only then, do you have w2k3 r2 sp2. And both of these versions are not to be confused with ms's earlier offering of w2k3. And, of course, each version has its own (ms recommended) upgrade path etc.
