AD R2? How to tell [message #161197] Fri, 18 September 2009 10:23 Go to next message

Hi guys, I have a question regarding introducing a 64bit Win2k3 R2 DC into
our 32bit environment.

I have read that to successfully introduce a 64bit 2003 DC, the schema in AD
needed to be updated with the R2 version.

I didn't move our current environment from 2000 to 2003, we are running 2003
native that I have verified forest and domain. The SA that did do the upgrade
said he used the R2 version cd, but the logon screen to our Windows 2003 DC's
none of them say Windows 2003 R2. I have seen that to get the ctrl-alt-del
screen to show Windows 2003 "R2" you need to run the second CD. But do you
really need to? How can I tell if our AD forest will support a 64bit DC? I
don't want to get half way through trying to promote a 64bit DC only to error
out or worse yet corrupt our AD infrastructure.

Any insight would be appreciated!

Thanks,
Mike

Active Directory doesn't care about what architecture the DCs run on --
the data in the directory is the same. There are no special preparation
that you need to do prior to introducing a x64 DCs to the domain.

Further, it is possible that, although your DCs run on Windows Server
2003 (without R2), the schema could be prepared with the 2003 R2-CD.
It's just a preparation, you don't necessarily need to introduce a DC of
that version, right-away.

Cheers,
Florian

Hello Mike,

For AD it doesn't matter if you run 32 or 64 bit architecture. You have to
upgrade the schema when you like to add a 2003 R2 DC from the second 2003
R2 disk set, that is correct.

If that machine should only be a member server, there is no need to upgrade
the schema.

2003 uses version 30 and 2003 R2 version 31. You can check with "schupgr"
in a command prompt on the DC.

Best regards

Meinolf Weber

there is no dependency between OS architecture (x86 or x64) and AD version
or AD schema version

the person that told you you need R2 AD to be able to introduce x64 DCs,
does not really know what he's talking about

there may be a dependency between OS version and AD version
