Adding a first 2008 R2 64 bit DC into 2003 R2 Domain

Hello,

A very similar question has been recently posted, but my situation is a bit
different.

I have only one domain with two 2003 R2 DC (replication). We want to get
better hardware and centralize all (Virtualisation + Remote Desktop). All
virtual Servers are 2008 R2 64 bit and one of them will be promoted as DC
that I want to include in the current domain.

I suppose that the replication will then automatically happen, from the 2003
R2 DC.

The current system should not be disturbed with this add. A new version of a
strategic application will be installed and tested on the 2008 Server.

When all is working fine, my intention is to depromote the 2003 R2 DC,
making the 2008 R2 DC as main DC

Are my thoughts ok and will it be so simple as I imagine?

Thanks for some advices.
Hubert

Hello Hubert,

See here about adding new OS DC to an existing domain:
http://msmvps.com/blogs/mweber/archi...r-2008-r2.aspx

"A new version of a strategic application will be installed and tested on
the 2008 Server", i just will mention here, that you shouldn't install applications
on a domain controller, a DC should only be used for AD/DNS/GC and maybe
DHCP, if no member server can do DHCP, that's it.

Also you have to keep in mind that for DCs as Virtual machine the same backup
and recovery options apply as for physical machines, so NO images or snapshots.
They will result in USN rollbacks and are not supported ways from Microsoft,
still applies for Windows server 2008 and higher:

Good advice! I could have forgot this...

Thanks a lot for your complete answer (as usual) and the other links that I
will certainly read

Hello Meinolf,

Concerning your links, I have still some questions:

I must run adprep.exe on the 2003 R2 machine (Current Version 31). This is a
production Server... Could it cause some problems?

I had a short look to the other links and I must admit that I have been a
bit discouraged from all these points to take care... A third party company
is doing the virtualization and installation of 2008. I hope they know about
this...

2003R2 ist on a physical machine but I think it is not possible to keep it
as main DC against the new 2008 instances, isn't it?

Best regards
Hubert

The above errors belong to the system log event viewer, so check at time/date
for errors and if they are already solved.

Normally not, either it runs or you will get an error message. As replication
to other DCs occur about the changes, maybe you should do it on COB, depends
on your environment and how busy the machines are.

If they are good, they know about.:-)

Of course you can keep a physical machine as DC and sometimes with not so
powerful machines it can be helpful to have a physical machine that has the
FSMO roles and is DNS/GC also. But with Windows server 2003 R2 as DC you
cannot have the advantage of the functional level features coming with Windows
server 2008 R2, as they require pure Windows server 2008 R2 DCs.

Meinolf, some other thoughts about DC on Virtual Machines:

The images or snapshots problems occur in replication situations, isn't it?

My customer is a small company with some subsidiaries. As we want now to
have all centralized in one place, thus it would be ok to have only one DC
(in fact no need to have more). In that case, restoring from an image would
be no problem? We have organized, I think, a good hardware. All is double
and failsafe.

Hello Hubert,

WIth a single DC using snapshots will not result in USN rollback. But with
using virtualization solutions you normally have a SAN and so better count
some space for the AD aware backup solution, which also allows you to restore
single objects.

Hello Meinolf

I was today by my customer and had some discussions with the third party
company.

I have seen that the actual DC is in "windows 2000 mixed mode". I can
remember that I have done this 4 years ago, because I was not sure whether
old PCs would be used or not. Now there are only XP clients. To be more
accurate, there are actually 2 DC in same domain with replication: one ist
Server 2003 Standard SP1 and the other is Server 2003 R2 Standard SP2. Both
will be removed after successfull installation of 2008.

Thus, I suppose that the next thing to do is to raise the domain function to
"Windows 2003 Server", on both DCs (?)

After this, if I have understood correctly, I would rund adprep.exe (64bit,
from the 2008 R2 CD) on the 2003 DC machine to upgrade the AD schema version
(the other 2003 DC will be automatically upgraded?). Then promote the new
2008 R2 Server (one instance) to DC and the replication will occur. Finally
I should have all AD data on the 2008 instance. I can remember that I have
already done something like this (for replication) about 2 years ago, and
with your help if I am right.

The other company seems to prefer the other way around: I should only raise
the current DC to "Windows 2003 Server". They would somehow make the 2008
instance compatible to 2003 and the replication would occur. After the
application is installed and working, we would remove the 2003 Servers and
the new server would run then in full AD 2008 mode. I am not sure I have
understood all but he says they have done already that way on other places.
He seemed not to understand why the schema on 2003 should be upgraded.

From my point of view, if his solution works, I am happy when I do as less
as possible on the production server. And if it not work, it would be more
his problem as mine and then we could continue with your suggestion.

Perhaps you could give your feelings about this?

Thanks and best regards
Hubert
