Hi group

I have a Windows 2003 DC/FSMO server with Exchange 2003 on the same server.
I want to move the FSMO services onto a new Windows 2003 R2 Domain
Controller in the same domain. Will this cause any problems for Exchange?

Thanks for any help.

Al

Where's the GC going to end up, or are they both going to be GCs?

Hi

Well, the new server is actually going to replace the old one; the old one
was set up originally without any kind of fault tolerance so I've set up a
new ML370 with RAID controller and RAID1 (OS) and RAID5 (storage). I've
already made it a domain controller and made it a Global Catalogue server.
Now I want to move the FSMO services and install Exchange 2003, move the
mailboxes over and switch off the old server.

The old server will be rebuilt with fault tolerance and become a replacement
for my existing file & print server (not fault tolerant).

So, the original question is - will moving the FSMO services to the new
domain controller have any effect on Exchange 2003, which is used daily and
currently installed on the current FSMO server? I need to keep Exchange
running while I install the new domain controller.

Thanks

Al

You can move the FSMO roles, but you cannot run dcpromo on the Exchange
server as long as it is an Exchange server.  If you installed Exchange on it
while it was a domain controller, it must remain a domain controller.

Hi

Thanks for the reply.

When you say 'If you installed Exchange on it while it was a domain
controller, it must remain a domain controller', what do you mean? Do
you mean I can never run dcpromo or switch it off because it will
corrupt my domain or do you mean I could switch it off forever with no
problems?

Thanks agin.

Al

You have read way, way more into it than was intended.
If Exchange (any version) is installed on a DC you cannot demote the
DC to be a member server. You can reboot it all you like.
If Exchange (any version) is installed on a member server you cannot
promote the member server to be a DC. You can reboot it all you like.
