Promotion a new Domain Controller on Win Server 2008 to existing Domain with working Exchange 2007.

Please Help !!!

Situation:

Domain Controllers:
1. DC1 on Windows Server 2000 (without roles)
2. DC2 on Windows Server 2003 (with all roles)

Microsoft Exchange 2007 on Windows Server 2003 (not Domain Controller).

I install Windows server 2008 on a new server. And planning promote this server to Domain Controller and demote Domain Controller on Windows Server 2000 (DC1).

Questions:
1. How this promotion can cause problem on Exchange 2007 ( I mean forest and domain preparations ) ?
2. Should I first demote DC2 and then promote new server to Domain controller and not the reverse?

Thanks

Hi,

You said DC2 is on Windows 2003 and only one DC with Windows 2003 in forest so don’t demote it first since Exchange 2007 requires Schema master on Win2003 SP1 or later so suggest you to install Windows 2008 first move all the roles and then demote DC2. This process doesn’t affect your Exchange 2007 environment.

Do you still need DC1 which is on Windows 2000? I would say demote DC1 and keep DC2 since it is on Windows 2003 and which the minimum requirement for Exchange 2007 also.

Just curious if you tried this yet? I'm in a similar situation getting ready to put my first 2008 server in and promote it to a DC. I'm already running Exchange 2007 SP1.

I'm curious how it work and if you had any problems.
