    I am process of adding a windows 2008 domain controller to a environment
    currently consisting of two windows 2003 sp2 domain controllers. One which
    has Exchange 2003 installed. I want to add the new domain controller to the
    environment and reitire on e of the domain controllers(the one without
    exchange). Is keeping keeping the windows 2003 DC with Exchange 2003 going
    to work with the new windows 2008 DC?

  2. Hello 2010,

    You need to install Exchange SP2 if not done, otherwise Windows server 2008
    will not work with exchange. Also keep in mind that you can't install Exchange
    2003 on windows server 2008.

    Additional Exchange on DCs is not recommended:

    After adding the new DC make it also the FSMO roles holder, a new security
    group will be creaeted when you move the PDCEmulator role to the 2008 DC
    for example.

    Before starting check with dcdiag /v, netdiag /v and repadmin /showrepl for
    errors on the existing DCs.

    Best regards
