    I'm looking at adding a server 2008 DNS server to our Current AD
    infrastructure we've performed ad prep to get our domain ready for server
    2008 and we've added a server 2008 DC to our domain. Now we'd like to add a
    third DNS server (by adding it to our server 2008 DC), but I can't find any
    documentation regarding interoperability between server 2008 dc/dns and
    server 2003 dc/dns.

    If I add DNS to our server 2008 DC will it operate without issue with our
    server 2003 DC/DNS servers?

  2. Sure, no problem. Just install DNS on the new 2008 DC, and wait about 15 to
    30 minutes, and the zone auto-appears.YOu can then make the DNS entry on
    each DC (assuming you haven't already done so) to be itself as the first
    entry, and a partner DC as the second entry. In this case, I would make the
    2008 DC as the second entry on the 2003 servers. ON the 2008, make itself
    first, then choose one of the others (in the same Site) as the second.

    FYI, some basic facts about 2008/2003 mixed environment, you will want to
    transfer (not seize) the FSMO roles from the 2003 to the 2008 server. Make
    sure you make it a Global Catalog as well. I assume this is a one domain
    forest, so all DCs should be GCs in such a scenario.

  3. Hello trnsfrmrsr,

    If you use use AD integrated zones, which is my preferred option, on the
    DC's, just install DNS server role on the new server and wait until the replciation
    is done. AD will replicate also DNS zone information complete, no additional
    DNS configuration is needed.

    As Ace allready mentioned move the 5 FSMO always to the newest OS DC, in
    2008 this will create an additional group in AD, the "Terminal Server License
    Servers group", if the PDCEmulator is moved to 2008.

    Also make all DC's Global catalog server in a single forest domain.

    Best regards
