    SBS 2008 migration - DNS issues?

    I have started a migration from sbs 2003 to sbs 2008 premium. I have done
    the basic load (everything up to starting the migration wizards on the new
    server) so far and had one installation issue. The issue was that I could
    not download updates.

    When I try to run the CTIW it errors. Says that it cannot connect to the
    internet. It cannot grab my router and make any changes (old router, not
    upnp). However, my router is working fine with the 2003 server.

    So, basically, no one on my network can connect to the internet and/or the
    old exchange server. The new server cannot connect to the internet.
    However, it does receive name resolution but will not ping.



    I have turned off the firewall on the new server, just in case. I have not
    installed anything whatsoever on the new server.

    As far as I can tell, the new server is now acting as a DNS server as well
    as the old one. If I change the DNS on my clients, they are able to connect
    to the internet and the old server. If I change the DNS on the new server to
    point to the old server, it still does not work and I believe that the SBS
    2008 needs to point to itself anyway.

    Regardless, it seems as though I have some type of a DNS issue on the new
    SBS 2008 server and it has stalled my migration.

    I thought that maybe I needed to do the CTIW from the migration wizard, but
    that made no difference.

    I have the ports on the router/firewall open, somewhat, they are redirected
    to the old server.

    I do not know if I have provided enough information.

    Any assistance would be greatly appreciated.

    SBS 2003 had one nic, no ISA.

    The sbs 2008 server has 4 NICs, three are disabled.

    sbs2008 ip info:

    ipv4 - 10.0.1.10 (Preferred)
    S/N 255.255.255.0
    GW 10.0.1.1
    DNS 10.0.1.10 and 10.0.1.2
    Netbios over TCPIP

    10.0.1.10 is new server
    10.0.1.1 is watchguard firewall
    10.0.1.2 is existing sbs2003 svr

    there is IPv6 info, as well, but didnt include it.

    None of your servers should point at the firewall for DNS.

    The SBS box should point at itself for DNS.

    If you want to resolve DNS between two different SBS domains, in the
    network, setup a DNS forward to the OLD one from the new one, but the
    new one should point at itself.

    Never point at a external DNS on the NIC.

    Actually, until the new SBS 2008 server has been joined to the domain and
    the actual migration begins, it should point DNS to the old SBS server, not
    itself. Once it is joined to the domain and AD enabled, then it should only
    point to itself. (And you are absolutely correct - it should NEVER point to
    an outside DNS, or to the router/firewall as a DNS server.)

    Also, ensure that IPv6 is enabled on the SBS 2008 server or things will not
    work correctly.

    Re: SBS 2008 migration - DNS issues?

    Problem is resolved. I updated the firmware for the NICs and restarted.
    Everything worked fine. Reran CTIW, everything passed.

    Not sure if it was the reboot that fixed the issue or if it was the new
    firmware.

    Thanks to everyone for their responses, quick I might add, they are welcomed
    and appreciated.
