Understanding AD/DNS and forwarding to Bind/DNS

    Hopefully someone can help me understand the interaction
    of DNS resolution between 2003 servers and XP clients.
    I understand that in AD it’s probably best to have the clients
    (XP) use the DNS server running in the AD domain. And many things
    seem to work better when it is setup like this. However, I am having
    trouble resolving other names of systems within the same IP domain
    that are not a part of AD and never registered with the 2003 DNS
    server. Ideally, it would be nice if the XP client could, first, try
    resolve the name with the 2003 DNS system then upon failure,
    roll over to the campus DNS (bind) system where some of these other
    systems are defined and receive DHCP numbers.

    Or, if the 2003 DNS system can not resolve the name, forward it
    on to another campus DNS server. For the life of me, I can’t get this
    working.
    Here’s what I’ve got:

    Campus DNS system (bind) that does not allow dynamic DNS updates
    Ip address 10.10.250.100

    2003 server running DNS
    Ip address 10.10.11.65 name max

    XP client
    Ip address 10.10.11.113
    First DNS pointing to 10.10.11.65
    Second DNS pointing to 10.10.250.100

    XP client
    Ip address 10.10.53.113
    First DNS pointing to 10.10.11.65
    Second DNS pointing to 10.10.250.100

    Logins are fast, printers map, shares work, etc
    Problem is that the XP clients can not resolve a system that is defined in the
    10.10.250.100 DNS system but not defined in the 2003 DNS system.
    If I reverse the DNS search order so the campus is first and the 2003 DNS is
    second, new logins on the XP client can not find the AD domain. They can
    however, resolve the “other†IP names in the domain.

    Seems like the 2003 DNS is not forwarding the lookup on to the next
    DNS server because the request is coming from a client that is the same
    IP domain? Helppppppp,

    Thank you
