Ok, so if it is two domains (each with their own
DNS server set) there are two basic ways to get
resolution:

    1) Put them in a hierarchy
    2) Have each DNS server (set) hold "cross
            secondaries" for the other DNS zone(s)

#1 works best when you have only one tree of
zones/domains OR (in a lab etc) don't need
Internet connectivity.

#2 is a general solution -- if each set of DNS
servers can resolve the other DNS zones directly
by being a secondary for those other zones then
it just works.
