Exchange & DNS Question

[Moido]

I have 2 domains in our network as follows:

domain 1 = adomain.com
mail = larry (Exchange 5.5 on W2K server)
DC = curly (Windows 2003 server)

domain 2= bdomain.com , bdomain.local
mail = sleepy (Exchange 2000 on W2K server)
DC = grumpy (W2K server)

Users from bdomain.com can send emails to adomain.com but emails from
adomain.com does not get to bdomain.com. We receive "host unknown" error
message. Each domain receives all other emails without any problem. I am able
to do forward and reverse DNS lookups of the other domain from each domain.
Any help would be greatly appreciated.

Hi,
check the DNS entries for the bdomain on the exchange for the adomain with
nslookup (in cmd).

Is there an zone-entry for the bdomain in the A-DNS-Servers?

cheers,
Andy
