Hello, listers

I wonder if someone will be able to help me with my DNS problem. We just
migrated to two new domains (after a corporate merger), and I edited all the
occurrences of the domain name on our three RH6.0 machines to reflect the
change. Our corporate services changed the delegation records, and most of
DNS services work as before the migration. The only glitch I found so far is
with CNAME records. Since we have two domains under our control, we use
CNAME records to point to A records in the other domain, so we can use only
host names, doesn't matter in which domain the host is located. Here is an
example:

        in a zone file on the sms primary DNS (sms.domain_name.com):
        tomcat                                          IN      CNAME
tomcat.ndc.domain_name.com.

This set-up worked well until the migration. The CNAME records are still
there, now pointing to the new FQDNs, but when I use just a hostname from
the ndc domain on a host in the other domain (sms) - let's say 'ping
tomcat', I get host unknown error. If I add the sms domain name (the one
which only has a CNAME record) the host name gets resolved correctly. It is
a small problem but since our new domain name is quite long, it is a
nuisance (you know - it used to work, now it does not). Would any of you
have a suggestion as to what may be wrong? TIA.

Regards

Marcin
