Hi guys.

I have recently transferred several virtual domains to another web hosting
service, but my nameserver does not see the domains on look up (none of the
ones I've transferred to this one hosting service).  The interesting thing
is that I have transferred other domains to other hosts and havent had this
problem so I'm having difficullty accepting that its my problem, but hey it
could be I guess.  I will outline what I see below:

ok heres a for instance:

I do a whois chesserrealty.com from my nameserver and I get
   Record last updated on 21-Jul-98.
   Record created on 17-Oct-96.
   Database last updated on 20-Aug-98 04:21:41 EDT.

   Domain servers in listed order:

   NS1.GRNCO.NET                208.21.151.1
   NS2.GRNCO.NET                208.21.151.2

ok, so then I do a nslookup for www.chesserrealty.com from my name server I
get
No match for "WWW.CHESSERREALTY.COM".

of course I cant ping em or traceroute them since I cant look them up :)

Now the interesting part:

I use nslookup off of another server... like this:
ns# nslookup www.chesserrealty.com ns2.mci.net
Server:  ns2.mci.net
Address:  204.70.57.242

Non-authoritative answer:
Name:    www.chesserrealty.com
Address:  208.21.151.2

so now this is weird.  these domains have been transferred for quite a long
long time.
I got to looking in my log files and I see lots of entries like this:

Aug 15 14:26:56 ns named[11593]: "151.21.208.in-addr.arpa IN NS" points to a
CNAME (ns1.grnco.net)

Just out of curiosity, I ping ns1.grnco.net and I get
ns# ping ns1.grnco.net
PING hal.grnco.net (208.21.151.1): 56 data bytes
64 bytes from 208.21.151.1: icmp_seq=0 ttl=52 time=124.032 ms
64 bytes from 208.21.151.1: icmp_seq=1 ttl=52 time=123.728 ms
64 bytes from 208.21.151.1: icmp_seq=2 ttl=52 time=123.395 ms

so this is what I _think_ is happening:
the name server @ grnco is really named hal.grnco.net, from the lookup and
pinging.
ns1 is a cname for hal...
the reverse records in their in-addr.arpa mapping is pointing the NS entries
to a CNAME
which is a no-no from what I've seen / read.

Would my name server be refusing their "broadcasts" due to this?

what else can I try or look at?
