wierd problem

["Mitchell S. Baltuch" <mbaltuch () mountainstorm com>]

I have a client who is having a problem with DNS.  Most everyone can 
reach their web sites and send email, except those on attbi.com and 
rmi.net.  For those people, dns lookups fail approximately 50% of the 
time.  The domain used to be owned by someone who use rmi.net to host 
the domain.  As far as I can tell, the gTLD servers return a correct 
response, and every other ISP appears to resolve the domain correctly. 
I have had no luck talking to ATT and RMI (earthlink) support (no 
surprise there).  Any ideas how to diagnose this further.

Thanks,
Mitch
