Doesn't seem weird, sounds like rmi and attbi have old authorative data in their local DNS. Pretty easy to test. DIG or nslookup against the rmi / attbi name servers and see if they return a different authorative answer. If their server returns an old address you simply need to get them to remove the zone info from their DNS. -- andy On Thu, 3 Oct 2002, Mitchell S. Baltuch wrote:

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
