I am having a problem getting email from a particular site and I believe it
is because of a DNS problem. The domain is wsd-moscow.ru and if I perform an
nslookup on that domain with my current DNS configuration the lookup
times-out while I am able to lookup, for instance, goggle.ru, microsoft.com,
etc. I know it is a valid domain. I thought the root.hint servers were
supposed to take care of particular DNS routing such situations as this. My
DNS server is 2003.

Any would be very appreciated!!
Thanks,
Bob

Yes, it is a valid domain, but I've test resolved this domain against seven
different unrelated DNS servers with a type=any query and the best time I
could get was 745 ms, most were over 1500 ms and up to 2406 ms.

If you are behind a Cisco PIX or another firewall that blocks DNS
extensions that uses UDP packets over 512 bytes, it could be an EDNS0 issue.
