You are right, underscores are not a valid part of a domain name, even though old DNS servers would allow them (all that is valid is a-z0-9 and a dash, I believe). > Any ideas? Am I going crazy?

I dont know why it is behaving as it does--I would suspect the reason its NOT working is because of the underscore, and 'nslookup' isn't being as pedantic about it as it should be. Two suggestions: 1) get them to fix their domain name 2) use the raw ip addr, as given by nslookup -Brandon Gillespie
