[tlug] DNS servers down?

["Jean-Christian Imbeault" <jean_christian@example.com>]

General question concerning DNS servers. I have two networks at work (ISDN 
and ADSL) and I can "see" an outside machine by "name" (not ip) on one 
network (ISDN) but not on the other (ADSL). I get an error message like 
this:

[root@example.com]# telnet www.av-navi.co.jp 80
telnet: www.av-navi.co.jp: Temporary failure in name resolution
www.av-navi.co.jp: Host name lookup failure

However a telnet to other world machines (like hotmail) works fine.

Does this mean that some nameserver (possibly my ADSL provider's) is 
misbehaving?

What can I do to diagnose this problem further so that I can find the root 
problem and how to fix it?
