help - no DNS entry

[Mary Bush]

Can anybody tell me what it means when there are repeat "no DNS" entries -
not just a couple of busy, unavailable URL's,  but 15 in a row?  The "no DNS"
responses seem to come immediately, as if Netscape hasn't even gone
looking, and each successive attempt at another URL brings the same
immediate response.  It happens at all times of day.  Could this be a problem
with our server?
A number of people within our building and on our Network, have
experienced this during the last couple of weeks.
I'm running Netscape 3.0, Windows 95.  Our LAN is on a Novell server, and
our web servers are Windows NT.
Thanks in advance.
