Well, maybe not!! :-)
Miracles of miracles, the DNS has the right name this morning when I came
in. Something changed last night after midnight (when I went to bed).
It wasn't my box as I left it on. I've sent email to the DNS engineer
to see what changed. So far, no answer ...

I hear you. Some folks here think that Linux is something cool
and so new and fresh... I've been mucking around with Unix since '85
and i think FreeBSD (or the *BSD derivatives) are the best thing going.

Cool. Didn't even know it was there.

Old box works, too. I do believe the DNS server was "broke". It uses Solaris,
and it figures! :-))

You did help - look at all the experience I gained!!
Now all I have to do is get the stupid Integrated sound card (Intel
ICH-based (AC97?)) card to be recognized and set up X (integrated
Intel 810 video card) on this Dell GX110* and I'm all set!
Thanks again,
Shawn
* - Don't laugh!! It's all I have. I moved up from a P333 HP Kayak
with only 32Meg/ram and a 2G HD to this "monster" - P866 with
128Meg/ram and a 20G HD. I'll take it!
