Samba ("Classic", I guess) has been very reliable for us, as well,
going on neigh... 20 years? More? Switched to it when Sun's PC-NFS
turned out to be an utter cluster frack.
It's the integration between Samba, BIND and <whatever else> that
concerns me, but if it's been stable for you, well...

Since the Enterprise is 99-44/100% MS-Win on the desktops, there'd
really be little difference between losing the AD DC, the DHCP
server, the nameserver, or the entire kit and caboodle. Not
from a customer POV. As for the network core: Routing is all static,
as are IP address assignments to all mission-critical servers and
network bits (switches, routers).

I've been doing Server & Network Admin. for better than 20 years.
The last time we tried distributing the things upon which the
Enterprise depended across multiple systems we quickly figured out
that all that did was increase the number of points-of-failure that
could cause a partial or complete denial of services to customers.
Since then I've adopted a strategy of "All the eggs in one basket and
make certain it's a damn good basket."

Won't be necessary. See below.

See above. W/o any of the mission-critical services everything falls
over, to a greater or lesser degree, anyway, so it doesn't really

Dual redundant hot-swap PSUs. (One on the UPS, one on the mains.)
The drives are hot-swap, too.

I do, but please understand: Been there. Done that. Got the
t-shirt. I won't claim to know it *all*, but, after lo these many
years, I think I have a pretty good handle one how network
I'd like to thank each of you for your comments--particularly
following my last, rather... *cough* "testy" post to the list. It
was just frustration. Please accept my apologies.
In an email directly to me, Louis offered additional pointers and
input. And offered additional help. Thanks, Louis! And thanks for
the script, too.
So, the good news: I took Louis' script, split it in two, hacked it a
bit, and I *think* I now have an operational AD DC! \o/ The
"root" zone is "example.com" and the AD DC in "addc.example.com".
Tuesday I hope to be let alone long enough by my end-users to try to
get my laptop onto the AD.
Later I will post details on what I had to do to make all this work,
but it's the Labour Day weekend, here in the U.S., I just got back
from an excellent cardio workout, I'm currently enjoying a *very* good
(and well-earned, if I do say so, myself) IPA, and I don't feel like
trying to make sense any more :D
Thanks again, all of you, for your help!
