Is it recommended to keep the internal name different from the public name ?
my company has a registered public name but no web presence. I'm converting
from novell and groupwise and it seems easier to keep the internal name the
same as the public name. Am i out to lunch ? thanks for your help..
 
"recommended"? By some, YES. By others, NO. Personally, I think it's more
beneficial (less headaches) to keep them separate. If you want a longer
diatribe, just ask.

Yes. Though not mandatory.

You need a split horizon DNS if you have the same internal and
external domain names, but it works as well. To my taste, it's easier
to keep internal and external separate, if even just for
organizational issues.

Split Horizon ?
I dont suppose there's any step by step "how to" papers on setting up
separate name spaces ?
What about having internal and external email addresses for each user ? isnt
that more work ?

Better than "Lost Horizon"... :)

Some refer to it as "split-brain".

Sure. A very good one at:

(Google would have found this as well)

Lots more. But why? Split horizon DNS resolves internal and external
clients to different IP addresses for similar domain records. Using
two separate domains does the same, just with different names.
Nothing says you can't use the *same* mail system for internal and
external clients. Your Hotmail account is reacahable from any domain,
correct?

JC> Some refer to it as "split-brain".

"split horizon DNS" is the older term, its possibly earliest use on Usenet
being by Paul Vixie in 1994 (albeit that it had a precursor in the world of IP
routing that dates back to at least 1988). "split brain DNS" alludes to a
surgical procedure that is somewhat drastic and quite ugly, and didn't appear
on Usenet until a few years later.

Jeff,
I like that 'lost horizon' reference! :-)

I agree there is much administratice overhead with a split-horizon
namespace. More uneeded headaches if you ask me. One can search back in the
posts for threads pertaining to users asking, "Why can't I get to my own
website, why can't I get to my website without the 'www' in the URL", among
other things, in a split-horizon scenario. Some of these fixes require
registry entries. Easier to choose a different name in the long run.

Microsoft calls it Split-DNS:
