Great
info Diane! I knew it should work in theory but did not know of any
real-life
practice. I guess the biggest drawback is having duplicate
hardware?

We did the same thing (lab cloned from production) which was initially
isolated but we slowly cracked open the blocks we had on our lab from our
production WAN with no "ill effects". Our key was that our lab setup has
an isolated "namespace" from our production world. Separate WINS, DNS,
etc. and the one setup knows nothing of the other setup and vice versa.
A device that can talk to one setup will not be authenticated or validated by
the other. We've had this up for about a year now with no
problemos. Again the key is to kept you name
spaces isolated.

This will work as long as you are on two separate physical
networks. In other words you machines from the two domains cannot and
will not be able to communicate - separate hubs, switches, router etc......
The two domains can never exist on the same physical wire plant or like
David says you will create a living nightmare.
This is how I tested our upgrade to AD.
NT4 BDC brought online synchronized the domain took the
BDC offline and moved it to an isolated
lab.
Promoted it to a PDC - all user accounts etc were
intact
Upgraded it to W2K and AD
We
then had a fully functional test domain that mimicked the production
domain. We then added E2K servers, print servers etc until we became
comfortable with W2K and formulated and documented a plan for production
migration.
The point I am drilling in is isolated lab area for testing, do not
do this on the same physical plant!

Nope, the domain sids will be the
same, just the descriptive names will change and you'll have all
manor of problems.

Subject: [ActiveDir] NT
upgrade
Hello
everyone,
I would like to test a
domain that has been upgraded from NT to 2000. If I upgrade an NT
domain (domain1) to a 2000 domain and name it domain2, will the NT
domain remain functional? In the end I would like to upgrade an NT
domain to a 2000 domain and have both online and functional.
I plan to do this by taking an NT BDC offline, promote it to
a PDC, upgrade it to 2000, then name it domain2, and bring it back
online. Will this work? Can anyone see any potential
problems?
Thanks,
Brian
