Win2k8 install killed dns domain

Hi,

I had one tio.nl zone internaly with two sub domains for staff and student.
The student part was not aWindows domain yet, the staff domain and tio.nl
domain were already windows domains.

Today I created the student.tio.nl Windows domain using dcpromo on a Windows
2008 server. To my amazement the installation killed my student.tio.nl
domain in the original tio.nl zone and created a link to a new
student.tio.nl zone hosted on the new Windows 2008 server.

Was this because I finally agreed the have the new server also becoming a
dns server?
I wanted this as I am going to transfer all dns servers to the new domein
later this year.
I don't even realy mind it being a new zone as it will be hosted on the same
dns servers but... I have lost all information in the old student.tio.nl
domain. :-( The new zone on the new dns server did NOT transfer the
information so for instance all MX records etc are gone.

As I am fully aware of what zones, domains, etc are both in dns and in
Windows I was highly surprised when this happened. I have read every screen
carefully before agreeing to the setup.
I am a both a Win2k and 2k3 MCSE and studying for 2k8.
Of course in my study/testing I did not have a 2/3 operational network with
Windows 2003 servers where I needed to add one new domain with a Win2k8
server. :-(

1) Can I simply undo what was done and get the old dns zone information
about the student.tio.nl domain in the original zone back?
All zones are AD integrated. The are no files in the
C:\WINDOWS\system32\dns\backup directory
2) Which option did I select that made the Win2k8 dcpromo command kill the
original zone?

1. You would have to perform a restore on one of your domain controllers
(of the DNS tree, depending on which replication scope you had set).

No other record of it exists (allowing you to avoid the restore)?

Setup creating the delegation would have done a good job of trashing it
in the meantime.

2. Hmm I forget if it even asks you. I was moderately sure there was an
advanced / "leave DNS alone, I'll do it myself" option.

If you have the DCPromo do it all for you it does tend to run roughshod
over everything you might have put in place yourself.
