Remove Zentyal-DC from Active Directory Win**** based ?

[Yuko]

Dear All...

I want and will build Zentyal server as BDC in my Wind**** environment Active Directory.
I have read the article about how to add Zentyal as BDC in Wind****.

But I did not find the article how to demote and remove Zentyal BDC from Domain-Controller ??
Any article about that ?? Please let's me know..
Just in case, maybe we need to do it for next day.
Thanks for your suggest.

Regards,
Yuko
