We have two windows 2003 server one primary and other additional domain.
Primary with DNS and additional with secondary DNS, and I have 4 child domain after this tow,
The primary has big problem but still on line I want to promote the additional domain as Primary domain.
Reformat the old primary and make additional for promoted one
What is the best practice recommended by Microsoft in this scenario needs , and also that there will be no problem in all forest main and child domain and also for the group policy
