I have a domain (school.net) which has a sub-domain, (student.school.net). The school.net domain has 2 DC's both of which are global GC's and one of those have FSMO roles. The student.school.net domain has one DC, which I believe, by default, is the operations master for the sub-domain.
I have had problems off and on with the student.school.net DC (which is the only server in the sub-domain) and want to remove it and the sub-domain from domain. I can, at this time, have it up and running and hooked to domain.
What is the best way to remove it from the domain? If MS articles are referenced, please be ready to help interpret some of the article(s) explanation(s).
