So i have lost two child domains and an exchange server today.
CHILD3 - CHILD4
So i have lost child 3, which had a child domain of its own child 4, the servers are physically gone, we have 0 backups.
i jus tneed to ensure that we maintain child 1 and 2 and main domain functionality.
i dont want to be loosing any more emails etc
each domain has its own exchange server.
my question is where do i start?
i need to remove child domains 3 and 4 i would normally do this by dcpromo but obviously that is not an option?
im server 2008 all round with the odd member server being 2012.
i inherited this system with no documentation so im in real need for some help.
i was lookng here https://support.microsoft.com/en-us/kb/230306
but as step 2 says "Verify that all servers for the domain have been demoted."
i am not sure because obviously they have not been demoted they are just gone.
any help will be greatly appreciated
