For various reasons a OU branch with a DC has to be disconnected from the rest of the forest and keep it isolated (without Internet connection)
We know the implications of losing the trust between the DC of this branch and the rest of DCs. However, I would like to know a couple of things:
- Does this have any other implications for the branch to keep on working for let´s say 2-3 months? All local hyper-v and virtual machines will keep on working? Can we update manually uploading to the local WSUS Server all Windows updates?
- What would be the procedure to bring this branch back to the forest? Restore the trust first of the DC to the rest of DCs? Will that restore the trust for each server within the OU or we do have to do it manually for each server?
Anything else we should take into account?
I have searched around but I haven´t found anything relevant
