Suppose I have a root domain of and a sub domain of  What would happen to the domain if the DCs for were removed/switched off?  Would the sub domain carry on working, or would they screw up because the root domain they hang off doesn't exist any more?  This is more a hypothetical question than a real situation I have.

Many thanks

    the should still work, if you are directly connected to that domain. you wouldn't able to find anything on though. It also depends somewhat if you have a DNS server running on and how that dns server is configured.

    the sub domain will definitly die, not yet but soon.
    in the root domain, there are all forest FSMO roles held. if they are missing, no shema changes will be possible.
    also no domain naming master is present.
    Replication will also have dfificulties to handle a non existant root domain.
