Hi,

If the root domain controller goes offline due to hardware failure, what would happen to the whole tree (ie, child domain, OU etc)?

Please advise

Chances are the individual child domains would continue to function. However, domains would cease to communicate with each other, and AD would cease to replicate. Unless the root DC were brought back online quickly (preferably before the next scheduled AD replication), your forest could become unrecoverable.

This is an excellant reason why you really need a secondary DC in AD, especially at the root level. If the operations master fails, any other DC at the same level could assume all theoperations master roles.
