rid and schema restore

in the restore of ad ,it's always mentioned that avoid restoring rid and schema master .

How do i go abt it,by authoritative restore....

What are you trying to restore? Normally, you would only restore what is missing (OU's, Computer/User accounts, etc.).

If you've lost your one and only Domain Controller, then you have no choice but to perform a full restore...

hi

its a full restore.for objects recv normally authoritative restore would be ok.
