Recovering a DNS database from registry/MMC
** Question: How can I recover a DNS database from the registry in the Microsoft Management Console? Answer: If you are using Active Directory-integrated DNS, then your DNS information is stored in Active Directory itself, and you'll need to perform a System State restore to retrieve it. If you are using standard primary and secondary zone files, these are stored in the %windowsroot%system32DNS directory and would need to be restored from there. **
