Event Message:

DNS server is not root authoritative and no cache file specified. A cache file must be specified when the DNS server is not authoritative for the root domain. The cache file must contain NS record(s) for root DNS servers and corresponding A record(s) for the root DNS servers. Otherwise the DNS server will be unable to contact the root DNS server on startup and will be unable to answer queries for names outside of its own authoritative zones.

User Action:

If you are not connected to the Internet and you deleted and recreated the cache file to provide a list of host name to IP address mappings for your private network, then verify that you have saved this new cache file in the Systemroot\System32\Dns directory. If you are using a boot file that has been imported from another DNS server, open the file with Notepad and verify that the path specified in the directory command identifies the Dns directory. Also, verify that the cache file is defined in the boot file (cache . cache), and is not commented out. If there is no cache file located in the Dns directory, you can obtain a copy from ftp://ftp.rs.internic.net/domain/named.cache. Prior to downloading a copy from Internic, check the Backup subdirectory in the Dns path to see if there is a copy of the cache file that you can restore.
