The DNS server could not find or open zone file dns\cache.dns. in the %SystemRoot%\System32\Dns directory. Verify that the zone file is located in this directory and that it contains valid data.

I am getting this message logged. I'm new to DNS. HELP!!!!!!!!!!


Thanks,

Look in \WINNT\System32\DNS and see if there is a CACHE.DNS file
there and see if it can be opened (check file permissions, etc.)

If not, you probably just need to restore it. Look in the \Samples and/or \Backup
subfolders for a copy. If all else fails, you can download the file from InterNIC
here: ftp://ftp.internic.net/domain/named.root -- rename this file or just copy in
the text.

CACHE.DNS contains the "root hints" that allow your DNS to locate root
name servers on the Internet. If you are using your ISP as a forwarder,
root hints aren't essential, but it is better if you restore it. (If your DNS is working
to find public names even without this file, that is the reason.)

If you are not Internet-connected, you can just create an empty
CACHE.DNS, or adjust the DNS server properties not to try to load root hints at all.

Click to expand...

The cache.dns file maintains a list of root servers that the name server
can contact when attempting to resolve names outside of it's own local
knowledge. The file is supplied with all Windows name servers by
default. It would appear that the file has been deleted (or at the
least, the name server is unable to read the file due to corruption or
inadequate permissions etc).

Simply copying a cache.dns file from another name server into the
%windir%\system32\dns directory should remove the error.
