Using DNSCMD to export reverse lookup zone

Posted on 2014-01-29
Last Modified: 2014-01-29
I am using the following command to export DNS Reverse lookup zone to a file.

C:\>dnscmd DNSSERVER /zoneexport > c:\dnszones\

I do not get any error, but when I open up the exported file I see:

Usage: DnsCmd <ServerName> /ZoneExport <ZoneName> <ZoneExportFile>
    <ZoneName>   -- FQDN of zone to export
                    /Cache to export cache

Command failed:  ERROR_INVALID_PARAMETER     87  (00000057)

Check the required arguments and format of your command.

I wonder what I am typing wrong..

Any help will be very much appreciated

Thank you

The command requires filename at the end. your command is missing file name.

dnscmd DNSSERVER /zoneexport

I meant output file name, yes destination file name, avoid using zonename.dns as output file name, the default path of the output file is %systemroot%/System32/Dns directory and that can create problem if you don't provide proper path.

dnscmd DNSSERVER /zoneexport output.dns or

dnscmd DNSSERVER /zoneexport C:\dnszones\outputfilename.dns

Is the zone name correct? The command should export the reverse lookup zone
