dnscmdit doesn't actually show you semantically how all this gets put together, unless you fork it up like i did. here's the output of an incorrect command format:
/enumrecords 10.in-addr.arpa. 1.1
c:\>dnscmdif you notice, it appends the 10.in-addr.arpa zone name to the requested node name of 10.1.1. since 10.1.1.10 doesn't exist, it fails. moving on... i think in older versions, you had to include the "." following the zone, like "10.in-addr.arpa." instead of "10.in-addr.arpa". in either case, it works. you can see though, in the failed command context, it shows two dots trailing 10.1.1.10.in-addr.arpa. coffee time.
/enumrecords 10.in-addr.arpa. 10.1.1
DNS Server failed to enumerate records for node 10.1.1.10.in-addr.arpa.
Status = 9714 (0x000025f2)
Command failed: DNS_ERROR_NAME_DOES_NOT_EXIST 9714 (000025f2)
