Re: DNS query - Nslookup

The first message means it cannot find a PTR (Domain Pointer, maps an IP
Address to a Name) record (in a Reverse Lookup Zone) for 192.168.0.YY,
and the second means it cannot find a PTR record for XX.

Which begs the question, do you have a Reverse Lookup Zone for
"192.168.0.x Subnet" or 0.168.192.in-addr.arpa (depending on your view
settings)?

If you don't, create one and set up as Primary Active Directory
Integrated with Secure Dynamic Updates enabled, then run "ipconfig
/registerdns" on your two DCs to have the first couple of PTR records
appear.

If you have one already, does it have Dynamic Updates enabled?
