+ 1 Votes NSLOOKUP? terencerabe 2 years ago How do you know the machine you're successfully pinging is the DNS server? Just because the PING succeeds (Internet Layer) does not mean that the DNS service (Applicaiton Layer) is running or even installed on the maching you're pinging. What you need to try next is the NSLOOKUP command. At the command prompt just type NSLOOKUP and hit enter... post what you get back here.
