Hi Lorenzo
The RFC documents are the best references available about DNS and almost anything else related with the Internet.
RFC 1034 covers basic DNS concepts and the protocol inner workings. It can be found here:
http://www.zytrax.com/books/dns/apd/rfc1034.txt
Sometimes the RFC documents are somewhat difficult to read, so I would suggest you first grab a copy of some TCP/IP book ( Comer's Internetworking with TCP/IP, Stevens' TCP/IP Illustrated, etc.) and then return to the RFC documents if something is missing on the book.
Regards.

Hi Lorenzo,
If you're doing basic DNS fault finding, then NSLOOKUP may be of use to you.
It runs runs from a windows command line. There are a number of switches to it, depending on what you want to do.
Just type 'nslookup' from the command line, then enter the hostname you're looking up for the resolution. The'?' gives you the various switches you can try.
HTH,
Mark
