Kevin, Funny you should mention this. I looked at this problem--let me phrase it as 'how do I find the "NetBIOS name of a machine give its IP'--and didn't get to the solution. However, here's what I found. The NetBT protocol for looking up names uses the same packet format as DNS, but uses different "commands" and of course uses a different port. The 'Status' command asks a node to report what 'names' it claims to have (which make be group names or node names). I wrote a piece of code to make this request but got stuck because machines wouldn't report their name unless I already knew it and stuck it in the right place in the protocol. Later, however, I discovered that NT and win95 has a program nbtstat.exe which is able to do this. Now all that remains is to sniff the packet and find out what's in there and then add this to my c++ code. If you'd like the code let me know.
