How to get IP address for the LAN computers?

I tried to convert the name some computers in the LAN to IP address.
However, the DNS code that copes with Internet names could not find an address for any computers in LAN.
Can anybody help me?

P.S. Sorry for my bad English

To resolve a local name, you must use a netbios client who works on UDP port 137.
Clearly the udp netbios packet is different from the one you used in DNS but you can find it in internet with “NETBIOS Name Service” or here http://tools.ietf.org/html/rfc1002

Thanks, I will try to write a NetBIOS client
