As other's have said the NetBios name to IP address mapping is rather complicated. So rather than dwell on it, i'll try and help with your original request, pinging the windows clients from linux.
Firstly a little info on NetBios names, etc. When two computers power up on the network, each has to announce itself to the windows network. Depending on the OS, and it's presence in the network topology (server, workstation, PDC, etc.) each has a certain value. Win9x falls to the bottom while NT Server as PDC is top! Tha aim is for the machine with the highest value to become the "Browser Master". If 2 machines of the same type try, then the first one there wins, or if the 2 come on at the same time, they back off for a random period of time and retry, where again first one to get there becomes the master. The "Browser Master" then caches the NetBIOS names for the network.
Anyway, to cut a (very) long story short, while ping isn't so easy, there is another utility to resolve NetBIOS names to IP addresses and vica versa.
nmblookup can query the WINS servers, or even a PC.
e.g.
nmblookup -A 172.43.56.112
will give me the NetBIOS name. while
nmblookup -U server -R 'name'
will do a name query on a WINS server if you have one running.
Do a man nmblookup for more info.
On windows, there is a way to do a similar thing, but I can't remember how just now.
Hope that's of use.
