Not really, WINS is one way of resolving a netbios name to an IP address and the
reverse. The other ways are by lmhosts files and by broadcast (works only in one
subnet). With nss_wins, wins is now available for unix also.

That should have worked before anyway. If you can't ping your windows machines
by netbios name, and nss_wins is setup correctly, then the chances are that your
windows machines aren't setup for wins. You either need to do this manually on
each machine, or do it by dhcp by adding something like the following to
dhcpd.conf (inside your subnet "stanza":
~ option netbios-name-servers xxx.xxx.xxx.17, xxx.xxx.xxx.87;
~ option netbios-dd-server xxx.xxx.xxx.17, xxx.xxx.xxx.87;
~ option netbios-node-type 4;

No, as long as the box running wins has a static IP (even if it is by dhcp, but
you would then reserve it's IP based on MAC address).

You might want to check that you can find the windows machines by wins first,
before you check nss_wins:
nmblookup -U <IP of WINS server> -R <netbios name of machine>
If that works, then nss_wins should work.
