Are you there is no firewall software blocking answers to the request ?

Yes, workstations register the username with Netbios to be able, for
example, to receive messages directed to a username. This is also why
you should never name a workstation after the username, you may end up
in conflicts.

Netbios names can represent a number of things as they represent
services not merely machines. In a busy network you should find user
programs registering their own names sometimes too.

If this machine does not have samba, then you do not need to restirct
samba4wins to an alias, you can just use the primary interface.

The ip alias trick is used to let samba3 run it's own nmbd daemon on the
same address of smbd.

I'd make a network trace and see if the request goes out on the wire and
if any answer returns.

Simo.
