This is a old samba bug thats been known about for a *long* time. I
think sombody finally fixed it in recent 2.2. Basically, Samba doens't
re-register, it assumes that the WINS server is stable and doesn't loose
entries. On a similar issue, Samba's wins server now keeps its entries
across a restart.
