Certainly the kernel panic wasn't the fault of Samba running WINS, but
the consequences point us to the limitations of Samba.
Even a single network disruption between WINS/PDC and the rest of your
network can cause trouble similar to WINS/PDC kernel panicking.
To prevent such cases, where networks are separate (i.e. in different
cities) but use a single user database (in LDAP), I just set up PDCs
instead of BDCs (they don't see each other via netbios anyway), and each
of them is acting as a WINS server.
I find it much more resistent to such failures.
