1692 but it can be a pain as it means "net view" needs to use a password

1697 are rejected. This is the default.
1699 "MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
1700 are rejected, unless the username does not exist, in which case it
1701 is treated as a guest login
1703 "MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
1704 are treated as a guest login
