1721 but it can be a pain as it means "net view" needs to use a password
1723 You have 3 choices in the setting of map_to_guest:
1725 "NEVER_MAP_TO_GUEST" means session setups with an invalid password
1726 are rejected. This is the default.
1728 "MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
1729 are rejected, unless the username does not exist, in which case it
1730 is treated as a guest login
1732 "MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
1733 are treated as a guest login
