1492 password to be rejected or allowed in as guest? WinNT rejects them
1493 but it can be a pain as it means "net view" needs to use a password

1498 are rejected. This is the default.
1500 "MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
1501 are rejected, unless the username does not exist, in which case it
1502 is treated as a guest login
1504 "MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
1505 are treated as a guest login
