Logging on to NT4.0

Your shares are probably setup to allow access to everyone (the default for NT4 when you create a share). If this is the case then you need to change the permissions to 'authenticated users'. I would also check the security settings.

Well, a quirk of NT is that if the local user name and password is the same as the domain user name and password, you will get some access to the network because NT will see the user SID as valid. You would probably be able to access any shared resources that were shared strictly on the basis of user rights. They should, however, be getting an error message saying that the domain (the one that is actually listed on the login screen) is not available. Unless, of course, the domain name that'sactually on the login screen exists somewhere and there is a trust relationship between the two domains. In that case, they would be logging on to one domain and accessing the other domain by virtue of the trust relationship between the two domains. Hope this helps!
