Have you ever heard anyone say NFS is insecure? One of the reasons for this
is that lots of systems are setup so that if I am root on my local machine,
the NFS server assumes I can access root's files on the remote machine...
Windows NT domains, however, are supposed not to suffer from the same
problem. This is because, in order to access a share, you must be
authenticated by the domain server. The only way to authenticate with the
domain server is to log on with your username and password. Simply rsh'ing
to a machine isn't enough, the domain controller will not trust you. Hence
you will not have access to any network shares as it won't believe who you
say you are.
