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.
