Thanks Peter for you reply,

but once again all that you mentioned are based on a user name and a password, so if those were stolen all the permissions to that exact user will be available to the one having the username and password....

i was looking for more security.....

thanks

Celerra does not support such features like MAC or IP-Address filtering.

There are many features to secure a windows fileserver, like Share Permissions, Folder Permissions, ABE, Windows Passwords ....

Sounds like putting some firewalls in place is the only way to get you the security you are looking for for windows clients.  Windows in general is a user/group based security system, just like any OS from a local perspective.  Although *nix has network and host based network access available.

You could look at using the windows computer account for access, but in my opinion that is less secure than a user ID.
