Linux allows users to create an easy to manage network. Consider this with NFS (network file system), NIS (Network Information system) and DHCP (dynamic host configuration protocol) one can setup a lovely roaming profile system, where all the user information is stored on the server including his desktop. So the user can technically sit on any computer in the office and get his entire data and desktop. This makes it convinient for the users. And from the administrators point of view they need to manage just the servers to control the entire data backup, maintainance etc. Linux also has a wonderful system to allow remote access. One can use SSH to access the entire system via a text based secure shell or even use X-Windows for those who prefer a GUI to access a system remotely.
