Ubuntu offers you an easy way to turn a desktop installation into a terminal server for your office or school to serve multiple diskless clients.
The LTSP-5 Terminal Server implementation that was developed in Ubuntu together with ltsp.org and debian, is now being adopted into most other distributions (Fedora, Gentoo, OpenSuSE). With Ubuntu Terminal Services you get the most recent and reliable Terminal Server implementation currently available on the linux market.
Recent studies have shown that using diskless Thin Clients in office environments saves on average around 50% of your power costs. Maintenance, user and software management of a Terminal Server is centralised on the server instead of maintaining individual work places. All data is stored on the server, so if client hardware breaks you won't lose data. Hardware replacement is as easy as changing a lightbulb, allowing users to carry on with their work in minutes.
To use Ubuntu Terminal Services during Ubuntu install use the Ubuntu Alternate CD for installation, hit F4 at the bootscreen and select "Install a LTSP server" from the pop up "Modes" menu. If you use a machine with two network cards, your server will work directly out of the box (in the case where you have only one network card it will tell you what to do).
