Can you advise me whether to go with a client/server, or domain based OS, considering the scenario below. I have been asked by my wife (a high school math/computer teacher) to help her network an assortment of donated windows machines in their small computer lab classroom. I'll see that there is an NIC card & driver in each computer and use standard cat 5 to cable them to a hub with sufficient ports (presently there are about 8 computers but they may expand in the future to maybe 15). Then bind them to the correct protocol/s - Tcp/ip and Netbeui or ?, Client for MS Networks, File & Printer sharing. Problem is they dont want a simple peer to peer because the kids mess with all the settings and leave the hd in a jumble. It's out of control. Ideally the teacher has full control: 1. -To provide/prohibit access at each workstation. -To determine which programs are loaded. -To clean & restore the drive when the day is done 2. - To be able to demonstrate her lessons from her pc to the students on their pc 's. For example, if she's demonstrating a database program or doing a simple pascal programming exercise , they can all work on the lesson from their desks rather than gathering around her screen. - Control where they can store their data files, or perhaps they don't, and have to save them to floppies or cd? 3. At this time, Internet access is not a priority. Although I'd prefer to incorporate it into the planning. Not sure how,but maybe from the hub to a standalone router which will be connected to the telephone or cable feed into the building. Thank you for your anticipated assistance, Frank
