Thanks to this list I now know enough about networks to be dangerous. :) I've recently gotten a couple of jobs setting up networks in small offices, and, while I have no trouble making things work, I wonder what the standard practices are for security and sharing files. I've never had occasion to work in such an environment. The usual situation is 2 or 3 computers sharing a broadband connection and virtually total ignorance on the part of the clients. OS is XP or 2000. I've been designating a single shared folder, which simplifies things and seems to work. I also install AV and Spyware protection. What else should I be looking at to do a thorough job? The NOSPIN Group is now accepting donations to help defer the costs of providing PCBUILD and our website.
