I have found through experience that using any of the fine products of either PC-cillin or Fix-IT and using for a software firewall Zone Alarm Pro will pay dividends! Caveat...(AND this is a BIGGIE): these hearty reccommendations should only be utilized for home networking or small business networks of no more than 10 clients. If you want to go enterprise, I still reccommend Fix-IT enterprise editions, but it will cost... BUT: Fix-IT enterprise suites are extremely "no-brainers" to configure, even a pinheaded chimp can configure it! Anyway, I suppose it all boils down as to your need...and, of course, appropriate trade-offs... Please visit the On-Track web page for further information...it can't hurt!!!
