I mentioned "hardware solutions" in my email... however, the cost of these hardware appliances is pretty high. In theory, you can do the same thing with a properly configured linux server at less than half the price. Of course... the money is in the configuration ;-) Sincerely, Jason - Origi

There are a number of very effect "appliance" style solutions to doing this. Please have a look at RadWare (WSD) and F5 Networks (3DNS); I have had great success with both companies. The bonus is that these solutions can automaticly determine if a server is up. Ken Seefried, CISSP :yegon wr

It would depend on how popular the sites hosted on the servers were. If you set a the times to be too low, say 1 minute, then every time someone looks up the DNS records, then BLAM... your dns servers are hit because things aren't cached anywhere. So I would use something like an hour (we use this

Do they all have their own IPs within your lan? You could limit bandwidth on a per-IP level if you want. That way, if they decide to play with napster and stuff, they will then have to suffer with low webpage loading, slow email, etc. That might encourage them NOT to use those types of programs any
