Re: Blocking "linked" web sites

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Not sure what the big deal is here. I have lists of Allowed - Destination Sets for
groups of users (Client Address Sets), and I just Deny everything Except the Allowed sites and
redirect to appropriate local .htm pages listing what rule blocked them. I do
have explicitly Denied - Virus/Spyware sites I let noone visit etc.. I schedule this
stuff up and down too. What is the issue ?
