limit internet access

I am trying to find a program I can use to limit internet access to only a few sites. This is for a business and so far I can only find blocking programs. Anyone know of a program that will block all but approved sites?

Welcome to Windrivers smghou

content advisor in IE can do this

If its Vista there is an awesome control in the control panel called Parental controls.

Most businesses use Websense. It is a software but it shuts down every site and you tell it what you want turned on. I know that the US Army, Some National Guards, Radio shack all use this program.

If your trying to block websites on multiple computers you wont be able to use the parent control on Vista unless you want to go to every computer and set it up and content adviser is going to be the same way. Programs like net nanny have to be set up on each computer and take up recourses.

For business use I would suggest a server program not an individual user program. A server program will also allow you to add more computers with out having to setup the blocks on them. A server program will also block peoples personal computers from going out on the net. ( I know personal computers are not suppose to touch work networks but it happens all the time)

Thanks for the replys. Probably should have told you that there is no server on the network just a router on a T-1. About 40 desktops all running XP. Even though it is a royal pain I will need to load what ever program I use on each machine.

In which case you want to use parental controls and have done with it!
