At work there are about 40 PCs. I want to block all the websites and only allow a few Domains/Websites for operators. A few operators can access anything.
I want something quick and easy so I can filter the Block/Allow websites for all computers from one main computer, like a server or something.
Windows Vista Home and Windows 7 Home are installed on the PCs. Is there any software can do this?
PS: Please don't answer about Microsoft Windows Server OS..
