I have a client with 20 or so locations, in two different states. I have access to most of these through remote management, and all of them are within a few hours of driving distance.
The client needs a solution which will allow all websites to be blocked except a few that are needed to conduct routine business. The rest of the sites need to be blocked completely.
We tried Net Nanny on one of the machines as a test, and it worked alright, but slowed the system down to a crawl. I might also add that these are XP machines, with about 512 megs of RAM.
Someone mentioned to me that I should set up a BIND server, and have all the clients point to it for DNS information. This sounds do-able, but I would need a good site that would walk me through that process. I haven't done anything with Linux in a couple of years.
Thanks for the help!
