warriorfan808, here is a fun option/project - first, tell your boss not to be a tight-arse and give you a couple of dollars to go to a swap-meet and get an old computer, any low end pentium unit will do. Drop a couple of network cards and a healthy bit of RAM into it, 256mb + - this is important for filtering it is a bit memory hungry.

Now go visit http://www.ipcop.org or http://www.smoothwall.org and download the free iso of their firewall distribution. Load this onto the computer, it is very easy if you follow the instructions - 15-20 minutes tops. I know you didn't want a firewall option, but trust me this is fun and works.

Now thats all set up - slip on over the http://www.urlfilter.net and download the addon for either Smoothwall or IPCop, which ever one took your fancy and drop that on the box - place this computer between the Internet and office network and little Johnny has no more football or porn to look at

If you chose IPCop there is always Cop+, a Dansguardian addon to be got at http://firewalladdons.sourceforge.net/cop.html. But remember, Dansguardian loves RAM, so the more the merrier.

You can monitor where he visits from the very easy to read logs and add the sites as you find them on a very easy to update web interface you can even customise the blocking page and send a message that scares the pants off him

Instant firewall/proxy/DNS server for the office with filtering capabilities and with a bit of luck cost you nothing but your time, if the right bits are found lying around - now the boss can sell that hardware firewall and take you out to lunch for being the bright and ingenious individual you have shown yourself to be.

Whatever your solution - good luck.
