Content Filter Windows Server

[Guest iacon]

I am running windows server 2003 and want to add a content filter to

the network. I want something that is opensource (free) that is easy

to use and little hasstle to manage.

 

I want to config the proxy settings via windows server and have

everything run via the server.

 

I do have some spare OS X machines that I could use if they have a

better program avaliable, I have looked at squid proxy and can't be

assed with the amount of setup I need to do.

 

Can anyone point me in the best direction?
