Server filter to apply to the curriculum PCs
We currently have our ISA server in place, and we believe that our server is aging badly. Now that we have some extra funding, we wont be switching over to linux (as is my understanding) so as such, sticking with Windows. So aside from our ISA server which is touch and go at best, can you guys suggest a good filtering system that can do the following.
Import filters from ISA Server
Allow us to add websites adhoc
Allow us to set specific groups (basically different filters for different year groups) which would take its info from Active Directory.
Any help would be greatly appreciated.
