I help out at an after school project and we are trying to ban a certain group from

They are (or can be) in a specific Active Directory group and we are running Windows Server 2003.

ISA Server costs around $1600, which is probably a bit much for the current budget. Does anyone know of an alternative that will let us filter sites by AD groups?

Thanks in advance, Chris

You could use the good old well known Squid proxy for this.

Here is just one howto with config examples. Google will give you a lot more in no-time.

You might look at Untangle. You would have to purchase Active Directory integration, but it's not expensive. You'd also need a spare box to throw it it basically becomes your edge router. It'll do firewall, web filtering, virus scanning, etc out of the box.

use a router which support URL filtering. Draytek is a good low cost example.
