Total Internet firewall etc management tool like ISA

[samvb]

ISA 2006 is great tool but it is quite complicated and sometimes pain in the neck. Is there any alternative to ISA in windows 2003 alternative? My main options are manage connection to internet, block websites, filter websites and bandwidth management. Several tools that I can combine are fine as well. Any tips?

This is just my opinion because i have used it and I have seen some enterprise networks used this.

It is called Kerio Control - it has all the works even a little more stuff than ISA. There is a free trial if you want to test it.
