I have a windows SBS 2003 premium sp1 &nbsp;server running isa server 2004. &nbsp;I have a problem with this as I want to run isa in proxy and caching mode only and I cant seem to do it without isa interfering with windows firewall settings and group policy settings. &nbsp;I am thinking of removing isa 2004 and installing isa 2000. &nbsp;Would there be any issues with this and do I need to uninstall the MSDE instance for ISA 2004. &nbsp;My real problem is that i cannot get OWA to work remotely and I know that if I remove ISA 2004 it should work. What would be the best course of action. &nbsp;Bear in mind that I do not need the firewall capabilities of ISA server.<br />

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.
