The Internet Connection Sharing/Windows Firewall service is disabled by default in Windows Server 2003 SP1.

But without any third party protocol plugins, is it needed for just running the Windows Firewall in Windows XP SP2?Ĭase in point, I was working with a Windows Server 2003 SP1 Enterprise Edition server at school in a class lab.

It says it's to proivde support for third party protocol plugins for Internet Connection Sharing/Windows Firewall. Everything I did on my system seems to function just fine without the Application Layer Gateway service enabled. But I have read various reports online that says it's absolutely needed and you will mess up your system if you disable it. I have disabled the Application Layer Gateway service, and the Windows firewall seems to work just fine.
