You can also install ISA Server after you upgrade to Windows Server 2003. However, the packet filter extension driver in the release version of ISA Server is incompatible with Windows Server 2003, and it is blocked from loading during installation. During installation, you can safely ignore all error messages that are related to this issue because ISA Server SP1 includes a compatibility fix for the driver.
