I have a question about OWA 2003 running on ISA 2004. Is there some type of software that can be installed on the ISA 2004 server and on a company "asset" (laptop) that when connecting to OWA 2003 that will identify the laptop as a company asset? I need to find a very secure way of publishing OWA to the Internet and our users getting there email over the Internet. Any suggestion, ideas or articles would be great. Thanks, John
