Hi Tom! 1) I cretaed a certificate on Web server named owa.mydomain.com. I exported it to a file and then imported it to ISA server. I need this certificate because of SSL connection between ISA server and Web server. - I created a second certificate (also Web Server certificate template) on ISA server. I need this certificate baceuse of SSL conncetion between clients and ISA server. That is the SSL Briding with two different SSL connections (Clients to ISA and ISA to Web server). Or not? Best Regards Mustafa
