Hi Troy! I did it. No suscess. I want to notice here again: I have no problem with certificates for Web server if I bind them on Web Listener. I have only problem with the certificate binding of ISA server (on the BRIDGING tab of publishing rule). I created this certificate for ISA on Root CA and stored it on MMC > Certificates > Local Computer > Personal. And I imported also Root CA certificate to Trusted Root Certificate areaa on ISA. Any other idea? Best Regards Mustafa
