Hi Al! Yes I followed it. Only difference is that I used my own CA, not any third-party CA such as Verisign. I think you misunderstood the situation. Steps again! 1) I installed on Web server a Web server certificate through my own Enterpreise CA. 2) I exported this certificate named owa.mydomain.com with private key to a file. 3) I imported certificate from this file to ISA server on MMC > Local Computer > Personal store. 4) I imported also Root CA certificate (*.crt file) to ISA server. I need this certificate to trust Web server and to connect between ISA and Web server. I had no trouble with these configuration and installation. THAT was the first part. THe second part is also NO problem. Here are the steps that I followed: 1) I created a certificate FOR ISA server (Web Server certificate template). It is named exchange.mydomain.com. 2) I stored this certificate also on ISA server on MMC > Local Computer > Personal store. I hope you can follow me... Then I created a publishing rule for Web server. I used SSL Bridging for it: 1) I defined Web Listener and I enabled SSL port and selected the certificate exchange.mydomain.com for this Listener. 2) Then I went to BRIDGING tab on this publishing Rule and selected REDIRECT REQUESTS TO SSL PORT. Then also enabled USE A CERTIFICATE TO AUTHENTICATE TO THE SSL WEB SERVER. 3) (This step Important!!!) Then I clicked on SELECT button to select a certificate. THen I had the errorr message: THERE ARE NO CERTIFICATES TO CONFIGURED ON THIS SERVER. That is the problem! I hope, it is clear now for you what I meant. Best Regards Mustafa
