Subject: [exchangelist] SSL Bridging and Certificates

In my test network I have installed ISA 2004. ISA is not the domain member
in my enviorenent (Windows 2003 Server domain).
The OWA server which I want to publish is a domain member, and has its own
certificate from Windows 2003 Enterpreise Certificate Authority.
I want to publish my OWA server by using SSL Bridging. 
1) I know that I need one certificate for my OWA server and to export it to
ISA server. I did this also.
2) I imported also Root Certificate of CA to my ISA server.
3) Second step is to install a certificate for my ISA server. I requested a
certificate for ISA from Windows 2003 Enterpreise Certificate Authority and
installed it under MMC Certificates (Local Computer) on ISA Server.

I published OWA server with ISA wizard and bound a Listener to the external
NIC of ISA. I opened the tab BRIDGING under Properties of this new
publishing and enabled "Redirect requests to SSL port" and "Use a
certificate to authenticate to the SSL Web server". BUT I cannot select any
certificate if I click on SELECT button. THen I have an error

What is the problem? Why I cannot select this certificate on the BRIDGING
tab? But I can select the certificate for my OWA server on the Listener tab.

Best Regards
