Hi all, I'm trying to follow the steps listed in Tom's book (the first one) on pages 644 - 647. I am able to create a Certificate using Certificate Server on one of my systems, then I can export it. So I think I'm doing that part correctly. I am able to do the import Certificate on my ISA server, but when I get to the part about Configuring the Inbound listener, if I edit the listener, and click on the check box for Use a server certificate to authenticate web clients, the field doesn't become enabled and I get a message that there are no certificates installed. Did I miss something ? Thanks. Nick. ____________________ Nicholas Palmer KCI Computing, Inc. (nick@xxxxxxxxxxx) 310.921.6222
