I have SBS 2003 with ISA Server 2004 SP 1. I have two servers ISA Server on one and SBS 2003 on the other. I am able to access the web server with no problem internally typing in the domain.com/exchange or domain.com/remote. I have published the secure server and have the certificate. when I try it externally I have a problem. i am unable to access email or remote web workplace externally, i get the main page fine if i just type in https://domain.com/remote or https://domain.com/exchange I get the prompt for a certificate and when i click yes or even view and then install, i get page cannot be displayed. I have been trying to figure this out and not sure whant the problem is. Thanks in advance for you help.
