SBS 2003 with ISA - self signed cert worked fine for years, but wanted to add RPC over HTTPS. Purchased and installed Go Daddy SSL cert for this. Installed cert, bound cert to Default Web site. Now, still cannot connect using RPC over HTTPS, and remote access via "https://mail.mydomain.com/remote" says "Error Code: 403 Forbidden. The server denied the specified Uniform Resource Locator (URL). Contact the server administrator. (12202) ". Also trying to set ISA to allow cert by running IE Connection Wizard get response: No Certificate has been requested for the default Web site in IIS. even though it has. Does anyone have any ideas. We are going to upgrade this server within a year and use SBS Server 2011 with a hardware firewall instead of SBS, but would like to make this work for now.
