I have a Microsoft Windows Server 2008 R2 SP1 box running IIS 7.5 with two HTTPS sites. The server also runs Exchange 2010 so the Default Web Site uses HTTPS and i have another site which should also use HTTPS. I have tried the following: https://www.sslshopper.com/article-ssl-host-headers-in-iis-7.html and still receive the error "This Web site cannot be started. Another Web site may be using the same port" when attempting to start the second of the two sites at a time.
I have also had a look in the applicationHost.config file and saw the following the Default web site uses the default HTTPS binding (*:443) and the second uses www.domain.com:443.
Any help would be much appreciated.
