I have a wildcard certificate and I would like to set up multiple websites using the certificat. When I set up the first site "mysdomain.com" I was able to start ssl using port 443. I then created the second site "xxx.mydomain.com" and I ran the adsutil.vbs and was able to start the website. I then created a third website "yyy.mydomain.com" and ran adsutil.vbs. When I tried to start the site I got the following error.
IIS was unable to start the site. Another site may already be using the port you configured for this site. Please select a unused port for this site.
