I have a server which is hosting a domain named abc.com . I have an SSL certificate installed for this domain on server and abc.com require SSL. Now I have a sub domain say sub.abc.com which is secured by another SSL certificate.
Now this is what I did to bind. Clicked the main site abc.com in IIS and opened bindings. Now in bindings, I added https and for IP Address I gave All Unassigned. For SSL certificate I selected the SSL cert for abc.com.
Again for the sub domain binding I followed same steps but under IP Address I gave the IP (19.xxx.xx.xx) of my server. Under certificate I picked the certificate for sub.abc.com.
Now on a browser if I open sub.abc.com its working fine. But if I load abc.com then the site is loading with warning and its displaying the certificate of sub.abc.com instead of abc.com . In bindings I can confirm that I have mapped to correct certificate.
Not sure whats going wrong here. Any help highly appreciated.
