We have a single SSL certificate called aac.thetest1.com from GeoTrust Extended Validation SSL CA - G2

but it has two DNS entries in the Subject Alternative Name called:-

qac.thetest1.com
aac.thetest1.com

I need to apply the certificate to two different websites on the same server, using the same IP address and same port 443, e.g

QAC - has qac.thetest1.com
WebApps - has aac.thetest1.com

but I am unable to do so as it complains that the port number is already in use.  What do I need to do to allow these website to use the same SSL certificates on port 443 ?

Thanks

There are lots of different ways, but here is my personal favorite.
Open the mmc on the server
run - mmc.exe - certificates - local computer
open the certificate with the san names
Click on the general tab and edit  the friendly name
Add an Asterisk (*) infront on the friendly name.

Now go to Inetmgr and create the binding for each site using host headers and ssl to the same ip addres.

This used to work for me.

If you are having issues here are some other ways to do this.
