IT:AD:IIS:SSL

In INETMGR, install the server's cert:

• On the Server node (note: parent node to Application Pools/Sites)
• Select Features
• Select Server Certificates
• Add the cert

Then adjust the site's bindings:

• Select the Site note
• Select Site Bindings Add https/443, and select SSL certificate.

Get the Server Cert's Thumbprint.
I don't know how to do this from the command line, so you have to use MMC to nav to the cert, than click properties, then get the Thumbprint, then remove the spaces...

Get a Guid
Try http://www.get-a-guid.com/ -- but remember to wrap the result in curly brackets.
Or try http://www.makeaguid.com/

Once you've got all that try something like the following:
netsh http add sslcert ipport=127.0.0.1:443 certhash=6e5cf0d866896f14d6f745e90558e26aa6d1ae9d appid=2859db43-fbb1-433a-a47b-b6546c248ae2
The parameter is incorrect.
netsh http add sslcert ipport=127.0.0.1:443 certhash=6e5cf0d866896f14d6f745e90558e26aa6d1ae9d appid={2859db43-fbb1-433a-a47b-b6546c248ae2}
SSL Certificate successfully added
