I would have to go back and check but I think the limitation is that you can only have one certificate per web site (not IIS server, basically each new port or site with a unique host header).  So, as long as its a new site then you should be able to do this with no problem ... thisnk ISP, they host lots of SSL sites on one server.
If you need a second certificate for an existing site then I think you would have to set up a new site and then redirect once they arrive there and validate.

You can only have 1 SSL certificate per *IP*address*.  SSL handshake happens before the headers (with the host name) are transmitted, so you can't run several virtual hosts on the same IP with different certificates.

You don't have to install a 2nd network card, however you do have to get a 2nd public IP address and assign it to the card you already have (a network interface can have many IP's assigned).


In windows 200o server how can you add multipe Ip address can you tell me please

Go to network connection properties, select Internet Protocol TCP/IP, click Properties then click advanced.


sorry I forget to mention they have one Network card with ip address for Second SSL do I have to use another Globall Ip address to pr simply I can  add another address to  network and it will work

Are you sure about the 2 IPs?

If you are using a new certificate anyway then give it a try just using host headers.
The certificates are keyed to the site name so I would expect it to work with different host headers and not require a new IP for each one ... but hey, until I try it I can't say for sure ... if you try it let us know if it works.

In reading your question it raises the issue ... do you need a second SSL certificate, if so for what?  If it is just to secure an addition site running off the same server then you can do this with the existing certificate (well, most likely).
If you need to use a new domain name then yes, since the certificates verify the URL against the name on the certificate then you need a new certificiate for this.
