2 SSL certificates for 1 domain hostname?


I'm still very much learning about SSL Certificates, so I would like confirmation on the below before I purchase another:

Can 2 seperate SSL Certificates (from 2 different companies (i.e godaddy.com and rapidssl.com) operate for the same hostname (i.e mail.mydomain.com?)

My understanding was that the certificates references known and trusted certificate publishers, so as long as the 3rd party cert was from one of these it wouldn't be a problem.

We currently have our IIS 6.0 certificate up for renewal and have been locked out of our account and need the main contact to re-activate which is proving to be problematic, so before it expires I'd just like to get a new one as we will have to revoke and replace it with IIS 7 anyway.

We have recently upgraded from SBS 2003 to SBS 2008, am I correct in thinking that we need an IIS 7 cert now? Again, I'd just like confirmation for peace of mind please!

Many thanks!

Yes, you can have two different SSL certificates from two different provides for a single name.  You can only associate one certificate with a given program on a given machine at a time... but it sounds like that won't be a problem for you.

(So, for example, I've had certificates in the last month or so on a server for server.domain.edu signed by Geotrust, then added a second certificate for sameserver.domain.edu to the server from godaddy.com (or from my internal CA).  During my maintenance window which might be weeks later, it then just takes a second or two to change the IIS binding to use the new certificate.)
