SSL Certificate Mismatch in IE 7+, OK in Firefox 3.6+

Question

Hello,

We have a site www.name1.domain.com for which we successfully created and implemented an SSL cert. We then added another site, www.name2.domain.com, and are seeing some strange behaviour in IE7 and IE8 (surprise!).

Basically, IE7,8 reports a mismatch of host name when we go to https://www.name2.domain.com/ . When I add and view this cert in IE for this domain, the host name is incorrect, but belongs to the older host name, i.e., www.name1.domain.com.

Firefox doesn't have this issue, and picks up correct host name www.name2.domain.com for the second site without issue.

Any ideas why IE is misbehavin (apart for the sassy ones (-: ) ?

Thanks!
