There is a problem with this website's security certificate - serviceunavailable

Hello,

I bought an SSL certificate for my server (Windows Server 2003, IIS
6.0).

Server included already a web site with SSL certificate, so I created
a 2nd web site with different IP and different SSL certificate and
different application pool that is running.

When I try to access the 2nd web site I get a message from IE "There
is a problem with this website's security certificate." If I click on
option "Continue to this website (not recommended)", I get error
"service unavailable"

What could be the problem ? 1st web site is running without problem on
this server.

Thanks a lot in advance.
