Exchange security certificate error and OWA

Last Modified: 2012-06-27
When using the OWA to access email the intial page pops up an error window: Security error: Domain Name Mismatch. You have attempted to establish a connection with mail.MyDomain.com. However, the security certificate presented belongs to server.MyDomain.com.

If I click ok I can access my email.

How do I resolve this little problem? DO I just go into the exchange servers certificate and edit it or do I have to create a new one?
