Is this a SBS server? If yes, rerun the ICW (Internet Connection Wizard).

Yes, self-signed certificate must be created on Exchange server. If you have a local Root CA in the domain then both servers are involved in creating a self-signed certificate.
It starts within Exchange server: Open EMC, go to Server Configuration, select the server instance and, in the Action pane select New Exchange Certificate.

However, I will strongly recommend purchasing an external certificate from a trusted CA. There are many advantages of having that, with one of them: securing SMTP e-mail traffic with the other mail servers in the world.

Sorry, I assumed that it's an Exchange certificate.

What is the certificate used for? Do you have local Root CA? How was it created on first place?
