The security certificate presented by this website was not issued by a trusted certificate authority error

How can i go about preventing these two errors below for our OWA?  If i click passed them it works fine but want to clean this up.

The security certificate presented by this website was not issued by a trusted certificate authority.
The security certificate presented by this website was issued for a different website's address.

I am currenlty running exchange 2003 with windows 2003 and AD 2003.  I have setup a CA on the excahnge server and issued the certifcate from there.

thanks

If you are using https://www.yourdomain.com/owa then your certificate needs to be named www.yourdomain.com.  If you don't have it named this way, then you need to rename the certificate.
The issue with the client not trusting the certificate means that you have not installed the certificate on the client.
Do yourself a favour.  Buy a 3rd party SSL certificate from somewhere like GoDaddy for $29.99 (for a 1 year certificate), and all your problems will go away instantly.
No errors, no installation of certificates on clients and no support hassles.

Click in your browser where it says certificate error.  In the next box click View Certificate, then install...you want to put it in the second group down in that list.

But to do that in Windows 8, you may have to right click on IE and run as administrator first.  In Windows 7 I had to do that.

well first the self signed certificate you are using needs to be recreated to reflect the subdomain of your mail server not of your domain. So if your mail server is mail.yourdomain.com your certificate needs to be generated for that domain it self and you will not get the:

error any more.

But to relieve yourself of: The security certificate presented by this website was not issued by a trusted certificate authority.

You would need to first get a certificate created for you domain by a security company. GoDaddy offers signed certificates, from them selves and a third party. Also the most trusted ones are VeriSign certificates. Then you would have to install it into your exchange server not the server hosting the exchange server.
