Two warnings in the event log - event ID 26 indicating 2 different certificates with different thumbprints will expire. I run mmc and personal certificates on the local computer and the two certificates are listed.
One is Issued to Sites, Issued by mydomain-SERVER-CA, Intended purpose Server authentication, template is Web Server.
The other is Issued to SERVER.mydomain.com, other info same as above.
We do have a Godaddy certificate good until 2015.

Can I remove these? or should I remove them? If so, from the personal store or some other way?

If you run the fix my network wizard, it should correct the certificates.
They are used by SBS internally, so if you remove them, they will need to be replaced.

Most SBS servers will have three certificates listed - the Sites one, a self signed issued to the server's FQDN and the trusted commercial one. That is perfectly fine.

That makes sense, I won't be able to run the wizard for a week or so but they won't expire for another month so looks like I have time. Thanks!

I ran the fix my network wizard, the error has not gone away and it's past the time for the certificate to expire. Everything seems fine so I'm not going to pursue this any farther.
