Issue with sharing a whiteboard in Lync and certificate issue with webcon01

Some of our users are having issues seeing someone's shared whiteboard.  It boots them out and they get the following in their uccapilog.   Ultimately imo I think it is due to when we go to webcon01.domain.org, it has a certificate error.  I believe this is due to the webcon01.domain.org name not being the SAN part of the certificate.    If we get a new certificate, how can we apply it to the webcon01.domain.org url?

Topology wizard takes care of most certificate SAN entries that are required based on the topology you built.  webcon01.domain.org needs to be in as a SAN entry if it is a Simple URL.

Well, looking at the server, I see multiple certificates (looks like someone might of got cert happy).  One of them has webcon01 as a SAN entry and another cert does not.   When I go to https://webcon01.domain.org and download the cert, it is pointing to the cert without the webcon01 SAN entry.    How can I get it to point to the correct cert.

Thanks

This issue has been resolved.  It was a certificate issue on the local computer.   I deleted it and added one from a working machine.  That fixed the issue.
