Lync 2013 cert error only when sharing PPT

Hello,

We have an otherwise functioning Lync 2013  server/client installation, but sharing out PowerPoints has resulted in a error "There was a problem verifying the certificate from the server. Please contact your support team" (see attached too). I have researched this here http://goo.gl/inDh9L, which has not worked for me. I think I need to see the cert requirements for this operation, as everything else has been working for a while. Point me in the right direction?

Thanks!!

Do you have office web apps server deployed?
If yes then the url set for web apps has to be on the cert installed on the web app server which should be trusted by the client endpoint..

I do - it works well (no cert issues) for whiteboard sharing, surveys, desktop and application sharing. Just not Powerpoint!

I did double check the cert that the OWA server is putting out, and it does specify the same URL as is listed in the Lync Topology builder.

Hi Mai Ali - thanks for taking a peek! That was not it though. I can go to http://computername.domain.local/certenroll/caroot.crl and am able to download the CRL file. And I did double-check those settings are in place (i.e. SSL is not required).

As a followup, we are on the right track - I also saw that in our CAroot cert (in the certificate chain), we have an old entry for the last certificate server in the CRL distribution point field. So the scope of this issue is very different now. I'm not sure where to change the caroot cert and if I do, will that mean I will have to reissue all the certs in my domain?

I figured out how to remove the old CA and reissue the cert, so that was part of it, but we also had a networking issue that we had to iron out, where people off-domain and via VPN were not being routed to our Front End correctly for the address our topology was asking them to use.

The other answer pointed me in the right direction, but we had to get our networking right first.
