We have 2 lync front end servers, with a internal certificate from our internal ROOT CA and a Public CA certificate.
Nothing was changed, we have noticed that when we launch lync control panel we receive a cetificate error "the name on the certificate is invalid or does not match the name"
When we check the certificate details it shows the Public SAN cetificate and if we continue it gives a access denied error.
All the services are up and when we run the deployment wizard it shows all the certs as valid and assigned.
We tried unassign and reassign the certificates and reboot, still it gives the same security alert and cert error.
The Control panel opens up when we try https://servername.domainname.com/cscp or https://poolname.domainname.com/cscp from IE
