Configure Certificates for Stand-alone A/V Conferencing Servers


Topic Last Modified: 2011-10-28


When you run the Certificate Wizard, ensure that you are logged in using an account that is a member of a group that has been assigned the appropriate permissions for the type of certificate template you will use. By default, a Lync Server certificate request will use the Web Server certificate template. If you use an account that is a member of the RTCUniversalServerAdmins group to request a certificate using this template, verify that the group has been assigned the Enroll permissions required to use that template.

To successfully complete this procedure you should be logged on to the computer where the Lync Server Deployment Wizard is installed as a user who is a member of the RTCUniversalServerAdmins group or have the correct user rights delegated. For details, see Delegate Setup Permissions. Depending on your organization and requirements for requesting certificates, you may require other group memberships. Consult with the group that manages your public key infrastructure (PKI) certification authority (CA).

Each stand-alone Audio/Video (A/V) Conferencing Server requires a single default certificate. For details about the certificate requirements, see Certificate Requirements for Internal Servers.

Use the following procedure to configure the A/V Conferencing Server certificate. Repeat the procedure for each A/V Conferencing Server.


The steps of this procedure describe how to configure a certificate from an Internal Enterprise Root CA deployed by your organization. For details about obtaining certificates from an external CA, contact your IT department.
