Configuring a Certificate for the Mediation Server

Topic Last Modified: 2009-05-22

The Mediation Server must be configured with a server certificate in order to connect to other Office Communications Server servers. The certificate is usually configured in the Certificate Wizard when you deploy the Mediation Server. If you want to change the certificate, you can do either of the following:

  • If you are logged onto the Mediation Server, you can use the Certificate Wizard to guide you through the process of requesting and assigning a certificate. For details about using the Certificate Wizard to configure a certificate for the Mediation Server, see Configuring a Certificate for Mediation Server in the Deploying Enterprise Voice documentation.
  • If you want to assign a different certificate to an individual server, view a certificate, or delete a certificate, you can open the individual server's properties and configure the certificate by using the Certificate tab. When you delete a certificate, it is no longer assigned to the server for TLS or MTLS, but it is not deleted from the computer. The procedure in this section describes the use of the Certificate tab.

Any modifications you make are only applied to future connections—existing connections continue to use the old certificate as long as the connection continues.

To configure a certificate for a Mediation Server

  1. Open the Office Communications Server 2007 R2 snap-in.

  2. In the console tree, expand the forest node, expand Mediation Servers, right-click the Mediation Server for which you want to configure a certificate, and then click Properties.

  3. On the Certificate tab, do one of the following:

    • To delete the current certificate, click Delete Certificate, and then click OK.
    • To assign a certificate to the Mediation Server, click Select Certificate. In the Select Certificate dialog box, in the list of certificates, click the certificate you want to use, and then click OK twice.
