Configuring Certificates for Application Sharing Servers

In a Standard Edition server deployment or an Enterprise pool in a consolidated configuration, the Application Sharing Server is collocated with the Front End Server, so the Application Sharing Server uses the certificate configured for the Front End Server. For an Enterprise pool in an expanded configuration, you must configure the certificate for the Application Sharing Server separately.

This certificate is usually set up in the Certificate Wizard during Standard Edition server or Enterprise pool deployment. If you want to change the certificate, you can do either of the following:

You can use the Certificate Wizard to guide you through the process of requesting and assigning a certificate. (You can launch the Certificate Wizard from the Available taskspane in the Office Communications Server 2007 R2 snap-in for Enterprise Edition servers and in Computer Management snap-in extension for Standard Edition servers. You can also access it from the Office Communications Server 2007 R2 installation media.)
If you want to assign a different certificate on an individual server, view a certificate, or delete a certificate, you can open the individual server's properties and configure the certificate using the Certificatetab. Deleting a certificate causes it to no longer be assigned to the server for TLS or mutual TLS (MTLS), but the certificate is not deleted from the computer. The procedure in this section describes the use of the Certificatetab.

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 an Application Sharing Server

Open the Office Communications Server 2007 R2 snap-in.
In the console tree, expand the forest node, and then do one of the following:
- For an Enterprise pool, expand Enterprise pools, expand the pool, right-click the server, click Properties, and then click Application Sharing Properties.
- For a Standard Edition server, expand Standard Edition servers, right-click the server, click Properties, and then click Application Sharing Properties.
On the Certificatetab, do one of the following:
- To delete a certificate, click the certificate, and then click Delete Certificate.
- To assign a new certificate, click Select Certificate.
If any certificate setting on the new certificate other than the expiration date is different from the corresponding setting on the old certificate, restart the Office Communications Server Web Conferencing service for the change to take effect for all connections.
