Add Certificate for External Web Listener

In Forefront TMG, you can add a certificate for the external Web listener for Remote Web Workplace. If you have not installed the certificate on the Security Server, you must first import the certificate. Then you modify the properties of the external Web listener for the Remote Web Workplace publishing rule to use the certificate. You need to do this if you want to configure Remote Web Workplace with a public certificate from a trusted certificate authority. You also need to do this if you use the private certificate authority in Windows EBS but you issue a certificate for a different remote access URL than the one that was originally configured in Windows EBS (for example, if you want to use the URL rww.adventure-works.com instead of remote.adventure-works.com).

noteNote
For more information about how to request and install a certificate from a commercial certificate authority, see “Configuring server certificates for secure Web publishing” at the Microsoft Web site (http://go.microsoft.com/fwlink/?LinkId=137107). To create a domain certificate from the private authority in Windows EBS, use the Create Certificate Wizard in Internet Information Services (IIS) Manager on the Security Server. For more information, see “Create a Domain Server Certificate in IIS 7.0” at the Microsoft Web site (http://go.microsoft.com/fwlink/?LinkId=137111).
noteNote
By default, the external Web listener for Remote Web Workplace is configured to use the certificate that is issued by the private certificate authority in Windows EBS. If you choose to use this private certificate, you must install a root certificate on client computers, which validates secure remote access to Remote Web Workplace. For more information about installing the root certificate on client computers, see Install Root Certificate on a Remote Computer.
noteNote
You must use an account that is in the Domain Admins group to perform this procedure.
