Every computer on which you install Office Communications Server
2007 R2 server roles must be assigned a certificate. To assign a
certificate, follow the instructions in
Request a
Certificate (Command Line). Note that if your configuration has
multiple Front End Servers, the same certificate can be used for
each of those servers. If the certificate was created with the
/Exportableparameter set to True, the certificate can be
exported then imported on a different computer and assigned to the
server. Server roles other than the Front End Server require
certificates with a subject name that matches the FQDN of the
computer on which the server role is installed.
