This section describes the new server configuration options that have been added Communicator Web Access (2007 R2 release).

 In This Section

• Redirecting Users of Previous Releases
  Although users homed on previous versions of the software cannot log on to a Communicator Web Access (2007 R2 release) site, you can configure that site to automatically redirect those users to a server running a previous version of Communicator Web Access.
  
• Configuring a Next Hop Server for Anonymous Users
  The next hop server makes it possible for "anonymous users" (that is, users who do not have an account in your Active Directory or the Active Directory of a federated partner) to be invited to take part in conferences and desktop sharing sessions.
  
• Configuring Desktop Sharing
  With desktop sharing, users are able to see everything that is happening on another person's computer. In addition, these users can even be allowed to take control of that computer, using their own mouse and keyboard to do such things as enter data or run applications.
  
• Configuring Audio Conferencing for Communicator Web Access
  Communicator Web Access (2007 R2 release) enables you to add audio (that is, using standard telephones and cell phones) to any instant messaging (IM) session or desktop sharing session.
  
• Configuring Distribution Group Support for Communicator Web Access
  Communicator Web Access (2007 R2 release) not only enables you to use an Active Directory distribution group as a contact, but it also lets you expand the group membership. In turn, that lets you send separate messages to or view the presence of all the members of that group.
