Installing Communicator by using Group Policy
Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
When you use Group Policy Software Installation to deploy Communicator in your organization, you should assign the software installation to the Computer Configuration container instead of the User Configuration container.
Publishing from User Configuration results in a per-user installation. However, some Communicator installation files require a per-machine installation, so they will not install. An initialization error will occur the first time that a user runs Communicator.
For more information, see the Microsoft Knowledge Base article 947379, “Error message when you try to start Communicator 2007: The application failed to initialize properly (0xc0150002),” at https://go.microsoft.com/fwlink/?linkid=147165.
