Event Viewer

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.

Event Viewer records events for Office Communications Server events on a server that is running Office Communications Server 2007 R2. When enabled in Office Communicator, Event Viewer also maintains logs about program, security, and system events on your client computer. When logging is enabled on a client, Communicator writes the following types of errors to the Windows system event log, along with detailed troubleshooting information:

  • Errors that prevent a user from signing in to the server, such as host or domain name errors, or an invalid certificate.

  • Diagnostic messages returned by the server, such as version check failures, problems with sign-in credentials, or errors generated in response to a SIP INVITE message from the client.

  • Windows event trace log (ETL) files, which may also be generated on your computer in the <username>/Tracing folder, enable administrators and Microsoft support technicians troubleshoot problems. For details, contact your Microsoft Customer Service and Support representative.

To enable Event Viewer in Communicator, on the Tools menu, click Options. On the General tab, under Logging, select the Turn on Windows Event logging for Communicator check box.
