The troubleshooting tools are simple to access and use, yet they provide in-depth and useful
diagnostic information.
Diagnostics
OCS 2007 provides a ton of great features to enable end-users to be more effi cient in their
jobs. It is important for OCS to have good diagnostic information to help keep your OCS
deployment happy and healthy. Good diagnostics allow you to proactively fi nd issues and
prevent downtime as well as restore services quickly when there is an outage. This section
covers some of the great diagnostics features available in OCS 2007.
Diagnostics Headers
Microsoft has provided what is referred to as MS-Diagnostics headers in OCS 2007. MS-Diagnostics
headers are used to allow servers to pass detailed diagnostics and suggested resolutions to client
computers. MS-Diagnostics headers are included in most Session Initiation Protocol (SIP)
Response errors. Diagnostics headers typically include the error source, components, reason,
and any other details relevant to the error (see Figure 12.10). Because diagnostics headers are
included in the SIP Response instead of the SIP Request, they are sent by the server to the
client. The client then processes the headers to display the information in the client event log.
NOTE
For security reasons, MS-Diagnostics headers are not passed to federated
partners. MS-Diagnostics headers often contain detailed information regarding
your OCS infrastructure.

Runtime Server Diagnostics
Along with MS-Diagnostics headers, OCS provides runtime server diagnostics to assist with
troubleshooting server problems.
