2.5.1.4 Diagnosis and Troubleshooting

When an IT administrator is alerted that a failure has occurred or is soon to occur, it is not always possible to directly diagnose the computer in question. Instead, the computer is often diagnosed remotely. The remedy might be carried out programmatically based on data collected through monitoring, or the IT administrator might be alerted to the problem and explicitly connect to the computer and diagnose the problem. Because some of the more severe failures can leave a computer's operating system in a nonresponsive state, it is often necessary to carry out troubleshooting and diagnostics by directly communicating with a computer's hardware.

Diagnosis is a one-to-one operation where the WM application or IT administrator queries and sets the state of CIM objects on a single host to diagnose and correct problems.

The following diagram shows the diagnosis and troubleshooting interactions between a WM client, WM server, and authentication services.
