SYMPTOMS
On a clustered or multiprocessor Microsoft Exchange 2000 Server computer, you experience all the following symptoms:
 * The Exchange 2000 computer stops responding to client requests.
 * The Inetinfo.exe process together with the Store.exe process consume 100 percent 0f CPU time.
 * If you run the Performance tool, you notice that a very high number of context switches per second occur. In this scenario, you experience an average of 75,000 context switches up to a maximum of over 100,000 context switches when you monitor the ContextSwitches/Sec counter for the Thread performance object.



If you fail over the cluster node when you experience these symptoms, the issue is temporarily resolved.
