Summary

This Knowledgebase article provides information about error messages logged in the Application logs each time Neverfail Application Module Monitor Service starts in an Exchange 2007 server deployment that does not host the Exchange mailbox role.


More Information

Symptoms

In an Exchange 2007 server deployment that does not host the Exchange mailbox role.

Windows Application logs will contain the following errors each time the Neverfail Application Module Monitor Service starts up:

Cannot find RPCRequests (0x80041010) in Windows Management Instrumentation.

Failed to obtain a value for attribute RPC Requests, Instance:

Win32_PerfRawData_MSExchangeIS_MSExchangeIS=@ from Windows Management Instrumentation

Unable to query attribute RPC Requests, Instance:

Win32_PerfRawData_MSExchangeIS_MSExchangeIS=@ (0xFFFFFFFF).

Ignoring this attribute until Neverfail Monitor Service is restarted or reconfigured. This error indicates that the attribute is not available from WMI. To verify the existence of this attribute, use perfmon /wmi. This error may indicate that an application or its management interface is not correctly installed. It could also indicate that the WMI service is not responding, in which case the WMI service and the Neverfail Monitor service should be restarted.

Cause

These error messages are logged as a result of the server role (Edge Transport server), and because it does not host the mailstore role. The performance counters will not be present in WMI and cannot be monitored.

These errors will be present on any server that runs Neverfail for Exchange and does not
host the mailstore.

Resolution

These error / warning messages can be safely ignored. At present, there is no
way to suppress this message when the Application Module Monitor Service starts
up. Further messages will not be logged until the service restarts.


Applies To

Neverfail for Exchange V5.1 or Later
