MSExhange Configuration Core Errors

Question

Hello all,

I've looked just about everywhere and have done a lot of tasks trying to correct this error, but I feel like I'm going in the wrong direction. It's an exchange 2013 Environment. There errors are all over the event log and, because of these, I am unable to login to the ECP. I have rebuilt the counters using lodctr /r but these errors persist. Any insight would be great. I will post the error details below. The General tab of the log states

"The description for Event ID 1 from source MSExchangeConfiguration Core cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer."

The details are below

Hi @Rob Cochran ，

Before going further, would you please tell us what error do you see when trying to access ECP?

I have rebuilt the counters using lodctr /r but these errors persist.

After running the command lodctr /R in elevated command prompt, have you already run an IIS reset and check how it goes?

If the error persists, please try manually loading the TenantMonitoring counter which is mentioned in the event logs:

1.Close Performance Monitor, and then stop any other monitoring services that might be trying to use the missing counters.
2.Run Exchange Management Shell as Administrator, type the following command, and then press Enter:

Add-Pssnapin Microsoft.Exchange.Management.PowerShell.Setup  

3.Run New-PerfCounters to add the performance counter:

New-perfcounters –definitionfilename “C:\Program Files\Microsoft\Exchange Server\V15\Setup\Perf\MSExchangeTenantMonitoringPerformanceCounters.xml"  

4.Reboot the Exchange server for the change to take effect and check the result.
