  • Hi Timothy,

    Please run Get-ServerComponentstate -Identity servername and check the results
    All the components should be Active
    If you find any components to be inactive then we need to activate them
    Set-ServerComponentState -Identity servername -Component Componentname -Requester HealthAPI -State Active

  • All components show active.

    I'm not sure if this is related, but also after the CU6 install when opening an instance of Server Manager that has the exchange server host added as a managed server the initial load of event log data from the Application log fails.  Sometimes I have been able to load it by simply refreshing the node.  However there has been some cases where the only way I could get all aspects of the server to load is to clear the Application log.

    Additionally, every so often I am getting alerts in SCOM for "Maintenance workitem "WindowsServerRoleEndpointMaintenance" (ID: 4) has timed out." from the Exchange Health Set monitor.

  • I have removed and reloaded all exchange performance counters from %EXCHANGEINSTALLPATH%\Setup\Perf and I have also attempted to rebuild all performance counters with lodctr /R but neither resolved the issue.

  • Hi,

    Here is a related KB for your reference, please check the suggestions in this article to see if it works.

    http://support.microsoft.com/kb/2870416

    And please check the Exchange setup log to see if there is any related error message.

  • I have already run this script to reload the performance counters.  There are no errors in the setup log except for the ones about not finding the definition files in the \Perf\AMD64 directory (which loading them manually out of the \Perf directory should have resolved)

  • I have the exact same issue with the exact same counters.

    Actually did all you did (counters reload, rebuild etc.). Im thinking it might be a certificate somewhere that isn't right. Cant find anything else really. If you ever find a solution, that would be good.

    At the moment we are waiting for CU7 to see if the patch fix it.

  • It seems the issue was resolved in CU8.

    I used method 1, but it did not help me.

    Method 2:

    Any idea ?

  • + 1. CU8 on 2012R2 - CAS role. Same issue on repeat.

  • +1 Another 2013 CU8 on 2012 R2 issue identical to above

  • Actually, I may be on to something now.

    Can someone else having the issue run the below command:

    New-PerfCounters -DefinitionFileName "C:\Program Files\Microsoft\Exchange Server\V15\Setup\Perf\InfoWorkerMultiMailboxSearchPerformanceCounters.xml"

    if it fails, that could be the problem. Mine was failing and it is due to leading and trailing spaces in the <name> fields in that XML.

    I have removed those spaces and ran it again and it went through OK - so now I wait to see if the problem is fixed.

    Will update.

  • Hi James,

    I have tried your solution, unfortunately with no positive results. Indeed the command initially failed and cleaning the leading spaces for a few <name> tags subsequently made the command run. But the following errors are still generated every 15 minutes:

  • Same issue here.  CU8.  Reinstalled all counters, but continue to get this 106 'ad-powershell-defaultdomain' counter error.  Sure would be nice to get it out of the logs!
    Friday, June 26, 2015 4:16 PM
  • I'm running CU9 here and still have this same issues since CU5.  This error throws off our heath status in Solar Winds and it would be nice to get this resolved.

    Monday, August 24, 2015 4:32 PM
  • Yeah, another +1 on CU8 here.

    Tuesday, September 15, 2015 1:46 PM
  • Same problem here With CU9, have had it since CU6 at least.
    Tuesday, September 15, 2015 2:57 PM
  • I've run the script suggested below and the errors are still happening.

    https://support.microsoft.com/en-us/kb/2870416

    Tuesday, October 13, 2015 11:43 AM
  • We just stood up a new Exchange 2013 CU7 environment and, after reloading all of the performance counters per Microsoft's recommendation, we are still seeing event id 106 from MSExchange Common pertaining to "Instance 'ad-powershell-defaultdomain' already exists with a lifetime of Process."
    Friday, October 23, 2015 11:04 AM
  • Hi All,

    Any luck getting this error fixed?

    Thanks,

    David

    Tuesday, January 5, 2016 7:35 PM
  • I fount the counter in question (Time in Resource per second, category name is MSExchange Activity Context Resources) defined in ActivityContextPerformanceCounters.xml. I reloaded that using the instructions KB 2870416 with no luck, still seeing this error spam my logs. Running CU9. This started happening a few days ago for me, so I have not had the chance to see if a reboot would clear it. Anyone else try that? Does anyone know if this has been reported as a bug?
    Thursday, February 4, 2016 10:19 PM
  • +1 there
    Tuesday, February 9, 2016 3:11 PM
  • Same issue here. Exchange 2013 CU9 on windows server 2012 R2. 4 multi-role servers with CAS+MBX and all 4 servers showing same error.
    Monday, February 29, 2016 11:30 AM
  • Hi,

    any news about this issue, I have the same alerts in my Exchange 2013 and 2016 servers.

    Thanks!

    Tuesday, March 22, 2016 12:48 PM
  • Same here, Exchange 2013 CU12,  error started with CU7 and been around since. Fresh install of Exchange 2016  CU1 on Server 2012 R2 has the same error.
    Tuesday, March 29, 2016 12:36 PM
  • Same here with Exchange 2016 on Windows 2012 R2 (currently with CU1 which was released some days ago).

    Did anybody created a ticket for Microsoft for that?

    Thursday, May 12, 2016 7:47 AM
  • Same issue with CU12 running on Windows 2012 R2.  Has anyone opened a ticket on this with MS? 

    Monday, May 23, 2016 2:15 PM
  • Getting same errors in Exchange 2013 CU13. Anybody found solution on this issue.
    Thursday, August 11, 2016 11:08 AM
  • In my case

    AdminDisplayVersion : Version 15.0 (Build 1178.4) CU12

    I can see:

    Server     State         Name                                 TargetResource HealthSetName AlertValue ServerComponent
    ------     -----         ----                                 -------------- ------------- ---------- ---------------

    ----                        -------- -------------- --------
    HealthManagerHeartbeatProbe    Probe                Monitoring\HealthManagerHeartbeatProbe

    Then I run

    [PS] C:\>Invoke-MonitoringProbe -Identity Monitoring\HealthManagerHeartbeatProbe -Server (hostname)

    MonitorIdentity                          StartTime       EndTime         Result               Error                Exception            PoisonedCount

    Monitoring\HealthManagerHeartbeatProbe   11/16/2016 1... 11/16/2016 1... Failed               Failed by design.    System.Exception:... 0

    Hey!? It is "Failed by design".!!!

    OK.!

    Lets add an override:

    $ExVersion = Get-Command ExSetup.exe | ForEach-Object {$_.FileVersionInfo.ProductVersion}
    Add-GlobalMonitoringOverride -Identity "Monitoring\HealthManagerHeartbeatProbe" -PropertyName Enabled -PropertyValue 0 -ApplyVersion $ExVersion -ItemType Probe

    Add-GlobalMonitoringOverride -Identity "HubTransport\MaintenanceTimeoutMonitor.Monitoring" -PropertyName Enabled -PropertyValue 0 -ApplyVersion $ExVersion -ItemType Monitor

    Restart-Service MSExchangeHM -Verbose

    I hope that can help to hide the issue.

  • Same issue here, Exchange 2013 CU13. Did anyone tried the above solution or some other things to do?

  • Hi,

    Still same error in the application log every 15 minutes (Exchange 2013 CU 19 on Windows Server 2012 R2).

    Can someone from Microsoft confirm this is a bug? And if it's planned to be fixed?

    Regards.
