Troubleshooting Autodiscover.Proxy Health Set

 

Applies to: Exchange Server 2013

Topic Last Modified: 2013-05-03

The Autodiscover.Proxy health set monitors the availability of the Autodiscover proxy infrastructure on the Client Access server (CAS). The Autodiscover.Proxy health set is closely related to the following health set:

Troubleshooting ClientAccess.Proxy Health Set

If you receive an alert that specifies that the Autodiscover.Proxy is unhealthy, this indicates an issue that might prevent your users from discovering their mailboxes by using the Exchange Autodiscover process.

The Autodiscover service is monitored by using the following probes and monitors.

 

Probe Health Set Dependencies Associated Monitors

AutoDiscoverProxyTestProbe

Autodiscover.Proxy

Active Directory

AutodiscoverProxyTestMonitor

For more information about probes and monitors, see Server health and performance.

This probe can fail for any of the following common reasons:

  • The application pool that’s hosted on the monitored CAS is not working correctly.

  • The monitoring account credentials are incorrect.

  • The Domain Controllers are not responding.

It's possible that the service recovered after it issued the alert. Therefore, when you receive an alert that specifies that the health set is unhealthy, first verify that the issue still exists. If the issue does exist, perform the appropriate recovery actions outlined in the following sections.

  1. Identify the health set name and the server name in the alert.

  2. The message details provide information about the exact cause of the alert. In most cases, the message details provide sufficient troubleshooting information to identify the root cause. If the message details are not clear, do the following:

    1. Open the Exchange Management Shell, and then run the following command to retrieve the details of the health set that issued the alert:

      Get-ServerHealth <server name> | ?{$_.HealthSetName -eq "<health set name>"}
      

      For example, to retrieve the Autodiscover.Protocol health set details about server1.contoso.com, run the following command:

      Get-ServerHealth server1.contoso.com | ?{$_.HealthSetName -eq "Autodiscover.Protocol"}
      
    2. Review the command output to determine which monitor reported the error. The AlertValue value for the monitor that issued the alert will be Unhealthy.

    3. Rerun the associated probe for the monitor that’s in an unhealthy state. Refer to the table in the Explanation section to find the associated probe. To do this, run the following command:

      Invoke-MonitoringProbe <health set name>\<probe name> -Server <server name> | Format-List
      

      For example, assume that the failing monitor is AutodiscoverSelfTestMonitor. The probe associated with that monitor is AutodiscoverSelfTestProbe. To run that probe on server1.contoso.com, run the following command:

      Invoke-MonitoringProbe Autodiscover.Protocol\AutodiscoverSelfTestProbe -Server server1.contoso.com | Format-List
      
    4. In the command output, review the Result value of the probe. If the value is Succeeded, the issue was a transient error, and it no longer exists. Otherwise, refer to the recovery steps outlined in the following sections.

When you receive an alert from a health set, the email message contains the following information:

  • Name of the CAS that sent the alert

  • Full exception trace of the last error, including diagnostic data and specific HTTP header information

    You can use the information in the full exception trace to help troubleshoot the issue.

  • Time and date when the issue occurred

To troubleshoot this issue, follow these steps:

  1. Review the protocol logs on the CAS. Protocol logs are located in the <exchange server installation directory>\Logging\HttpProxy\<protocol> folder on the CAS.

  2. Create a test user account, and then log on to the CAS by using the test user account. For example, log on by using: https:// <servername>/owa.

  3. Start IIS Manager, and then connect to the server that’s reporting the issue. Verify that the MSExchangeAutodiscoverAppPool is running on CAS.

  4. Click Application Pools, and then recycle the MSExchangeAutoDiscoverAppPool application pool by running the following command from the Shell:

    %SystemRoot%\System32\inetsrv\Appcmd recycle MSExchangeAutoDiscoverAppPool
    
  5. Rerun the associated probe as shown in step 2c in the Verifying the issue still exists section.

  6. If the issue still exists, recycle the IIS service by using the IISReset utility.

  7. Rerun the associated probe as shown in step 2c in the Verifying the issue still exists section.

  8. If the issue still exists, restart the server.

  9. After the server restarts, rerun the associated probe as shown in step 2c in the Verifying the issue still exists section.

  10. If the probe continues to fail, you may need assistance to resolve this issue. Contact a Microsoft Support professional to resolve this issue. To contact a Microsoft Support professional, visit the Exchange Server Solutions Center. In the navigation pane, click Support options and resources and use one of the options listed under Get technical support to contact a Microsoft Support professional. Because your organization may have a specific procedure for directly contacting Microsoft Product Support Services, be sure to review your organization's guidelines first.
