Resolved issues

The customer saw the following error: “The process was terminated due to an unhandled exception, System.OutOfMemoryException.” The issue was caused by processor and memory limitations (set by default) in a large scale environment. A new retry method is implemented to ensure the test engine can handle unexpected situations.

After upgrading to Exchange 2016 CU 4, the Exchange Modern Message Delivery Health Test failed with the following error: “Organization exit status within timeout - Failed to exit. The message did not exit the Exchange organization within the timeout”. The cause was a new event ID “SENDEXTERNAL” that was introduced in the message tracking log file in CU 4. The new event ID is now supported.

593819

For a Skype for Business/Lync environment, if a DNS Alias record is configured for a front-end pool or standard edition server rather than a Host A record, UC Diagnostics will fail to discover and run the synthetic transaction health tests with that pool or server. This issue is only found on 32-bit and 64-bit systems of Windows 2008. Newer operating systems do not have this issue.

325647

In Skype for Business or Lync Discovery, the display name of PstnGateway only shows the numbers/characters before the first dot. There is a problem when PstnGateway name is an IP address.

354306

Upgrading from version 8.2 or later

As of UC Diagnostics 8.3, Exchange 2000 and Exchange 2003 are not supported. If you are upgrading from UC Diagnostics 8.2, use the Force Discovery Now option to repopulate your topology view. If you are upgrading from 8.3, use this option to ensure Exchange version service pack and CU (cumulative update) information is shown for Exchange servers.

If the BlackBerry Server Health Test runs on a standby BlackBerry server in a high availability configuration, the test results show errors for BlackBerry services that are not running. However, these services are not required to run in the standby server and no error exists.

Workaround: Perform the BlackBerry server health test on the primary BlackBerry server only, or run a separate BlackBerry server health test on the standby BlackBerry server with the affected service counters set to 'informational'.

If you are installing Exchange 2013 and have upgraded to the newest version of MAPI & CDO (version 6.5.8320.0) to support RPC over HTTP) in a mixed environment, some health tests may not run properly. ESM and MAPI & CDO might not work together.

UC Diagnostics 8.4.1 has been rebranded to the Quest company name and the installation path now is Quest. After you upgrade to 8.4.1, the Save As Template and Save As (Drilldown/AlarmLog) dialogs might still point to the previous installation path since Windows saved the path in the registry.

Workaround

You must manually redirect and save to the new default Quest path such as "%current_user%\AppData\Roaming\Quest\Shared\Templates".

If there is no Reverse Lookup Pointer (PTR) created for the target Lync 2013 Server in a different domain and users connect the server with its NetBIOS name, the Lync 2013 plug-in of the diagnostic console is unable to get values for some components.

In Data Recorder Mode, if you connect to a Lync 2013 or Skype for Business 2015 Server with the NetBIOS name (such as wm-skp-st), the home page does not display properly. Some components are greyed out in the Diagnostics Console Play Back Mode.

Workaround

Use the server FQDN instead of the NetBIOS name when you connect in Data Recorder Mode.
