Interesting. I upgraded my SEP Management console from 14.2 RU2 MP1 to 14.3 RU2 three days ago, and got the message that it succeeded, and was able to log into the Manager console. However, I get "Query Failed" messages when I click on the details for Endpoint Status in the Home tab, and when clicking the Monitors tab. (The Endpoint Status square does not show any data like it should either, and Reports didn't work.) Hitting refresh brings up the 'File or Directory Was Not Found', same as the screen shot from the Original Poster.
In my Apache reporting.log, there were several Microsoft OLE DB Provider for ODBC Drivers errors such asEXCEPTION: com_exception: <b>Source:</b> Microsoft OLE DB Provider for ODBC Drivers<br/><b>Description:</b> [Microsoft][ODBC Driver 13 for SQL Server][SQL Server]Invalid column name 'URL_ONOFF'
EXCEPTION: com_exception: <b>Source:</b> Microsoft OLE DB Provider for ODBC Drivers<br/><b>Description:</b> [Microsoft][ODBC Driver 13 for SQL Server][SQL Server]Invalid column name 'URL_ONOFF'
Invalid column name 'PRODUCTVERSIONFROM'
Can you please also create a support KB. It's obvious now that this issue affects multiple customers. We've seen it in two separate environments and have stopped all 14.3 RU2 upgrades for our customers.
The error we are focusing on currently is -
[Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Cannot resolve the collation conflict between "SQL_Latin1_General_CP1_CI_AS" and "Latin1_General_CI_AS" in the equal to operation. in E:\Program Files (x86)\Symantec\Symantec Endpoint Protection Manager\Php\Include\Common\ado.php:587
The symptom is SEPM homepage now loading.
It appears this thread has multiple issues being reported so I wanted to be clear regarding the issue we are investigating in ESCRT-7187
As we have more information a KB will be created.
In Symantec days we could subscribe to a whitepaper to receive email updates, have you contemplated doing it again for critical situations like this ...?
