Issue/Introduction

Downloading files from quarantine in the Endpoint Protection Manager results in a failure and a blank page being displayed instead of the download starting.

access.log shows a 500 error:

"POST /Reporting/command/runcommand.php HTTP/1.1" 500 

Reporting.log shows a failure calling the function "is_sqlsrv_enabled".

PHP Fatal error:  Uncaught Error: Call to undefined function is_sqlsrv_enabled() in C:\Program Files (x86)\Symantec\Symantec Endpoint Protection Manager\Php\Include\Common\connectdb.php:131

Environment

Cause

Connectdb.php may have been locked during the SEPM upgrade and an older version is present on the system.  The call to is_sqlsrv_enabled was removed starting with 14.3 RU2.

Resolution

File should be replaced with a known good copy and SEPM services restarted.
