Unexpected Server Error when logging into Symantec Endpoint Protection Manager console.
The Home, Monitors, and Reports tab may be blank.
Unexpected Server Error
This may happen if the Symantec Endpoint Protection Manager is using a SQL database, the SQL installation has only one named instance in it, and the Endpoint Protection Manager was configured using the default values of SQL server_name and port, rather than server_name\instance_name and port.
Re-run the Symantec Endpoint Protection Manager Server Configuration Wizard, and specify server_name\instance_name and port when configuring the SQL database connection.
