Report Server Windows Service (MSSQLServer) 107
The SQL Server Report Server service cannot connect to the report server database. This error occurs during a service restart if a connection to the report server database cannot be established. Conditions under which this error occurs include the following:
SQL Server Database Engine service is not running when the Report Server service starts.
The connection to the Database Engine service fails because remote connections or the TCP/IP protocol is not enabled.
The report server database is not configured correctly.
The service account is not configured correctly, or the account no longer has permissions on the report server database. This can occur if you do not use the Reporting Services Configuration tool to set up the account or the report server database.
