SqlServer's DTS Job Schedule(編號:515)

在SQL Server7.0上產生之DTS Package可直接執行,但以DTS產生之JOB卻會產生下述Error Message:Error = -2147008507 (80074005)   Error string: 無法指出的錯誤     Error source: Microsoft Data Transformation Services (DTS) Package   Help file: sqldts.hlp   Help context: 1100   Error Detail Records:   Error: -2147008507 (80074005); Provider Error: 0 (0)   Error string: 無法指出的錯誤     Error source: Microsoft Data Transformation Services (DTS) Package   Help file: sqldts.hlp   Help context: 1100     Error: -2147467259 (80004005); Provider Error: 0 (0)   Error string: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified   Error source: Microsoft OLE DB Provider for ODBC Dri.
請協助解決,謝謝!!!!!!!
