Hi, I'm getting that nasty error msg, although you could test the oledb connection in the sybase data source configuration, so I think the error is relevant to SSIS not the sybase. [IM002] [Native Code: 30136] [ASEOLEDB]Data source not found and no default driver specified I'm using windows 7, 64BIT, ASE Version 15.5 , i've the same setup and configuratio working on a vista 64 bit, but found other posts online about windows 7 and the driver is working on it. any thoughts?MCITP - BI 2008 http://asqlb.blogspot.com/
