pass through query not working correctly via VBA in Access

I am trying to set a passthrough query to run via VBA the code grabs the product ID and puts that in the SQL for the passthrough it them is suppose to run a append query that runs off of the pass though to append the records  into a table in access.  If I set this up in access it runs fine, but when I try to run it via the VBA code I get an error when I get to the append query "0100 get samples"
The error says Cannot find file c:\Documents and settings\amcfall\My Documents\siebel.mbd.  

Something happens to the passthrough when the code exectues, the SQL looks ok but the connection part doesn't, I first have to reset the query type to passthrough and then reset the ODBC connection information in the property sheet, so I assume what is happening is that the code is not correct to set up the passthrough in the VBA...

      Do Until rstTest.EOF
      sProdId = rstTest!ROW_ID
      CurrentDb.QueryDefs.Delete "qry_samples"
     Set crsePassThru = CurrentDb.CreateQueryDef("qry_samples")
        With crsePassThru
          .ReturnsRecords = True
       
            sSQL = "select sa.pr_prdint_id, sa.target_per_id, sa.target_ou_id, co.email_addr" _
                                        & " from SIEBEL.s_evt_act sa," _
                                        & " SIEBEL.s_contact co" _
                                        & " where sa.target_per_id = co.row_id" _
                                        & " and pr_prdint_id = '" & sProdId & "'"
