I'm using DSN-less connections to my SQL Server in an Access database. However, whenever I try to write a "Pass-Through" query and run it, a dialog box pops up asking for the DSN.
In SQL view, choose properties after you have selected passthrough query and insert an ODBC connect string. For example:
ODBC;DRIVER=SQL Server;SERVER=Server\Instance;Trusted_Connection=Yes;DATABASE=Test
