Doug's problem was the use of 32 bit ODBC drivers on x64 servers, right? He found out that 32-bit ODBC drivers do not appear in the ODBC Data Source Administrator. He can use %SYSTEMROOT%\SysWOW64\odbcad32.exe instead of the default program in system32.

This will show all installed 32-bit ODBC drivers. At this point he can use his DSN as he would with any other system.
