I am using a system DSN to connect to an informix server. I am using IBM informix client SDK 2.81. My DSN is working fine and giving me no error as there is a test and connect button from which one can check and verify the connection. But when i try to check it with DB ping utility, DSN is giving me this error.Can any body help me to find what the problem is

4:14:22 PM : SQLAllocEnv Successful
4:14:22 PM : SQLAllocConnect Successful
4:14:29 PM : There was an error within SQLConnect!
4:14:29 PM : SQLState = 37000
4:14:29 PM : Native Error = -11060
4:14:29 PM : Error Message = [Informix][Informix ODBC Driver]General error.

Thanks .
