Assuming you have defined a system (or possibly user) DSN "teracon" via ODBC control panel, and want to use that to connect: your connection string should specify "DSN=teracon;..."

Provider= should be allowed to default to MSDASQL for use of ODBC via ADO, Driver= is not used with DSN, Server= is not used by the Teradata driver. If you didn't want to set up a DSN, you could use "Driver={Teradata};DBCName=<hostname or IP address>;..." but you'd need to append any relevant option settings (that otherwise would be set via the ODBC DSN configuration dialog) to the connection string - see the manual for Terdata ODBC Driver.

However, if you are using ADO, why not install and use the Teradata OLEDB Provider (Provider=TDOLEDB) instead?
