Does this actually fail before you open the connection, just when 
creating a ADODB connection object?!. It shouldn't know anything about 
the driver at that point, cause you haven't told it what you want to 
connect to.

Have you commented stuff out until it ceases to fail?

I'd suspect a permission problem,...either IIS's account doesn't have 
permission to someplace/something on the system,... or PostgreSQL is 
rejecting the connection attempts from 127.0.0.1 for the account. But 
lets not jump to conclusions. The ODBC driver also might bot be "well 
uninstalled/reinstalled", but given what you've already done I doubt it.

Have you checked the IIS log (%win_system32%\logfiles\w3svc?)
Is PostgreSQL set to log failed/successful connections?

I don't quite understand what it is trying to do when it is failing.
Is it actually failing on the Connection open. Have you tried a DSN? 
That could rule-in/out a connection string problem.
