ODBC/IIS/PsotgreSQL

I've inherited a Web based application that was developed using
VisualBASIC, IIS, and SQL Server 6.5 ... which for some reason or other
decided to stop working.  (Before I got it.)  I'm pretty sure the issue is
with SQL Server and authentication but my attempts to fix it have not been
successful.  So I got a 'very clever idea'.  Since the application uses
ODBC (and ADO) I should be able to just set up a PostgreSQL database and
point the ODBC driver at it and let MS, IIS, VisualBASIC, and friends do
their own thing.
  The problem is I can't seem to get things set up correctly.  I am still
researching but was hoping someone might have their own quick-and-dirty
list of directions.  Heck I'd go for a URL even ;-)


TIA,
Rod
