[erlang-questions] ODBC driver

[Jose Enrique Benitez Jimenez]

Hi,
 
I want to connect to an SQL database, I receive the follow error
 
7> odbc:start().                    
ok
8> odbc:connect("DNS:localhost",[]).
{error,"No SQL-driver information available. Connection to database failed."}

 
SQL server 2000 is already intalled, Do I need the ODBC driver or SQL server 2000 have it ?, in the first case, how can i get it??
(I'm using Windows XP)
 
Thanks.
