I just want to double check with you that you have done everything you need to do. So here is an example from my own code that works:
oconn.ConnectionTimeout = 0
oconn.CommandTimeout = 0
oconn.Open "Driver={SQL Server};Server=Hal2000;Database=Europa;Uid=sa; Pwd= :P ;timeout=0;"
One final thing do you need to set up an ODBC connection on the computer, and if you do have you set this up?
You always pass failure on the way to success.
