Windows2003/HELM ODBC/PHP Connection Error

Using HELM on windows 2003.

One of our client is using PHP and storing the data via ODBC DSN.

He has created a ODBS DSN under helm and the connection strings on php pages, but the problem we are having is everytime they try to store the data (after a user has submitted a form) it just shows a blank page and nothing gets stored in the DB?

Are there any possible authentication settings for ODBC? as in default username/password? or do we specify any UN/PW somewhere? or could it be some other settings on the server?

At the moment this is what they are using:

odbc_connect('db_name','','')"

What would be the standard procedure to get this done properly?

TIA.
