Software Deployment

I need to package a script that will install on remote pc's an system dsn. I can get most of the info I need using the wise script editor and using the get odbc data source and use import. (using SQL driver)The issue is that during the manual config of the dsn there is a configuration option "Connect to SQL server to obtain default settings for the additional configuration options. This is checked by default. I need it unchecked. Unable to find it in the reqistry. Anyone know how I can uncheck it?
