How to prevent Logon Dialog box from popping up

I am using SSIS, Attunity and TPT to access Teradata.

But a dialog box pops up at logon , it needs a simple ENTER and then it goes away.  This needs to be stopped , how?

I think there is a global variable somewhere but can't seem to find it.

Thanks
