One of the most useful features in Microsoft Office InfoPath 2007 is the ability to publish a form to a document library on a server that is running Microsoft Windows SharePoint Services. By default, forms published to SharePoint document libraries are restricted from accessing system resources and are not allowed to use any software components that are not marked as safe for scripting. Such forms are said to be sandboxed; when a user fills it out, the form is placed in a local cache and denied access to system resources. This type of form inherits its permissions from the domain in which it is opened. You can avoid these limitations by creating a fully trusted form.
