When accessing the page "DASuccess.asp" by entering an http address in Internet Explorer, the page is displayed without errors.

Issue / Cause

Directory Assistant uses the "session" feature in Internet Explorer in order to keep track of information about the changes a user is making throughout the request process.  If Internet Information Server has been configured to not allow session information, the web pages will not function properly.
