I’m curious to know what industry you work in, what version of SharePoint you are using, and how many users are in your network?
I work in higher education. Our internet is on SP 2010 and we will be launching our Intranet in August using SP 2013. We have 38,000 faculty, staff and students.
A single farm with a web application for each school. We can only launch with Intranet access to faculty, staff, and student workers. No students until we get the licensing issues resolved. Which brought up the question of how to restrict students but not student workers. Please offer your suggestions at my discussion here: http://sharepoint-community.net/forum/topics/differentiating-students-in-the-ad
