Is there any way (in DNN 7) to have some roles that require the Admin to approve before a page is accessed and other roles that don't.
When a user signs up I want them to be given two roles (this will be done by Dynamic Registration module), one role will be automatically assigned and automatically approved giving them access to pages viewable by that role BUT the other role will also be automatically assigned (based on a Dynamic Registration field input) but the admin MUST give approval before the user is able to access additional pages. They must be able to login as the first role will be active but how do I go about only letting them view the extra pages once I manually approve them?
Is that possible without additional modules? If so, how?
Thank you.

Try using a third role that is initially denied access to those special pages. The administrator's "approval" would be to remove that role, thereby giving them access.
