I have an MP4 file on our Windows 2008R2 fileserver that I want people to be able to view, but not to create copies of. Is there a security permission configuration that would allow this?

This is not possible in Windows. When you grant user "Read" permission, then copying is possible. You can always enable Folders/Files auditing and review log to check who copied data and when to track this issue.

To my knowledge, there can be no permissions that would permit a user from viewing the file and at the same time prevent that user from copying the file.

This is exactly what DRM is for. Whether you can effectively wrap MP4 into a DRM scheme, I have no idea - now you have the terminology to allow you to try yourself! Remember how effective most DRM schemes are, though.
