How to Set Deny Users to Move one Folder to Another but Allow them full permission on the folder they are assigned

Hi,

We have a network drive called Drive P (for example) and under Drive P are Folder A and Folder B. 

SCENARIO

1.  Security Group Folder A gives full rights to Folder A (all subfolders and files).  Security Folder B gives full rights to Folder B (all subfolders and files).

2.  If John has memberships to both Security Folder A and Security Folder B, John can (accidentally) move the entire Folder B to Folder A.  When John attempts to undo by moving back Folder B out of Folder A (putting it back to the root of Drive P) he gets access is denied.  He is not allowed to move back to the root of the drive, which is perfectly OK.

3.  What NEEDS TO HAPPEN is not allow John to move Folder B to Folder A in the first place and vice versa.  However,WE NEED John to own everything (files and subfolders), rename, delete, add, create inside Folder A and B but not allow him to move one folder to another.

How do we set this up? We are using Windows 2008.

Thanks!
