Vista folders asking permision

Hello all,

I recently installed the Windows 7 RC x64 in a dual boot configuration along side my existing Vista x64 installation. I set up 7's libraries to view my video and music directories that are on a common shared hard drive, but now when i boot back into Vista, it ask me to provide administrator privileges to access those folders. Does anyone know how to keep this from happening or how to remove this?

Thanks in advance
