Vista - Offline Files and Redirected Folder

Hi,

On our network My Docs, My Pictures, and My Music are all redirected to
different locations. Our workstations have offline files disabled.

However on our laptops/tablets with offline file enabled, My Pictures and My
Music are cached along side My Docs. I understand this is the default
behaviour as they are redirected folders, however I can't seem to stop it.

Uses don't have the option to remove the folders manually - its greyed out.
I've tried specifying the UNC paths as not to be available offline in group
policy - that doesn't appear to work (it states XP only on that option - is
that an oversight or does it really not apply to Vista?)

My Music and Pictures really can't sync as they are 200+GB in size.

Any ideas?

Thanks Daniel
