shared folder can be seen by network uers, have anabled ABE

HI,

I have a number of shared folders i.e. sales, i only want the sales team to be able to see this folder and not others.  I have enabled ABE and given access to the sales team only.  However all users are still able to see the folder but cannot access it.

What am i doing wrong.  We are using 2008 R2.

Thanks

Mo
