new EFS assistant tool for better management of GP-based EFS
I thought this was pretty cool: http://blogs.technet.com/billcan/archive/2007/03/10/beta-version-of-tool-for-enforcing-efs-encryption-is-shipping-next-week.aspx
Essentially a better tool for enforcing EFS encryption for your mobile users. EFS is Encrypted File System, which essentially encrypts business critical files to prevent against unauthorized access should the mobile device find itself lost or in the hands of evil-doers and competitors.
