I’m trying to encrypt the Offline files Cache (“%systemroot% \ csc” folder) for all of my laptop users via a GPO in a 2003 domain. Without implementing the Group Policy, I can manually check the “Encrypt offline files to secure data” box, and the files will encrypt. But whenever I attempt to set the policy via Group Policy in Computer Config \ Admin Templates \ Network \ Offline Files \ Encrypt offline files cache = “Enabled”, the “Encrypt offline files to secure data” box on the client greys out, but doesn’t check. I then verify that the files aren’t encrypted by accessing them remotely and by viewing the output of the cipher command.
I’m currently trying to implement this just using a test GPO, where the offline file encryption is the only item configured. I verified that nothing from the default domain or the computer’s local policy are blocking this policy. Also, I’ve tried manually adding registry entries to HKLM \ Software \ Windows \ CurrVer \ NetCache, but that doesn’t work either.
I’m not using Fast User Switching on my XP client. I also don’t have compression enabled on the drive where the offline files live. How can I ensure that all my laptoppers have encrypted offline files without having to visit them door-to-door?
