I have a folder on Windows Vista Business that is shared. When I try to encrypt the folder (apply the Encrypted attribute), I get an error message:

An error occurred applying attributes to the file


The process cannot access the file because it is being used by another process.

How do I encrypt the shared file. Note: There will be only one other computer accessing the file, and it will connect with local user credentials from the computer that is doing the sharing.

I would unshare the folder, encrypt it, then reshare it. However, seems odd to share an encrypted folder. – zackrspv Jan 31 '12 at 20:37
@zackrspv: Two people in accounting need to share some files. Encrypted so that, if a computer is stolen, a third-party cannot read the files without an account password. – Eric J. Jan 31 '12 at 22:46
Well, give it a shot; stop sharing it first, then reboot, then encrypt it, then share it again. Reboot isn't necessary, but I often like the system to clear itself out. – zackrspv Jan 31 '12 at 23:44
