Hi Dwight,

You may use the command "cipher" to script or command line efs enc/dec
operations. To be able to enc/dec files stored on remote servers (ie. Trough
shares) you must trust the server for delegation and thus let the server
impersonate your credentials.

I'm not sure if you can share encrypted files with other users beside the
legitimate certificate owner and the recovery agent user. Let me know your
findings..

Cheers,

Ok, heres the situation.  I already went thru the process of setting up efs
on a 2003 remote server and can access the files.  What I want to know is if
it is possible to use the command line to encrypt, and then give access to
the shared file.  I know you use cipher to encrypt/decrypt, but is there a
way to add an additional user to the access list of the shared encrypted
file.
