Re: EFS Recovery Agent

Thanks for all the feed back guys.
I managed to resolve the problem.
I was encrypting the files on a WinXP SP1 workstation, and trying to decrypt
on our W2K Adv Server.
The following KB Article helped resolve the problem, by setting XP to
encrypt data using the DESX algorithm (instead of the default AES_256
Algorithm which is understood by XP SP1 or later) I was able to remove the
encryption on the encrypted files using a RA.
Thanks once again!
