OK this is a goodun.
Our old admin server died last week. We've got the new one in place and all data restored from backup.
Thing is, one user has somehow encrypted a few of her files and folders.
Reading on the MS site we cannot decrypt because we weren't granted access at time of encryption.
I've tried creating her account with same name to see if it would let her do it, but no.
Is there any way of decrypting them at all? We don't have the old server any more so if there were settings on there that needed to be changed, we're :censored: basically.
If decrypting was that easy, they'd be no point encrypting. I think you may need to look for a third party utility to unlock the files. I have never tried in practice, so I don't know how difficult it is to unlock or how high an encryption level is used.
I think it is possible. The users private EFS encryption/decryption keys are held in the registry. As Admin, you can get hold of those, thus you should be able to decrypt the files/folders.
I haven't found a tool that's free that implements this though.
Googling for 'recover EFS' turns up a few promising looking hits. This one (encrypted file system recovery) had some tech info if you are wanting to DIY.
