    I have a problem decrypting files that were decrypted in
    XP Pro using the properties dialog box. I have searched
    the KB and cannot find a solution except for Win2000
    systems (264064). I followed the instructions and it did
    NOT work

    I have found the cert for "Encrpting File System" in IE
    Certificates tab. EVERYTHING is checked (except Client
    Authentication and Secure Email)

    I believe I'm the owner of the files (not certain how to
    verify this)

    I've searched hi and low for an answer and still can't
    decrpyt these files.

    HELP!

    TIA
    MM

  2. If you reset your password in Computer Management instead of using
    CRT-ALT-DELETE [you could try changing it to an old password], that may be the
    problem or if you have reinstalled the operating system. The associated EFS private
    key for the certificate must also be on the computer - the certificate will tell you
    that on the first/general page. You can use the efsinfo utility to find out who can
    decrypt the files and match certificate thumbprints if necessary. --- Steve

  3. You can download Efsinfo. There is the possibility that your EFS private key is
    corrupt which is why it is always recommended to export and save a copy of it. You
    might try to use cipher command to decrypt files [built in]. You also need at least
    list/read/execute ntfs permissions to the folder/files to be able to
    ncrytp/decrypt. --- Steve
