    Using Encryption on External Drive with Vista and 2003

    I have an external drive on which I keep files. If I encrypt files at home using Vista machine, backup certificate, import it on Windows 2003 Server machine and try to read files from Windows 2003 machine I can't do that.

    The reverse process works just fine. In other words files encrypted on Windows 2003 machine, its certificate is imported into Vista machine and vista can read those files.

    It is like Vista encryption is not exactly compatible with Windows 2003 encryption. Am I correct? How do I get the two to work with each other? Can I simply upgrade Windows 2003 encryption?

    I can't help with the built in encryption but have you considered
    another solution.
    Maybe something like Truecrypt to create an encrypted storage
    container...or PGP to encrypt individual files?

    I'll second Isaac's suggestion. The best way of making this work really well
    and reliably would be to use a 3rd party encryption product that works on
    all the OSes you need to use. Anything else leaves you at the mercy of every
    patch, hotfix and service pack in existence for either system to 'just tweak
    something'.

    I tried TrueCrypt. It looks reasonable.

    It still would be nice to know what went wrong between Vista and Windows
    2003 Server.

    I'm not sure anything is "wrong" as such as different systems written to
    different levels. Upgrading from one to the other might be fine but moving
    backwards and forewards is a different thing entirely. This is just my
    opinion/speculation, I certainly don't know for sure!

    Robert response is correct. This behavior is due to the many new
    capabilities that came with EFS in Vista. Your lower-level files can be
    modified at the Vista level but not vice versa. We are looking into this to
    see what we can do to make file sharing between versions more doable. Stay
    tuned.

    Thanks.

    I'm not sure where this thread will go...but I have just bought a new HP
    w/Vista. My "old" computer runs XP. I have most of the "old" hard drive
    encrypted with TrueCrypt. Will TrueCrypt work on Vista? Will I need a new
    version?

    TrueCrypt 4.3 works in vista. I have it working just fine with Flash Drive.
