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.

Thanks I am glad to hear that Microsoft is working on this issue.
