I assume you are talking about an in place upgrade. Possibly your private
key used for decryption has become corrupted. By default the built in
administrator account would be the recovery agent which is required in W2K.
If you have not tried it, log on as THE built in administrator to see if
that account can access the files. You may also try using the cipher command
to decrypt them.
You can restore a file to another computer, but you must logon as the same
user/password and your private key also needs to be available - not just the
certificate. If you exported/imported a .pfx file then the private key was
also included. It may also help to use the efsinfo command to view what
user/recovery agent can decrypt the files and view the thumbprint info for
the certificate that you can then try to match up to the certificate in the
users/reovery agents user certificate store available via mmc certificates
snapin for user. The thumprints must match. The link below may be
elpful. --- Steve
