Carry over SID's during upgrade from Win2k

[Guest]

I recently upgraded a persons computer from Win2k to XP Pro. I didn't catch
his encrypted files until after the upgrade. What do I do now?

Without a backup of the original Encryption Certificate Key, encrypted files
are unrecoverable as they will stay encrypted forever. There is no recovery
method since the encryption algorithm is now completely different with a
reinstall of Windows XP.
