How is the file encrypted by computer name?

[Guest]

I used my account login Windows XP which is in a domain. I encrypted a folder
include all subfolders and files a few days ago. I remembered I just changed
my password today. Then tried to decrypt the folder, the folder and all
subfolders with some files had been decrypted, however files under one
subfolder could not be decrypted.

I found the files which couldn't be decrypted were encryped by my computer
name instead of my account name. I compared with encrypted files under
another subfolder which were using my account name by checking advanced->
details.

I couldn't understand why is my computer name. So now I am not able to
decrypt the file at all. Any ideas would be really appreciated.

If you had offline files enabled, that might be related. See
