RE: Decrypt File

You may be out of luck.

If your W2K system is a member of a domain and you have Cert Services
running, you probably tied your encrypt/decrypt key to your domain
account.  There is also a recovery agent key created and it may be
assigned to someone in your company.

On the other hand, if this is a standalone workstation you are in
trouble.  When you use EFS on a standalone box, two copies of the
encrypt/decrypt keys are created.  One is tied to the user account that
did the encryption and the other to the local Admin account.

If you did a full backup and restore (including all of the W2K system
files) this should work.  If you only backed up your data files and then
wiped and rebuilt the system, it is not going to work as you wiped out
the encrypt/decrypt keys when you wiped out the OS.

Sorry...
