EFS blocking users from accessing their encrypted files M Skabialka 06-06-2007

When we upgraded the server from Server 2000 to 2003 there were some user
documents that were encrypted (not sure if before or after the upgrade).
The users are now unable to decrypt the files, copy or even read them, and
even though I took ownership of one of the files (as a test) as the domain
admin, neither can I.
The error message when trying to decrypt is: "An error occurred applying
attributes to the file: \XXX\xxx\file.doc. This machine is disabled for
file encryption."
When trying to copy: "Cannot copy file.doc: Access is denied. Make sure
that the disk is not full or write-protected and that the file is not
currently in use."
NTBackup does not back the encrypted files up, saying they are in use, which
they aren't. "Warning: The file \Documents and Settings\ABC\My
Documents\file.doc in use - skipped."
Under file properties, general, Attributes, Advanced, Encrypt contents to
secure data is checked, but when I click Details, A window titled EFSADU
pops up saying "Unable to find the user information for the file." and the
option to add users is grayed out. No data recovery agents are listed.
We have tried turning encryption on and off on the server and rebooting each
time but nothing works. The users is on Win XP Pro, where encryption works.
How can we solve this problem?

Thanks,
Mich

Have you tried running EFSINFO (support tool) to see what shows up on the
folder ?
