First, the environment:
OS is Windows XP SP3
Computer is attached to an Active Directory Domain
User is in the local Power Users group
Now, the situation:
There are two files on the User's desktop, both Excel files.
She cannot open the files, even to just view them.
She gets a message advising the files are already opened or encrypted.
She was able to open them last week, and there have been no substantive changes on her workstation. Other staff are working normally, she's the only one affected at this point.
She cannot even save those files to a new location, we're talking copying, not moving. She just doesn't have rights to them, even though she has full rights to her desktop. She can create and/or delete new files, copy things from shared resources on the network and modify them on her desktop. It is only these files that are affected.
I attempted to make some security changes to those files (still logged in as her) and tried to force the changes down through the subfolders and objects on her desktop. Those changes would not apply to those spreadsheets. The system advised that access was denied.
Then, I added her to local Administrators and she was able to open the files with no issue.
I then took her back OUT of local Admins and things went back to the way they were.
Obviously a rights issue, but what am I missing?
She HAS full rights to her own desktop, one would assume that would mean full rights to any file ON her desktop too. These files are not linked from elsewhere, they are in her local profile's Desktop folder.
