The file or directory is corrupted and unreadable

[DeskUser]

Hello

I have an asp.net application installed in several locations
(framework 1.1).

One of my clients is having a strange error when trying to access a
certain aspx page:
[IOException: The file or directory is corrupted and unreadable.
]

This error does not exist in any other pages.
Trying to replace the certain page and directory with with a copy that
works fine on different server
did not help.
The problem started after the server was restarted.
