Error message "A file name cannot contain any of the following characters: \ / : * ? " | # { } % ~ &", - invalid filename error, but no invalid characters

Hi,

As the title says: Error message "A file name cannot contain any of the following characters: \ / : * ? " < > | # { } % ~ &", - invalid filename error, but no invalid characters.

This is a problem who suddenly appeared for one user in a large network. He has a Windows 7 client [x86] and the error messages comes when he tried to change name on a shared folder [Windows 2008r2 server]. This is a sporadic problem, suddenly he is allowed to change the file name.

Anyone got a solution for this problem?
