Trying to restore shadow copies of files that have changed in error.
If on the file server (Windows 2008 r2) you drill down to the file that needs to be restored and right click "Restore previous version" no previous version show up. However if you right click on the parent directory and right click "Restore previous version" you can then open up a previous version of the directory and copy/open the file from that window.
Is there any reason why you cant just select the file with out having to go via the parent directory?
