server based shares\folders have desktop.ini file changed which hijacks users personal folders

we have a problem where users personal folders which are restricted by ntfs permissions have the desktop.ini file changes some how. when this file is changed & it matches another users desktop.ini file the users folder changes to mydoucments.  the current solution to solving this is delete the desktop.ini file in each of the offending user folders. then the folder name changes back to the users name.  this is becoming a real problem, in that scripting attempts to map to the users folder name and at times it has been hijacked and turned into my documents.
we think this might be related to windows7 os.  it seems that if a user logs onto a windows7 pc that their personal folder is highjacked teh next day.  one solution we have been implementing is delete the desktop.ini to have the user folder revert back to their name and then create a text file named desktop.ini and right protect the file.
any insight would be welcome.
thanks in advance.
