We have been using symbolic links extensively to archive historic files.
An automatic script would create symbolic links regularly based on certain criteria. Users don't experience inconvenience as the soft links can be opened as regular files, programs will run without issues, and the type of those soft links are identical to the type of file it has a link to (for example, a symbolic link to an Excel file will have Excel file type in its properties).
However, recently we have noticed that the type of links have changed to SYMLINK which causes Windows to ask users to choose what program to open with by popping up the
Open With.. window.
What would cause the file server to change its behavior and represent symbolic links as SYMLINK?
