Windows clients need to be rebooted if a previously mounted non-DFS share is made a DFS root, or vice versa. A better way is to introduce a new share and make it the DFS root.

Currently, there's a restriction that msdfs symlink names should all be lowercase.

For security purposes, the directory acting as the root of the DFS tree should have ownership and permissions set so only designated users can modify the symbolic links in the directory.
