+ The Distributed File System (or DFS) provides a means of separating the logical

+ This document explains how to host a DFS tree on a Unix machine (for DFS-aware
+ clients to browse) using Samba.
+ </p><p>
+ To enable SMB-based DFS for Samba, configure it with the <i class="parameter"><tt>--with-msdfs</tt></i>
+ option. Once built, a Samba server can be made a DFS server by setting the global
+ boolean <a href="smb.conf.5.html#HOSTMSDFS" target="_top"><i class="parameter"><tt> host msdfs</tt></i></a>

+ root using the share level boolean <a href="smb.conf.5.html#MSDFSROOT" target="_top"><i class="parameter"><tt>
+ msdfs root</tt></i></a> parameter. A DFS root directory on Samba hosts DFS
+ links in the form of symbolic links that point to other servers. For example, a symbolic link
+ <tt class="filename">junction->msdfs:storage1\share1</tt> in the share directory acts
+ as the DFS junction. When DFS-aware clients attempt to access the junction link,
+ they are redirected to the storage location (in this case, \\storage1\share1).
+ </p><p>
+ DFS trees on Samba work with all DFS-aware clients ranging from Windows 95 to 200x.
