+	/// There are hundreds of error codes that may be returned by a CIFS
+	/// server. Rather than represent each with it's own <code>Exception</code>
+	/// class, this class represents all of them. For many of the popular
+	/// error codes, constants and text messages like "The device is not ready"
+	/// are provided.
+	/// <p>
+	/// The jCIFS client maps DOS error codes to NTSTATUS codes. This means that
+	/// the user may recieve a different error from a legacy server than that of
+	/// a newer varient such as Windows NT and above. If you should encounter
+	/// such a case, please report it to jcifs at samba dot org and we will
+	/// change the mapping.
