No. In xp you don't password protect anymore as it offers less security. I
xp you turn off simple file sharing and then use security and permissions in
the file or folders properties to allow or deny access to the file or
folder. To turn off simple file sharing:
XP pro - explorer, folder options, view tab, uncheck: use simple file
sharing. Then, right click a folder or file, properties, security tab, set
as you like.
