POSIX on Windows network shares

Reading through the mount.cifs(8) man page, I read about support for POSIX semantics (permissions, ownership, xattrs, and so on) in the Common Internet File System (CIFS) used by Microsoft file servers.

I have a couple of Windows PCs here that are sharing their disk drives via CIFS. My question is if Windows XP supports POSIX semantics on network shares out of the box or if some option needs passed to mount.cifs, or if the Microsoft SFU (Services for Unix) software needs installed, or if I have no options for getting POSIX-like behavior out of a CIFS mount on a Windows XP (Professional SP2) server.

The shares are NTFS volumes.
