     On Windows 2000 and Windows XP UDP port 445 is opened but I don't =
think it is used or don't know how if it is.   On Windows Server 2003 =
UDP port 445 is not open.  Look at =

you'll see that TCP 445 is mentioned but UDP 445 is not.  The Windows =
Firewall in Windows XP and Windows Server 2003 also associates TCP 445 =
only with SMB.

       It isn't.  If you see it used, it is something unrelated.

      If I understand correctly, TCP port 445 is used in Windows to =
support SMB
      hosted directly over TCP rather than over NBT. What I don't =
understand is
      how UDP port 445 is used. SMB over UDP?
