Don't be fooled - disabling null sessions will only prevent
non-authenticated users from being able to execute the attack.  Users with
accounts on the box (or the domain, depending on your situation) will
still be able to play bouncy-bouncy with the machine.

Read the Microsoft article (MS02-045) - it details all of this info.

Also note that this exploit works on unpatched XP and .NET servers as
well.
