You have changed the RestrictAnonymous registry setting from 0 to 1 on your servers to secure your Windows 2000 system so that any malicious user cannot establish a null session on the server.

  • You cannot disable establishing null sessions.
  • You need to disable the promiscuous mode of network Ethernet card.
  • You need to set the RestrictAnonymous key value to 2 instead of 1.
  • You need to install a firewall.
