VERSIONS AFFECTED
Microsoft Windows 9x/Me
DESCRIPTION
A denial of service condition exists within Windows 9x/Me's NWLink protocol, where the Name Management Protocol on IPX (NMPI) may reply to network broadcast packets that should have been filtered out. Such a reply would cause other listening NWLink-enabled systems to also respond, which could lead to a large amount of network traffic. Systems may also crash under such conditions.
VENDOR RESPONSE
Microsoft has released a patch for Win95, Win98 and WinMe; FAQ# FQ00-073, and article Q273727.
