Gentle HP 3000 Listers,

Recently there was a thread about denial-of-service problems with bad
TCP/IP datagram.  Microsoft has released a new version of PING which has
been updated to prevent this from occurring.  The file PINGUPD.EXE is
available at the Microsoft website.  If you have problems finding the file,
let me know and I can e-mail it to you.

Here is the information contained in the knowledge base:

======================================================================
---------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows 95
 - Microsoft Windows 95 OEM Service Release versions 1, 2, 2.1
---------------------------------------------------------------------

SYMPTOMS
========

When you use the Ping tool (Ping.exe) to test IP communication to a
network resource, the networked computer or other device may stop
responding (hang), or other errors may occur.

CAUSE
=====

Under some conditions, it is possible for the version of Ping.exe included
with Windows 95 to send an IP packet that would be considered an invalid
IP datagram. This may cause some systems to hang or encounter other errors.

RESOLUTION
==========

This issue is resolved by the following updated files for Windows 95:

   PING.EXE version 4.00.1381.3 (dated 12/14/96) and later
   MSVCRT.DLL version 4.20.6164 (dated 6/17/96) and later

These files are included in the self-extracting PINGUPD.EXE file.

The following file(s) are available for download from the Microsoft
Software Library:

 ~ Pingupd.exe
