New Ping Tool Prevents Hanging Other TCP/IP Stacks

Q162542

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.

   PING.EXE version 4.00.1381.3 (dated 12/14/96) and later
