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.

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
