SolutionBy default windows waits
for 4000(4seconds) for the Echo Reply message that corresponds to a
given Echo Request message to be received. If the Echo Reply message is
not received within this time-out, the "Request timed out" error message
is displayed.
This setting can be changed using
the –w switch. The timeout can be set to 999 milliseconds or lower, but
windows will never try more frequently than once per
second.
ping x.x.x.x –t –w
999
This can be helpful while
troubleshooting performance issues and Ping is the basic tool to check
the percentage loss.
While testing with ping command,
the odd missing ping is acceptable. However the frequency of miss should
not be greater than 1 per second. But by default, on a windows machine
this stretches to 1 per four seconds due to the fact windows waits for a
response to timeout before sending the next
ping.
In such scenarios, the
above command can be used to reduce the timeout
value.
