Exception calling "Send" with "1" argument(s) error using PING

I have a PowerShell script which uses the System.Net.NetworkInformation.Ping
object. It reads thru a text file of hostnames and does a PING test. What
I'm curious about is that I get this error every now and then, meaning no
error on first three hostnames from the list, error on the next, etc.

Exception calling "Send" with "1" argument(s): "An exception occurred during
a Ping request."
At line 5, position 22
$Reply = $ping.send($strComputer)

A forum post from the MSDN forum says its by design.

Am I missing something?

It made sense to me and I'm not even a .NET developer. Couldn't you simply use an error trap and if you get that error, then know you can't ping that computer for some reason.

A ping alternative is to use the win32_pingstatusclass:

PS C:\> get-wmiobject -query "Select * from win32_pingstatus where address='godot'"

Thanks for the inputs. I'm trying to monitor computers and servers, check
if they're running before I run a script. I'm trying to convert all of my
VBScripts to PowerShell :-)

Here's a function that might help.

This is designed to take pipeline input.

"localhost" | ping-host
or
get-content servers.txt | ping-host

If the computer can be pinged, the name is written to the pipeline. Moving from VBScript to PowerShell requires a paradigm shift as much as anything.

If you're computers are setup to not respond to ICMP echoes you can try this,
I can't remember where I found it at the moment.

function Test-Port
{
param([string]$srv,$port=135,$timeout=750,[switch]$verbose=$false)
$ErrorActionPreference = "SilentlyContinue"
$tcpclient = new-Object System.Net.Sockets.TcpClient
$iar = $tcpclient.BeginConnect($srv,$port,$null,$null)
$wait = $iar.AsyncWaitHandle.WaitOne($timeout,$false)
if(!$wait)
{
$tcpclient.Close()
if($verbose){Write-Host "Connection Timeout"}
Return $false
}
else
{
$error.Clear()
$tcpclient.EndConnect($iar) | out-Null
if($error[0]){if($verbose){write-host $error[0]};$failed = $true}
$tcpclient.Close()
}
if($failed){return $false}else{return $true}
}

This will allow you to specify a specific port on a specific machine. I use
it to see if the ports for telnet, ssh, etc.. are open so i can close them.
But you could use it instead of a ping.

It says "Press Any Key To Continue..." but I can''''t find the "Any" key......
