Per the title, I need a simple script to ping a list of IP addresses. If it helps, I am pinging a list of printers. But I would like to be able to use this for other systems as well.

Any how, I have a text file which contains a list IP's. I simply want ping output to display whether the host is online or not ( icmp replies or timeouts)

many thanks

Here is a sample code which will read a text file and display the server status on console..
GC C:\Temp\Server.txt | %{
	If (Test-Connection $_ -Quiet -Count 2){
	Write-Host "$_ is UP" -b Green
	}
	Else{
	Write-Host "$_ is Down" -b Red
	}
}

With small modification, you can save result in to a file..
GC C:\Temp\Server.txt | %{
	If (Test-Connection $_ -Quiet -Count 2){
	"$_ is UP"
	}
	Else{
	"$_ is Down"
	}
} | Out-File C:\Temp\result.txt

Open in new window

I like how the script operates...pretty cool. However, they appear to be "down" when in fact I can ping some of the addresses in my list

Thanks for prompt help. i removed the parameter..but it still shows red. They are printers, not servers. However, its just an IP we are talking about here so I am dumbfounded

ok.. Probably your input file have trailing space for IP addresses. Change the second line to..
	If (Test-Connection $_.Trim() -Quiet -Count 2){
