Powershell get computers list and ping

why using wmi to ping when u can use testconnection?

Get-QADComputer -Searchroot 'mydomain.com/servers'  | foreach{
If (Test-Connection $_){ 

Write-Host $_.name is Reachable

}Else{

Write-Host $_.name is NOT reachable
}
}

Select allOpen in new window

also u have a mistake in your script:

instead of:
$Alive=Get-WMIObject win32_pingstatus -Filter "Address-'$Server'" |Select-Object

should be:
Alive=Get-WMIObject win32_pingstatus -Filter "Address='$Server'" |Select-Object

here's your script updated:

$ProdServer=Get-QADComputer -Searchroot 'mydomain.com/servers' |Select-Object name
forEach ($Server in $ProdServer)
{

	$Alive = Get-WMIObject win32_pingstatus -Filter "Address='$Server'" |Select-Object statuscode 

	if ($Alive.statuscode -eq 0)
	{
		Write-Host $Server.Name is Reachable
	}
	Else
	{
		Write-Host $Server.Name is NOT reachable
	}
}

Select allOpen in new window

Hi Sedgwick,

I'm learning Powershell and wasn't aware of test-connection.  This looks good.  Kind of the same really. But I'll investigate that more: )

Sadly, running your script with test-connection gives me this result:
=========================================
Test-Connection : Testing connection to computer 'DOMAINNAME\'ServerName$' failed: The requested name is valid, but no data of the requested type was found
At line:2 char:20
+ If (Test-Connection <<<<  $_){

ServerName is NOT reachable
===========================================

ALL instances of 'ServerName' are referring to the same server. Notice the very last entry also. This is bizarre because 'servername' is reachable.

Can you explain what's going on and what causes these multiple entries?

Many tanks

if u still get errors when using test-connection, use your script instead with the changes i've made.

Sedgwick,

This is brilliant many thanks.  Your script is working fine.  I see that it works because we're doing 'Test-Connection' against only the property named 'name'.

Thanks awfully for your help.

Tommy

u welcome.

cheers
