Morning everyone,

Please can someone give a bit of instruction....

I want to get a list of servers from Active Directory (using Quest addins) and then for each server returned I want to ping it

So I have this:
================================================
$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 is Reachable
}
Else
{
Write-Host $Server is NOT reachable
}
}
============================================

The problem is that the result I get is this:
@{Name=servername} is NOT reachable

How do I change what I'm inputting to the ping piece so that it doesn't contain the column heading (property name) of 'Name'?

Many thanks :)

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
}
}

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
	}
}

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 <<<<  $_){
    + CategoryInfo          : ResourceUnavailable: (DOMAINNAME\'ServerName$:String) [Test-Connection], PingException
    + FullyQualifiedErrorId : TestConnectionException,Microsoft.PowerShell.Commands.TestConnectionCommand
 
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 <<<<  $_){
    + CategoryInfo          : ResourceUnavailable: (DOMAINNAME\'ServerName$:String) [Test-Connection], PingException
    + FullyQualifiedErrorId : TestConnectionException,Microsoft.PowerShell.Commands.TestConnectionCommand
 
Test-Connection : Testing connection to computer 'DOMAINNAME\'ServerName$' failed: The requested name is valid, but no data of the requested type was found

    + CategoryInfo          : ResourceUnavailable: (DOMAINNAME\'ServerName$:String) [Test-Connection], PingException

    + FullyQualifiedErrorId : TestConnectionException,Microsoft.PowerShell.Commands.TestConnectionCommand
 
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?

my mistake, here's an updated script:

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

Write-Host $_.name is Reachable

}Else{

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

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.

Does Powershell have you tied up in knots?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why
