Having been asked plenty of times, here’s the type extension I added to create the CanPing property for the String type:
<Type>
<Name>System.String</Name>
<Members>
<ScriptProperty>
<Name>CanPing</Name>
<GetScriptBlock>
$wmi = get-wmiobject -query “SELECT * FROM Win32_PingStatus WHERE Address = ‘$this'”
if ($wmi.StatusCode -eq 0) {
$true
} else {
$false
}
</GetScriptBlock>
</ScriptProperty>
</Members>
</Type>
Note that this SHOULD be dropped into a standalone .ps1xml file as follows:
<Types>
<Type>
<Name>System.String</Name>
<Members>
<ScriptProperty>
<Name>CanPing</Name>
<GetScriptBlock>
$wmi = get-wmiobject -query “SELECT * FROM Win32_PingStatus WHERE Address = ‘$this'”
if ($wmi.StatusCode -eq 0) {
$true
} else {
$false
}
</GetScriptBlock>
</ScriptProperty>
</Members>
</Type>
</Types>
And imported into PowerShell using the Update-TypeData cmdlet. Then, just do this:
[string]$name = “ServerA”
$name.CanPing
To see if it’s pingable or not. Hmm… bet this could be adapted into a cmdlet-like function which takes a list of names and only outputs those which ARE pingable…
