Now I am trying "Nslookup" monitoring with scripting. But I cannot execute the script. There is no error message, but it took too long yet noting displayed. But once I run the script the attention about "Windows Script Host" is pop up. Here is my script. Any Idea?? 

Command line - cmd /c powershell.exe -ExecutionPolicy RemoteSigned .\${FileName}.ps1 ${DeviceName} "ip address" 

Script body - $deviceName = $args[0]

$dnsServer = $args[1]

$exitcode = 1

$output = nslookup www.google.com $dnsServer

for($i=0; $1 -lt $output.Length; $i++)

{

$t = $output[$i].Spilt(":")[1]

if($t -ne $null -and $t.Contains($deviceName))

{

$exitcode = 0

break

}

if($exitcode -eq 1)

{

Write-Host Message:Lookup failed for $deviceName

}

else

{

Write-Host Message:Lookup succeeded for $deviceName

}

}

Anyone can help me solve this problem? Many many thanks. 

Regards,

Rita
