Hello all,
I am trying to write a script to query the registry for a list of comptuers and put the information into a csv.

The trouble I am having is with the ping.send or test-connection when I hit a machine that isn't in dns.

I can't get it to continue gracefully no matter what I try so I am hoping one of you Posh Guru's will point out what I could be doing.

Thanks to Shay Levy and his PSRemoteRegistry Module.  I like the test-connection -computername $computer -quiet as it will continue on false but for some reason i can't pass true into the rest of the script.

Thanks.

$WMIFailure = @()

$AllComputers += $ComputerObj


foreach ($Computer in $Computers)
{
#Ping each server to check that it's alive
$ping = ""
$ping = Test-Connection -ComputerName $Computer -Quiet -Count 1

There is an error with the way you are using Test-Connection. Change it to this:

foreach ($Computer in $Computers)
{
    #Ping each server to check that it's alive
    $success = Test-Connection -ComputerName $Computer -Quiet -Count 1
   
    if ($success)
    {
      ...

When you specify the -Quiet switch, Test-Connection returns a Boolean, not a PingReply object.
