Get-QADComputer The argument is null or empty.

Guys.

Looking for some assistance. Can anyone explain where i am going wrong? I am sure the get-qadcomputer part is working as it returns each workstation in the OU. However the $DefaultGateway code is like its not picking up the machine names?

Any ideas?

The code below =====

Get-QADComputer -SearchRoot "OU DN HERE" | ForEach-Object {$_.Name}

$DefaultGateway = (Get-wmiObject Win32_networkAdapterConfiguration -ComputerName $_.Name | ?{$_.IPEnabled}).DefaultIPGateway

$DefaultGateway

When i run the code i get the message below

Get-WmiObject : Cannot validate argument on parameter 'ComputerName'. The argument is null or empty. Supply an argument that

is not null or empty and then try the command again.
