How to copy a folder via smb only to turned on computers?

Question

PowerShell

I found sample scripts on the net. Enabled WinRM via logon script.
When I try to copy over a network share from a domain controller through a powershell script, I get an error:

$computername = (Get-ADComputer -LDAPFilter "(&(objectCategory=computer)(!userAccountControl:1.2.840.113556.1.4.803:=8192))" -Properties name | Sort).name;
$src = "\\DC-01\c$\zabbix\*"

foreach ($computer in $computername) 
{
    $df = "\\$computer\c$\zabbix"


    if (!(Test-Path -path $df))
    {
        New-Item $df -Type Directory
    }
    Copy-Item -Path $src  -Destination $df;
    Invoke-Command -ComputerName $computer -ScriptBlock {powershell "& 'C:\zabbix\install.bat'"}

How to copy a folder ONLY to turned on PCs?
And yet, PC DNS names are truncated, how to fix it?

Answer 1

If you answer based on the question - you can check the availability of the node using Test-NetConnection .
The rest of the things (DNS names are truncated - what is it about? Where?) It is better to discuss in the comments.

Answer 2

Is it not an option to install the zabbix agent through GPO?
PS what will the script do if the computer is turned on and the agent is already installed?
