Selection of only one user from list-CodePudding

I have this script that I need to use to retrieve the data of a particular user "ADTuser" from a list of servers the script works well, but the output file with my user add also other users' detail that is not needed for my final output how can I filter it to only the user that I need.

get-content C:\servers.txt | foreach-object { 
    $Comp = $_ 
    if (test-connection -computername $Comp -count 1 -quiet) { 
        ([ADSI]"WinNT://$comp").Children | ?{$_.SchemaClassName -eq 'user' } | %{ 
            $groups = $_.Groups() | %{$_.GetType().InvokeMember("Name", 'GetProperty', $null, $_, $null)} 
            $_ | Select @{n='Computername';e={$comp}}, 
            @{n='UserName';e={$_.Name}}, 
            @{n='Memberof';e={$groups -join ';'}},
            @{n='status'; e={if($groups -like "*Administrators*"){$true} else{$false}}}
        }  
    } Else {Write-Warning "Server '$Comp' is Unreachable hence Could not fetch data"} 
} | Out-File -FilePath C:\users.txt

This should be an easier way of doing what you're looking for, Get-CimInstance and Get-CimAssociatedInstance have been around since PowerShell 3 if I'm not mistaken:

Get-Content C:\servers.txt | ForEach-Object {
    $computer = $_
    try {
        $query = Get-CimInstance Win32_UserAccount -ComputerName $_ -Filter "Name='ADTuser'" -ErrorAction Stop
        if(-not $query) { return }
        $membership = Get-CimAssociatedInstance $_ -ResultClassName Win32_Group -ComputerName $_

        [pscustomobject]@{
            Computername = $_
            UserName     = $_.Name
            Memberof     = $membership.Name -join ';'
            Status       = $membership.Name -contains 'Administrators'
        }
    catch {
        Write-Warning "Server '$computer' is Unreachable hence Could not fetch data"
    }
} | Out-File C:\users.txt

If that doesn't work for you, your code would require a simple modification on your first filtering statement:

Where-Object { $_.SchemaClassName -eq 'user' -and $_.Name.Value -eq 'ADTuser' }

Putting it all together with minor improvements:

Get-Content C:\servers.txt | ForEach-Object {
    if (-not (Test-Connection -ComputerName $_ -Count 1 -Quiet)) {
        Write-Warning "Server '$_' is Unreachable hence Could not fetch data"
        return
    }
    
    $computer = $_
    ([adsi]"WinNT://$_").Children.Where{
        $_.SchemaClassName -eq 'user' -and $_.Name.Value -eq 'ADTuser'
    }.ForEach{
        $groups = $_.Groups().ForEach{ $_.GetType().InvokeMember("Name", 'GetProperty', $null, $_, $null) } 
        
        [pscustomobject]@{
            Computername = $computer
            UserName     = $_.Name.Value
            Memberof     = $groups -join ';'
            Status       = $groups -contains 'Administrators'
        }
    }
} | Out-File -FilePath C:\users.txt
