Powershell 如何以域管理员的身份使用Invoke命令在远程服务器上执行命令？

我正在尝试修改一个脚本，该脚本在手动在每台服务器上执行时会正常工作，以生成DFS复制，然后发送电子邮件，这样就可以从一个位置执行一次，然后远程连接到每台服务器

调用命令：

$ComputerName = Get-DfsrMember | Select-Object -ExpandProperty ComputerName -Unique | Sort-Object

$ComputerName | ForEach-Object {
    Try {
        $session = New-PSSession -ComputerName $_ -ErrorAction Stop
        Invoke-Command -ErrorAction Stop -Session $session -ScriptBlock {
          ## Script body starts here....
            Write-Host "Processing on server $($_) `n" -ForegroundColor Yellow
            Param (
             [String[]]$ReplicationGroupList = ("")
            )
         ....

        }
    }
    Catch [System.UnauthorizedAccessException] {
        Write-Warning "You do not have the proper access to this system!"
        Break
    }
    Catch [System.Runtime.InteropServices.COMException] {
        Write-Warning "Communications Exception occurred!"
        Break
    }
}

这是我收到的错误：

The term 'Param' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

以前正常工作但必须在每个服务器RDP会话中手动执行的实际Powershell脚本：

    $SelectedRGroups = @()
    foreach ($ReplicationGroup IN $ReplicationGroupList) {
        $SelectedRGroups += $rgroups | Where-Object { $_.ReplicationGroupName -eq $ReplicationGroup }
    }
    if ($SelectedRGroups.count -eq 0) {
        Write-Error "None of the group names specified were found, exiting"
        exit

Theo是正确的，Param（）代码需要是脚本块中的第一件事。您可以在这里找到有关脚本块的更多信息：

这是许多需要深入研究的代码。我建议开始学习或如何创建具有远程运行能力的高级函数。是的，我将找到一些方法使其工作，然后在较小的代码部分中进行更新。我认为

param（）

块应该是scriptblock中的第一件事。将行

Write Host“Processing on server$（$）”-ForegroundColor Yellow

移到param块下面。是的，这是有意义的。非常感谢，@Theo的启示。
