需要从远程执行PowerShell脚本执行winrm set winrm / config / client'@ {TrustedHosts =“ 192.168.4.231”}'命令

Question

我正在从远程计算机触发以下脚本，以将执行者IP（192.168.4.231）添加到受信任列表中。但以下脚本被解雇了，但并非没有得到预期的结果。

请让我知道我在脚本下执行任何错误的方法。

$servers = @("192.168.4.236")
foreach($server in $servers) {
    $username = 'administrator'
    $password = '*******'
    $pw   = ConvertTo-SecureString $password -AsPlainText -Force
    $cred = New-Object Management.Automation.PSCredential ($username, $pw)
    $s = New-PSSession -ComputerName $server -Credential $cred
    Enter-PSSession $s
    Invoke-Command -Session $s -Scriptblock {
        Invoke-Expression 'winrm set winrm/config/client '@{TrustedHosts="192.168.4.231"}''
    }
    Write-Host "Completed"
    Remove-PSSession $s
}
