为什么这种使用共享文件夹的 DSC 文件资源只成功一次？

Question

我正在测试使用 DSC 文件资源将文件目录从共享文件夹复制到另一台计算机。

我的问题是，这可以工作一次，但运行第二次使用相同的代码会失败。如果我重新启动目标机器，脚本将再次运行正确但第二次失败。

谁能告诉我这是为什么，我是否需要做一些不同的事情？

我使用的机器叫：

"S1" => Server 2012 R2（具有读取权限的共享文件夹和用户设置）

"S2" => Virtual Server 2012 R2 运行ning on S1（这是目标机器）

我运行ning的脚本是这样的：

$ConfigurationData = @{
    AllNodes = @(
        @{
            NodeName="*"
            PSDscAllowPlainTextPassword = $true

        }
        @{
            NodeName = "S2"
        }
    )    
}

Configuration Test {

    param (
        [Parameter(Mandatory=$true)]
        [PSCredential]$credential
    )

    Node $AllNodes.NodeName {

        File DirectoryCopy {
            DestinationPath = "C:\Shared\Files"
            SourcePath = "\S1\Shared\Files"
            Ensure = "present"
            Credential = $credential
            Type = "Directory"
            Recurse = $true
        }
    }
}

$username = "dscUser"
$password="dscPassword!"|ConvertTo-SecureString -AsPlainText -Force
$credential = New-Object System.Management.Automation.PsCredential("$username",$password)

Test -OutputPath "C:\Scripts" -ConfigurationData $ConfigurationData -Credential $credential
Start-DscConfiguration -ComputerName S2 -path "C:\Scripts" -Verbose -Wait

这两次运行的输出是这样的：

感谢任何帮助，因为它让我抓狂。

谢谢。

Answer 1

我（认为）我找到了答案。

指定用户名时我应该使用 'S1\dscUser' 而不是 'dscUser'.

这些机器不在域中。
