爲什麼使用共享文件夾使用DSC文件資源只能成功一次？

Question

我正在測試使用DSC文件資源將共享文件夾中的文件目錄複製到另一臺機器。

我的問題是，這一次工作，但第二次失敗時運行相同的代碼。如果我重新啓動目標計算機，腳本將再次正常運行但再次失敗。

誰能告訴我爲什麼這是，我是否需要做一些不同的事情？

我使用的機器被稱爲：

「S1」=>服務器2012 R2（這對於讀訪問的共享文件夾和用戶設置）

「S2」=>虛擬服務器2012 R2在S1運行（這是目標機器）

我運行的腳本是這樣的：

$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 

運行此的輸出兩次是這樣：

任何與此有關的幫助表示讚賞，因爲它驅使我瘋了。

謝謝。

Answer 1

我（想）我找到了答案。

當指定的用戶名我應該使用的'S1 \ dscUser'，而不是 'dscUser'。

這些機器不在一個域中。
