如何在远程计算机上通过 WMI 更改 LogFile.Directory 属性？

Question

我能够使用 WMI 检索位于远程计算机上的特定 IIS 站点的 LogFile.Directory 值。 现在我需要更改LogFile.Directory 属性——这是自动化过程中的一个步骤——但我碰壁了。这是我目前所拥有的，虽然它不起作用。

    Write-Output "Making IIS connection to $($XmlCloudNodeFullyQualifiedDomainName)"
    $site = Get-WmiObject -ComputerName $XmlCloudNodeFullyQualifiedDomainName -Namespace "root/webadministration" -Class Site -Authentication 6 -Filter "Name = '$IISSiteName'"
    If ($site.Name -eq $IISSiteName) { 
        Write-Output "Found site $IISSiteName"
        Write-Output ("Existing log folder: " + $site.LogFile.Directory)
        $newLogFolder = "E:\" + $IISSiteName + "\logs"
        Write-Output ("Set IIS log folder to " + $newLogFolder)
        $site.LogFile.Directory = $newLogFolder
        $site.Put()
    } 

我没有收到任何错误。当我签入 IIS 管理器时，远程计算机上的 LogFile.Directory 值不会改变。 我读到我应该改用Set-WMIInstance，所以我尝试了：

    Write-Verbose "Making IIS connection to $($XmlCloudNodeFullyQualifiedDomainName)"
    $site = Get-WmiObject -ComputerName $XmlCloudNodeFullyQualifiedDomainName -Namespace "root/webadministration" -Class Site -Authentication 6 -Filter "Name = '$IISSiteName'"
    $sitePath = (Get-WmiObject -ComputerName $XmlCloudNodeFullyQualifiedDomainName -Namespace "root/webadministration" -Class Site -Authentication 6 -Filter "Name = '$IISSiteName'").__path
    If ($site.Name -eq $IISSiteName) { 
        Write-Output "Found site $IISSiteName"
        $newLogFolder = "E:\" + $IISSiteName + "\logs"
        Write-Output ("Existing log folder: " + $site.LogFile.Directory)
        Set-WmiInstance -Path $sitePath -argument @{LogFile.Directory = $newLogFolder}
        Write-Output ("Set IIS log folder to " + $newLogFolder)
    }

但这会引发错误：

At E:\\Test.ps1:71 char:54
+             Set-WmiInstance -Path $sitePath @{LogFile.Directory = $newLogFolder}
+                                                      ~
Missing '=' operator after key in hash literal.
At E:\\Test.ps1:72 char:18
+             Write-Output ("Set IIS log folder to " + $newLogFolder)
+                  ~
Missing '=' operator after key in hash literal.
At E:\\Test.ps1:41 char:54
+     foreach ($FSMappingNode in $FSMappingNodesArray) {
+                                                      ~

有没有办法远程更改这个特定值，或者它是只读属性？ 任何帮助将不胜感激。 谢谢，

折腾了好久，终于找到了远程修改IIS站点LogFile.Directory的方法：

    Write-Output "Making IIS connection to $($XmlCloudNodeFullyQualifiedDomainName)"
    $site = Get-WmiObject -ComputerName $XmlCloudNodeFullyQualifiedDomainName -Namespace "root/webadministration" -Class Site -Authentication 6 -Filter "Name = '$IISSiteName'"
    $sitePath = $site.__path
    Write-Verbose $sitePath
    If ($site.Name -eq $IISSiteName) { 
        Write-Output "Found site $IISSiteName"
        Write-Verbose ("Existing log folder: " + $site.LogFile.Directory)
        $newLogFolder = "E:\" + $IISSiteName + "\logs"
        $siteLogFile = $site.LogFile
        $siteLogFile.Directory = $newLogFolder
        Set-WmiInstance -Path $sitePath -Arguments @{LogFile = $siteLogFile}
        Write-Output ("Set IIS log folder to " + $siteLogFile.Directory)
    }
