使用 CSV 文件和 Mac 地址重命名计算机

Question

我正在尝试设置在 MDT 任务序列期间运行 PowerShell 脚本时检查的主 CSV 文件。该脚本试图做的是获取物理连接的网卡的 MAC 地址，并将其与 CSV 文件进行比较，以查看它是否与文件中保存的 Mac 地址匹配。如果 mac 地址与 CSV 中的值匹配，则会将计算机重命名为与 Mac 地址配对的值。如果没有匹配则根据计算机序列号重命名。

这里是我的一些东西。

$computer = Get-WmiObject Win32_ComputerSystem -ComputerName $oldname
#$Machost is Mac Address of the active Network Card
$MacHost=Get-NetAdapter -Name "Ethernet" | Select Macaddress

$ConvertMacHost= $MacHost[0] -replace '(:|-|\.)'
Write-Host "You mac address is: " $MacHost
#MacHost gets reformatted to take out Semicolons - Ex 0011223344AA


#MacLab is a variable that stores the Computer name and Mac Address from File created in Deep Freeze that matches Mac Address of host.
#MacLab is formated to make all Alpha in Mac Address Capitalized 
$MacLab=Import-Csv 'C:/projectcsv/LH_office.csv' | Select Workstations,@{Label ="Mac Address"; Expression ={$_."Mac Address".ToUpper()}}|where-object {$_."Mac Address" -eq $ConvertMacHost}|Select Workstations

#Checks to see if Host Mac Address Matches CSV File
If ([string]::IsNullorEmpty($MacLab))
{

    Write-Warning  -Message "No Mac Address found in our Records that Match the Host Machine Mac Address: Exit code 11001"  
    write-host "" 
    exit 11001
   
    }Else{
        
$strUser = "******\domainadd"
$strDomain = "******"
$strPassword = ConvertTo-SecureString "*******" -AsPlainText -Force
$Credentials = New-Object System.Management.Automation.PsCredential $strUser,
$strPassword

#---- Define Prefix to be used -----#
$strPrefix='LH'
$strEnding='DESK'

#----- Get Serial Number ------#

$SN=(gwmi win32_BIOS).serialnumber

#--If working with VM, the SN length is longer than 15 Char------#
if($SN.length -gt 11) {
    #Get the last 7 Char of Serial
    $StrName=($SN.substring($SN.length - 11)) -replace "-",""
           
            $strComputerName=$strPrefix+"-"+$StrName+"-"+$strEnding
    } else {$strComputerName=$strPrefix+"-"+$SN+"-"+$strEnding

    }

    #------ Rename the Computer using WMI --------#
    #$computer=gwmi win32_computersystem
    #$computer.rename($strComputerName)

    #-----Powershell 5 above use-------#

    rename-computer -NewName $StrComputerName -PassThru -DomainCredential $Credentials

当我运行代码时，我收到以下错误消息：

我将正在使用的计算机添加到 csv 中，但仍然出现错误。我知道以后我必须添加函数来检查名称是否已经在 AD 中。但想让它先工作。请您提供任何帮助。

编辑：这是 CSV 文件的图片，显示了其中的信息。

在进行建议的更正后，脚本运行时出现这些错误。

Answer 1

$MacHost 正在接收具有属性的对象，因此您需要指定所需的属性，否则会得到奇怪的结果，这会导致 Where-Object 失败。

具体来说，$ConvertMacHost 最终变成了类似于@{MacAddress=9CB6D0959AE5}

这一行

$ConvertMacHost= $MacHost[0] -replace '(:|-|\.)'

应该是

$ConvertMacHost= $MacHost[0].MacAddress -replace '(:|-|\.)'
