Question

尝试在PowerShell中运行Add-DhcpServerv4Reservation命令时，我一直收到以下错误：

+ CategoryInfo          : NotSpecified: (xxx.xxx.42.234:root/Microsoft/...erv4Reservation) [Add-DhcpServerv4Reservation], CimException
+ FullyQualifiedErrorId : WIN32 1753,Add-DhcpServerv4Reservation

（xxx具有IP地址的实际数量）

当我尝试单独运行命令时出现此错误：

Add-DhcpServerv4Reservation -Name test -ScopeId xxx.xxx.40.0 -IPAddress xxx.xxx.42.234 -ClientId 01-01-01-01-01-01 -Description computer -Type DHCP

以及以下脚本：

Import-Module DHCPServer
clear
$IP = Read-Host "Please type in the IP Address of the computer you would like to add"
clear
try {
    $ReservationObj = Get-DhcpServerv4Reservation -ComputerName xxx.xxx.40.4 -IPAddress $IP -ErrorAction Stop

    $Person = New-Object PSOBJECT
    $Person | Add-Member "Device Name" $ReservationObj.GetCimSessionComputerName
    $Person | Add-Member User $ReservationObj.Description
    $MAC = $ReservationObj.ClientId
    $MAC = $MAC -replace "-", ":"
    $Person | Add-Member "MAC Address" $MAC
    $Person | Add-Member "IP Address" $IP

    Write-Output $Person | Format-List
} catch {
    Write-Host "This IP address is not currently reserved and is available for use."

    $Response = Read-Host "Would you like to add a new reservation for this IP address (yes)/(no)?"
    if ($Response -eq "yes") {
        $Description = Read-Host "Please enter the Manufacturer and Model of the device as well as it's owner (i.e its description)"
        $MAC = Read-Host "Enter the computers MAC address (xx-xx-xx-xx-xx-xx)"
        $Computer = Read-Host "Enter in the computer name."

        Add-DhcpServerv4Reservation -Name $Computer -ScopeId xxx.xxx.40.0 -IPAddress $IP -ClientId $MAC -Description $Description -Type DHCP
        Write-Host $Computer "has been added"
    } else {
        Write-Host "Nothing has been added"
    }
}

再次将xxx替换为实际数字，我刚才没有在这篇文章中包含实际数字。

任何人都知道为什么会出现这种错误？

Answer 1

根据https://technet.microsoft.com/en-us/library/jj590690(v=wps.630).aspx，参数“ComputerName”指定要在其中创建预留的DHCP服务器。如果您在此处传递客户名称，则会导致此错误。几分钟前发生在我身上，因为我把“Computername”和“Description”搞混了。

Answer 2

我知道这个答案来得有点晚，但是我发现在-ClientID参数中，MAC地址必须为小写字母，并且只能包含字母和数字（不带连字符）。

一个好的MAC地址示例：00155D36C906

命令示例：

Add-DhcpServerv4Reservation -ScopeId 10.10.10.0 -IPAddress 10.10.10.2 -ClientId 00155D36C906 -Description "Test device" -Name "Test"

Add-DhcpServerv4Reservation FullyQualifiedErrorId：WIN32 1753
