Powershell 使用 CNAME 远程处理到服务器，而不是计算机名称

Question

我试图让 powershell 远程处理使用它的 CNAME 而不是计算机名称与服务器一起工作。本地和远程机器都在同一个网络和域中。

我启用了 powershell 远程处理，并且它与计算机名称一起工作正常。我已将 TrustedHosts 设置为 CNAME 并为 CNAME 添加了 SPN，但是当我发出时，Enter-PSSession CNAME我得到以下信息：

Enter-PSSession : Connecting to remote server CNAME failed with the following
error message : WinRM cannot process the request. The following error
occurred while using Kerberos authentication: Cannot find the computer CNAME.
Verify that the computer exists on the network and that the name
provided is spelled correctly. For more information, see the
about_Remote_Troubleshooting Help topic.

执行setspn -l COMPUTERNAME给了我这个：

Registered ServicePrincipalNames for CN=COMPUTERNAME,OU=SERVERS,DC=COMPANY,DC=private:
        WSMAN/CNAME
        WSMAN/COMPUTERNAME
        WSMAN/COMPUTERNAME.local
        TERMSRV/COMPUTERNAME
        TERMSRV/COMPUTERNAME.local
        HOST/COMPUTERNAME
        HOST/COMPUTERNAME.local

通过 CNAME 启用访问还需要什么？

我为解决这个问题所做的是为 Enter-PSSession 创建一个代理函数，为我解析 CNAME。这可能不适用于您的情况，具体取决于您为什么需要使用 CNAME，但这对我有用。

begin
{
    try {
        $outBuffer = $null
        if ($PSBoundParameters.TryGetValue('OutBuffer', [ref]$outBuffer))
        {
            $PSBoundParameters['OutBuffer'] = 1
        }
        $PSBoundParameters['ComputerName'] = ([System.Net.Dns]::GetHostByName($PSBoundParameters['ComputerName'])).HostName
        $wrappedCmd = $ExecutionContext.InvokeCommand.GetCommand('Microsoft.PowerShell.Core\Enter-PSSession', [System.Management.Automation.CommandTypes]::Cmdlet)
        $scriptCmd = {& $wrappedCmd @PSBoundParameters }
        $steppablePipeline = $scriptCmd.GetSteppablePipeline($myInvocation.CommandOrigin)
        $steppablePipeline.Begin($PSCmdlet)
    } catch {
        throw
    }
}

process
{
    try {
        $steppablePipeline.Process($_)
    } catch {
        throw
    }
}

end
{
    try {
        $steppablePipeline.End()
    } catch {
        throw
    }
}
<#

.ForwardHelpTargetName Enter-PSSession
.ForwardHelpCategory Cmdlet

#>

}

我添加的唯一一行是：

$PSBoundParameters['ComputerName'] = ([System.Net.Dns]::GetHostByName($PSBoundParameters['ComputerName'])).HostName

这只是在调用本机 Enter-PSSession 之前将 CNAME 解析为代理函数中的 FQDN。

这允许我通过组策略在我的 TrustedHosts 中设置 *.mydomain.local，并且我仍然可以使用“Enter-PSSession ShortName”或“Enter-PSSession CNAME”而不必弄乱额外的 SPN 等。
