Powershell使用CNAME（而不是COMPUTER NAME）远程服务器

我正在尝试使Powershell远程处理以使用服务器的CNAME（而不是计算机名）来工作。本地和远程计算机都在同一网络和域上。

我已启用Powershell远程处理，并且可以与计算机名称一起正常工作。我已将TrustedHosts设置为CNAME，并为CNAME添加了SPN，但是当我发出Enter-PSSession CNAMEI时，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

要通过CNAME进行访问还需要什么？

解决此问题的方法是为Enter-PSSession创建一个代理功能，该功能为我解析了CNAME。根据您需要使用CNAME的原因，这可能不适用于您的情况，但这对我有用。

功能齐全：

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

只需在调用本机Enter-PSSession之前将CNAME解析为代理功能中的FQDN。

这使我可以通过组策略在TrustedHosts中设置* .mydomain.local，并且我仍然可以使用“ Enter-PSSession ShortName”或“ Enter-PSSession CNAME”，而不必与其他SPN混为一谈。
