我试图在远程Powershell会话上使用以下命令通过Chocolatey将无人看管的SQL Server 2017安装到Windows 10 Azure虚拟机中：
choco install sql-server-express -ia ""/IACCEPTSQLSERVERLICENSETERMS /FEATURES=SQLEngine /Q /ACTION=install /INSTANCEID=[INSTANCE_NAME] /INSTANCENAME=SQLCHEMETER /FILESTREAMLEVEL=1 /SECURITYMODE=SQL /SAPWD=[SA_PASSWORD] /UPDATEENABLED=FALSE"" -o -y"
但是安装失败，并且日志文件仅告诉我已引发此异常：

我已经检查过，启动它的用户具有管理员权限。
但是，只有在我之前没有连接到具有远程桌面的计算机时，这种情况才会发生，如果我先连接然后启动该过程，它将顺利进行。
问题在于，这必须是一个自动化过程，因此我无法与创建的计算机打开远程桌面连接。
有人对发生的事情有想法吗？
谢谢。

在放置赏金后不久，我自己想出了这个办法。 CredSSP可以解决问题，但它并不像单行代码那样简单。基本上，这是“双跳”问题，如果您不通过身份验证，则会遇到此错误。
要启用CredSSP，您需要在服务器（您要在其上安装SQL Server的远程主机）上运行它。
Enable-WSManCredSSP -Role Server -Force
您还需要在委托给服务器的计算机上启用CredSSP：
Enable-WSManCredSSP -Role client -DelegateComputer $nameOrIp -Force
此外，您需要在客户端上允许凭据委派，这可以使用以下脚本在PowerShell中自动完成：
$allowed = @("WSMAN/$nameOrIp")
$key = 'hklm:\SOFTWARE\Policies\Microsoft\Windows\CredentialsDelegation'
if (!(Test-Path $key)) {
md $key
}
New-ItemProperty -Path $key -Name AllowFreshCredentials -Value 1 -PropertyType Dword -Force
$key = Join-Path $key 'AllowFreshCredentials'
if (!(Test-Path $key)) {
md $key
}
$i = 1
$allowed |% {
New-ItemProperty -Path $key -Name $i -Value $_ -PropertyType String -Force
$i++
}
如果还没有，请确保两台计算机都将彼此设置为受信任的主机：
$curList = (Get-Item WSMan:\localhost\Client\TrustedHosts).value
$exists = $curList -match $nameOrIp
if ($exists -eq $false) {
"Adding IP to trusted hosts..."
Set-Item WSMan:\localhost\Client\TrustedHosts -Value "$curList, $nameOrIp" -Force
}
最后，使用现有的会话对我来说不起作用，我不得不改为将Invoke-Command与-Authentication CredSSP发送：
$cred = New-Object System.Management.Automation.PSCredential ($adminName, $secureWindowsPassword)
Invoke-Command -Computername $nameOrIp -Authentication CredSSP -Credential $cred -ScriptBlock {
Param($sqlPass)
Start-Process -FilePath C:\temp\SQLEXPR_x64_ENU.exe -Args "/ConfigurationFile=C:\temp\MSSQL.ini /SAPWD='$sqlPass' /Q /HIDECONSOLE /UpdateEnabled=FALSE" -Verb RunAs -Wait 4>&1
} -ArgumentList $sqlPass

在启动SQL Server安装程序之前，在powershell会话中运行此命令：
Enable-WSManCredSSP -Role "Server"
