Question

我创建了以下过程以获取远程计算机上已安装程序的列表。我在我的计算机上测试它并且工作正常，但是当我尝试在我的网络中使用时，我收到以下错误。

我正在以网络管理员身份运行它。

代码：

Invoke-Command -ComputerName brpgd008 {
  Get-ItemProperty HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\* |
    Select-Object DisplayName, DisplayVersion, Publisher, InstallDate |
    Format-Table –AutoSize > \\brspd010\c$\users\machael1\desktop\product1.txt
}

错误：

error:[brpgd008] Connecting to remote server failed with the following error
message : WinRM cannot process the request. The following error occured while
using Kerberos authentication : A specified logon session does not exist. It may
already have been terminated.
Possible causes are:
  -The user name or password specified are invalid.
  -Kerberos is used when no authentication method and no user name are specified.
  -Kerberos accepts domain user names, but not local user names.
  -The Service Principal Name (SPN) for the remote computer name and port does
   not exist.
  -The client and remote computers are in different domains and there is no trust
   between the two domains.
After checking for the above issues, try the following:
  -Check the Event Viewer for events related to authentication.
  -Change the authentication method; add the destination computer to the WinRM
   TrustedHosts configuration setting or use HTTPS transport.
Note that computers in the TrustedHosts list might not be authenticated.
   -For more information about WinRM configuration, run the following command:
    winrm help config. For more information, see the about_Remote_Troubleshooting
    Help topic.

Answer 1

正如许多其他人指出的那样，您的问题是您无法通过WinRM创建PSSession。 PSRmoting over WinRM是Invoke-Command使用的。解决此问题的最简单方法是在远程主机上运行Enable-PSRemoting。有许多指南可以通过组策略等方式在您的环境中进行配置。

话虽如此，您可以使用与WinRM不同的方法来轮询这些注册表值。例如，您可以使用[Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey()（我相信使用Remote Registry服务）：

$ComputerName = "brpgd008"
$RegLocation = "Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\"
$Values = "DisplayName", "DisplayVersion", "Publisher", "InstallDate"
$Reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $ComputerName)

$RegKey= $Reg.OpenSubKey($RegLocation)
$SubKeys = $RegKey.GetSubKeyNames()

foreach ($SubKey in $SubKeys) {
    $Output = New-Object -TypeName PSObject
    $LeafKey = $Reg.OpenSubKey("$RegLocation$SubKey")
    Foreach ($Value in $Values) {
        Add-Member -InputObject $Output -MemberType NoteProperty -Name $value -Value ($LeafKey.GetValue($Value))
    }
    $Output
}

作为旁注，请记住，在x64系统上，您需要在WOW6432Node中检查32位应用。
