Powershell 远程处理 - 策略不允许委派用户凭据

Question

我是 powershell 新手，我在使用凭据委派时遇到了麻烦。我有以下脚本:

$session = New-PSSession myserver -Authentication CredSSP -Credential DOMAIN\Administrator
Invoke-Command -Session $session -ScriptBlock { <Some PowerShell Command> }

在运行它之前，我做了以下事情:

运行Enable-PSRemoting在我的服务器上。

运行Enable-WSManCredSSP Server在我的服务器上。

运行Restart-Service WinRM在我的服务器上。

运行Enable-WSManCredSSP Client –DelegateComputer myserver在客户端。

重新启动服务器和客户端。

但是一旦我运行脚本，我会收到以下错误消息:

[myserver] Connecting to remote server failed with the following error message : The WinRM client cannot process the request. A computer policy does not allow the delegation of
 the user credentials to the target computer. Use gpedit.msc and look at the following policy: Computer Configuration -> Administrative Templates -> System -> Credentials Delega
tion -> Allow Delegating Fresh Credentials.  Verify that it is enabled and configured with an SPN appropriate for the target computer. For example, for a target computer name "m
yserver.domain.com", the SPN can be one of the following: WSMAN/myserver.domain.com or WSMAN/*.domain.com. For more information, see the about_Remote_Troubleshooting Help topic.
    + CategoryInfo          : OpenError: (System.Manageme....RemoteRunspace:RemoteRunspace) [], PSRemotingTransportException
    + FullyQualifiedErrorId : PSSessionOpenFailed

我检查了错误消息中提到的政策，但一切似乎都很好。还有什么能阻止我？

Answer 1

在服务器上执行以下操作:

Enable-WSManCredSSP -Role Server

在客户端执行以下操作:

set-item wsman:localhost\client\trustedhosts -value *

Enable-WSManCredSSP -Role Client –DelegateComputer *

使用 gpedit.msc在客户端上启用将新鲜凭证委托(delegate)给 WSMAN/*:

展开Local Computer Policy , 展开 Computer Configuration ， 扩张Administrative Templates , 展开 System ，然后单击 Credential Delegation .

在 Settings Pane ，双击 Allow Delegating Fresh Credentials with NTLM-only Server Authentication .

在 Allow Delegating Fresh Credentials with NTLM-only Server Authentication对话框，请执行以下操作:

点击Enabled .

在 Options区，点击Show .

在值中，键入 WSMAN/* ，然后单击 OK .确保Concatenate OS defaults with input above被选中，然后
点击OK .

以下命令现在可以工作(在密码提示之后):

Invoke-Command { dir \\fileserver\devtools } -computer appserver01 -authentication credssp -credential domain\user
