我们的一些服务器（W2K8 R2）上周被迁移到云端，一旦完成，我的 powerswhell 脚本开始失败（之前工作正常），在尝试建立连接的行上抛出异常，
$ExSession = New-PSSession –ConfigurationName Microsoft.Exchange –ConnectionUri "http://$g_strExchangeServer/PowerShell" `
-Credential $Credentials –Authentication Kerberos
通过以下消息，
[subd.staging.com] Connecting to remote server failed with the following error message :
**WinRM cannot process the request**. The following error occured while using Kerberos authentication: There are currently no logon servers available to service the logon request.
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 onfig. For more information, see the about_Remote_Troubleshooting Help topic.
+ CategoryInfo : OpenError: (System.Manageme....RemoteRunspace:RemoteRunspace) [], PSRemotingTransportException
+ FullyQualifiedErrorId : PSSessionOpenFailed
仅当我尝试针对我们的测试域时才会发生这种情况，如果我将脚本指向我们的生产域，那么它就可以工作。
已移动到云的所有服务器上都会显示相同的错误。
请注意，所有尚未移动到云的服务器都能够在两个域上运行脚本而没有任何问题。
我尝试了以下方法，但没有运气。
//Add the destination computer to the WinRM TrustedHosts configuration setting.
c:\>WinRM set winrm/config/client @{TrustedHosts="stagingserver"}
//Confirm that WinRM is properly configured.
c:\>Winrm quickconfig
//Make sure that the remote server allows commands from any machine.
PS c:\>Set-item wsman:localhost\client\trustedhosts -value *
使用 Powershell v2 和 WinRM v2
欢迎任何意见。
