我正在尝试测试 winrm 是否适用于系统列表；但是，当我尝试连接到系统时，我似乎无法捕捉/消除出现的错误。它似乎适用于一个系统：

PS C:\Users\Egr> winrm id -r:system1
IdentifyResponse
    ProtocolVersion = http://schemas.dmtf.org/wbem/wsman/1/wsman.xsd
    ProductVendor = Microsoft Corporation
    ProductVersion = OS: x.x.xxxx SP: x.x Stack: x.x

但不适用于另一个：

PS C:\Users\Egr> winrm id -r:system2
WSManFault
    Message = WinRM cannot process the request. The following error occured while using Kerberos authentication: The net
work path was not found.
 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.

Error number:  -2147024843 0x80070035
The network path was not found.

我已经尝试将它包围在一个 try/catch 块中，但它似乎并没有让它静音。我正在尝试对这些系统进行检查，以确定哪些系统正确配置了 WinRM 并正常工作；但是如果脚本一直输出这个文本，它就不会很好地工作。有什么方法可以抑制这个文本，还是有更好的方法来测试 WinRM 连接？

您可以将错误流重定向到$null并评估$LastExitCode以检测错误：

$rhost = 'system2'

winrm id -r:$rhost 2>$null
if ($LastExitCode -eq 0) {
  Write-Host "$rhost OK" -ForegroundColor green
} else {
  Write-Host "$rhost unavailable" -ForegroundColor red
}
