Windows 在多台服务器上安装KB修补程序

我试图在多台服务器上安装KB修补程序，但在执行时收到下面的错误消息。有人能帮我吗

仅供参考：系统上已启用PSRemoting

代码：

$SB={ Start-Process -FilePath 'wusa.exe' -ArgumentList "C:\Program Files (x86)\McAfee\Win7AndW2K8R2-KB3134760-x64.msu /quiet /norestart" -Wait -PassThru }


Invoke-Command -ComputerName computer -ScriptBlock $SB

错误：

[computer] Connecting to remote server computer failed with the following error message : WinRM cannot process the
request. The following error occurred while using Kerberos authentication: Cannot find the computer computer. Verify
that the computer exists on the network and that the name provided is spelled correctly. For more information, see the

看起来您正在尝试在工作组计算机上运行脚本，如果我说的对，那么在工作组计算机上运行脚本时，在运行脚本之前，必须在每个服务器上设置以下命令

Enable-PSRemoting -Force
Set-Item wsman:\localhost\client\trustedhosts *
Restart-Service WinRM
Test-WsMan <server name>

启用PSRemoting-强制
设置项目wsman:\localhost\client\trustedhosts*
重新启动服务WinRM
测试WsMan

目标计算机是否与发送请求的计算机位于同一域中？如果没有，则不能使用Kerberos身份验证。您应该查看错误建议的帮助主题，并确保所有设置都正常（仅启用远程处理并不总是足够）。该服务器是域的一部分吗？服务器位于同一域中。但我仍然面临着这个问题。
