在远程计算机上工作时，我偶尔会收到此错误.我在哪台计算机上安装了它.但我能够 ping 计算机并测试连接成功.例如，我今天收到此错误的计算机我昨天可以访问.我知道电脑开着，因为它就在我旁边.

Occasionally I get this error when working on remote computers. It's hit or miss on which computer I get it on. But I am able to ping the computer and test-connection pans out. For example, the computer I got this error on today I was able to get to yesterday. I know the computer is on because It's right next me.

推荐答案

检查 远程过程调用 (RPC) 服务是否正在运行.如果是，那么这是您的工作站和服务器之间的防火墙问题.您可以通过暂时禁用防火墙并重试命令来测试它.

Check to see if the Remote Procedure Call (RPC) service is running. If it is, then it's a firewall issue between your workstation and the server. You can test it by temporary disabling the firewall and retrying the command.

评论后

好的，这是防火墙问题.您必须限制 WMI/RPC 工作的端口，或者在 McAfee 防火墙中打开大量端口.

Ok, it's a firewall issue. You'll have to either limit the ports WMI/RPC work on, or open a lot of ports in the McAfee firewall.

这里有几个网站解释了这一点:

Here are a few sites that explain this:

1. 用于限制端口的 Microsoft KB
2. 迈克菲网站谈论同样的事情
