Solution
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.
Edit after comment:
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.
Here are a few sites that explain this:
- Microsoft KB for limiting ports
- McAfee site talking about the same thing
Problem
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. ``` Get-WmiObject : The RPC server is unavailable.
