I had the same problem when trying to run a PowerShell script that only looked at a remote server to read the size of a hard disk   I turned off the Firewall  Domain networks  Private networks  and Guest or public network  on the remote server and the script worked   I then turned the Firewall for Domain networks back on  and it worked   I then turned the Firewall for Private network back on  and it also worked   I then turned the Firewall for Guest or public networks  and it also worked

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
