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.

UPDATE
It might be due to various issues.I cant say which one is there in your case. It may be because:

For DCOM settings refer to registry key HKLM\Software\Microsoft\OLE, value EnableDCOM. The value should be set to 'Y'.
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.
My problem turned out to be blank spaces in the txt file that I was using to feed the WMI Powershell script.
