After updating to Ps 4.0, I found some windows hosts are encountering the following errors when I run Invoke-Command to check the powershell version. See Fig-1.
Connecting to remote server X.X.X.X failed with the following error message : The WS-Management service cannot process the request. Cannot find the Microsoft.PowerShell session configuration in the WSMan: drive on the X.X.X.X computer.
