Adding a new node on the local machine gives a “Failed to get the service status” error. The log file displays the following error: "Connecting to remote server <SERVER NAME> failed with the following error message : The WSMan service could not launch a host process to process the given request. Make sure the WSMan provider host server and proxy are properly registered."
The cause of this issue is due to the Windows User Account Control (UAC). The remote account must be a domain account and a member of the remote computer Administrators group. If the account is a local computer member of the Administrators group, then UAC does not allow access to the WinRM service. This error happens even if the account is a Local Administrator and the command line is run with administrator privileges.
To solve the problem, UAC filtering for local accounts must be disabled by creating the following DWORD registry entry and setting its value to 1:
[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System] LocalAccountTokenFilterPolicy
