Access denied when running Get-WmiObject -Class Win32_SystemServices -ComputerName ServerName

Question

When I run the following powershell WMI command 
Get-WmiObject -Class Win32_SystemServices -ComputerName SRV_XYZ
I get the following error:
Get-WmiObject : Access denied
At line:1 char:14
+ Get-WmiObject <<<<  -Class Win32_SystemServices -ComputerName SRV_XYZ
    + CategoryInfo          : InvalidOperation: (:) [Get-WmiObject], Managemen
   tException
    + FullyQualifiedErrorId : GetWMIManagementException,Microsoft.PowerShell.C
   ommands.GetWmiObjectCommand
Note that, using the same user I run the previous command, I also run the following command, but this completes successfully with no errors:
Get-WMIObject -query "select * from Win32_ComputerSystem" -computername SRV_XYZ
Note also that SRV_XYZ is a remote server.
The Question is: what additional permission I should give the current user on that SRV_XYZ remote server to be able to run the first WMI command remotely and successfully?

Answer 1

Still accesee denied ! ... I tried to chnage win32_systemservices to win32_service but it gave me the same error.
Regardless of whither it is a usable class or not! my question is related to authentication and permission that needed to be granted to the current user to be able to remotely run Win32_SystemServices or Win32_service.
Note that running any of the commands with domain admin rights completes successfully.
