Before going to the problem, I want to remind you that, do wrap your code snippets around the [code] tags.

To use WMI, windows firewall should be disabled on the remote pc.

I got this output(omitted the entire output)...

-----------------------------------\nWin32_Service instance-----------------------------------Caption: Alerter
Description: Notifies selected users and computers
of administrative alerts. If the service is stopped, programs that use administrative alerts will not receive them. If this service is disabled,
any services that explicitly depend on it will fail to start.
Name: Alerter
PathName: C:\\WINDOWS\\system32\\svchost.exe -k LocalService
State: Running
Status: OK

With firewall enabled, you may receive the following message
The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

@pnalla
Inaddition to WMI you can also look at ServiceControll er Class. You need to specify Machine name and service name for remote pcs..
For WMI to work on remote pcs.. specially for admin tasks, there are certain issues... do check the links posted here
WMI Remote
Also check this implementation on MSDN start stop services

did you try adding:
options.Imperso nation = ImpersonationLe vel.Impersonate ;
just after:
ConnectionOptio ns connection = new ConnectionOptio ns();

?
