check window service on all Machine

Question

Hello,

i am using C#.net for application developement.

I wanted to check & list out PCName for one particular window service running across all connected loac/Remote PC.

i tried WMI & but still having problem with credential it gives error for RPC server not available.

same time i could get service infromation using serviceController for remote machine for which user have admin rightes for my machine.

how could i handle all local/remote machine to check that service ? i also require to start that service on user request ??

Thanks
