   Is it possible to start proceses on remote computer
  Well it is if you have a client application runing on remote machine, but what if I don't want to? Services have networked commands in Windows API, processes dont... Is there a SDK to work with WMI?   
  If you can get access to the server service and access the default shares, and have write access to them there is sufficient space, the remote registry service is running and you have access to service control manager.Then you can transfer an executable file somewhere (maybe make a temporary directory), then remotely install it as a service and start it up.I believe that Systems Internals have something like remote execute which does something similar and then gives you a cmd.exe prompt.In practice this set of requirements means that you must have Administrator privileges.(Plug: I wrote an application called Gencontrol which uses exactly this technique to install VNC for remote desktop access)Mark   ;  Thank you for answer, but unfortunately this way is the one I'm using right now and I'd like to remove that necesity for client service.So far I don't see a way that could be possible... :( Can anyone tell me how WMI stuff works? I have a suspicion that it's multiple service based too... And what about "shutdown -m //remote -s"? Shutdown doesn't seem to invoke service, but it allows shutting remote pc's down...   ;  You could try googling for "rootkit".There are also a number of known exploits through the services running on TCP ports 137 and 138 that will let you run arbitrary programs on a remote computer, at least on an unpatched system.Somehow I think Microsoft would not document an API that allows any system to be pwnxxored, let alone actually provide such an API.  I could be wrong.   ;  The funny thing is that I need to write a program that will monitor servers among other things, so using holes is totally not a good way to go... And that's one more reason I don't want to use client software that someone might want to pawn...Then again Administrative access is pretty free over the domain and if there is a interface for computer managment...Someday I'd like to study those ports too though...
