Question

I am not asking how to code it

Process.Start("shutdown","/s /t 0"); 

I am asking if
I made a user interface to detect the computers in the network. Knowing their ip and having domain admin priveledges. How do I send a signal to execute my c# .exe ?

Answer 1

The command line is

shutdown /m \\<MACHINE NAME OR IP>

so you can use:

Process.Start("shutdown",string.Format(@"/s /t 0 /m \\{0}",machineIp));
