Hello!! I want to remotely shut down a pc of which is connected to the same wifi as i! (sorry for my english :p) 
I do the following steps:
1)Open cmd

2)Type net view 

3)Type ping (The Pc I want to gain remote access)

4)Type Shutdown -i and i window comes out!

5)add the "targets" IP (which is copied by ping data)
6)Write a comment, and press ok...
7)And then... ACCESS DENIED (5)

if i do iti to MY PC, it's working!
I saw from some youtube videos, that this is happening because i have no ADMIN access to my network... Is it correct??
If not what is wrong?
If yes, how can i get ADMIN access to my network???
Thanks a lot!!  

turn off "password enable sharing"

try using NET USE command

NET USE \\MyServer\IPC$ mypassword /USER:myuser

or try these, change the following setting at remote computer

4)Type Shutdown -i and i window comes out! 

Were you thinking of the  shutdown.exe -m  option?   Apparently  shutdown.exe -i  means "Display the GUI".  I don't know what I should infer from that.  I will have to test it sometime.   ; )

C:\WINDOWS\system32>shutdown.exe -? | find "/m"
    [/m \\computer][/t xxx][/d [p|u:]xx:yy [/c "comment"]]
    /l         Log off. This cannot be used with /m or /d options.
    /m \\computer Specify the target computer.
