Ok is very simple. Create a windows app and make 2 buttons.

button1 will be start
button 2 will be stop

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Shell("Net STOP DHCP")
End Sub


Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Shell("NET START DHCP")
End Sub


add hotkeys if you want
