I tried editing .ini file, it prompts access in denied. And if i try to chnage using command prompt that also it does no allow me to do so.I cannot even use "Show Max_allowed_pac kets". It says show is not recognized as internal and external command.

Code:

# *** DO NOT EDIT THIS FILE. It's a template
