Hey guys, the code works!!!
Sorry JStewart, it was my problem.... Last time after I type that code and I left cmd at once.... Today I entered the code again, it shows "this code need to run by administrator only"... which means last time i did not enter it properly.... and TODAY i run it as an admin, this i restart my computer.... and YESSSSSSSS i can launch dayz and find those servers!!!!!!
BIG thanks again to JStewart for your reply!
