Notes
Sometimes there's connection in workplace and then sometimes there's a disturbing about network so i came to solve it with my own knowledge and experience. perhaps me always seek for judgement for others.
i try everytime to solve about network but now alhamdulillah finnaly i found the source of problems, and i change the dns in the dhcp server so every client/user can obtain the ip and the dns. problem solved so now is free time i try to learning about it support,. i dont know how everytime i tried always small issue.
