13) Kita check koneksinya. Pada windows ubah Settingan TCP/IP Menjadi Seperti ini:IP Address : 172.16.1.2

Subnet Mask : 255.255.255.192

Default Gateway : 172.16.1.62

Preferred DNS Server : 172.16.1.62



14) Setelah settingan diubah, Bukalah Command Prompt computer client dan cek koneksi ke server.C:\Users\antoro>ping 172.16.1.62
