Error 691: Access denied because username and/or password is invalid on the domain.
Potrebno je provjeriti korisničke podatke, tj. korisničko ime/username i lozinku/password.

Error 718: PPP Timeout.
Provjerite Vaše korisničko ime i lozinku. Korisničko ime bi trebalo biti u obliku korisničko ime@iskon-dsl i zapisano malim slovima. Sve lozinke su osjetljive na velika i mala slova pa pazite kako ih unosite i pripazite da Caps Lock tipka na tipkovnici nije slučajno pritisnuta.

Error 718: može značiti da je došlo do fizičkog problema sa vezom (uređaj ili kabel).
Ako koristite Windows 2000 i WinPPPoE softver, provjerite da niti jedan protokol nije povezan sa TCP/IP protokolom koji koristi DSL usluga. Pokušajte ukloniti WinPPPoE protokol i ponovno kreirati konekciju pomoću "Network and Dial-up Connections" koristeći ispravne podatke za spajanje.

The TCP/IP stack is a collection of protocols that allow your computer to communicate with other computers. It's the protocol used by the Internet and the protocol most often used in local area networks. If your TCP/IP stack is corrupt, you may be unable to use other resources on your network or the Internet. Reinstalling TCP/IP is the easiest way to fix this.
Difficulty: Moderate
Instructions
Things You'll Need:

* Windows XP installation files (on disk or hard drive)

1.
Step 1

Click your "Start" button. Click "Run." Type "cmd" without the quotes. Click "OK." A command prompt will open.
2.
Step 2

Type the following: netsh int ip reset resetlog.txt. Press "Enter." Once the process is complete, restart your computer. Test to see if you still experience a problem.
3.
Step 3

Run a repair of your Windows XP installation if you're still having difficulties. This will reinstall TCP/IP as part of the repair process. You will need your Windows XP installation files, either on CD or on your hard drive.
4.
Step 4

Insert your Windows XP CD or double-click "setup.exe" in the directory on your hard drive. On-screen instructions will guide you through the process. Be sure to choose to repair your existing installation, rather than creating a new installation. The repair process looks much like the normal Windows XP installation process and will probably take 15 to 40 minutes, depending on the speed of your computer.
5.
Step 5

Write down your Windows XP product key. The product key should be on the COA sticker on the front, side or bottom of your computer. When the repair process prompts you, enter the product key. Choose to keep all your existing settings for computer and workgroup or domain names. At the end of the repair process, the computer will start Windows.
