What The Errors Mean

Windows 98 Error Codes

* Dial-Up Networking: Error 602 The modem is being used by another Dial-Up Networking connection.

If there are multiple modems set up on the computer make sure the dialer is looking at the correct modem. Check for any fax software or any other software that might be trying to use the modem. You may need to look in the start menu programs to see what is being loaded on startup; and close anything that might be holding the modem open. You can also restart the computer and hold down the control key when you see the text that says Starting Windows 98. Doing a Ctrl, Alt, Delete and ending task on everything except Explorer and Systray should release the modem too.

* Dial-Up Networking: Error 629 You have been disconnected from the computer you have dialed.

There are several reasons why a customer could receive this error message. Be sure to verify that they are using the correct username and password. Check to see what phone number they are dialing and make sure it isn't set to use area code and dialing properties. You should also verify TCP/IP settings. Have the customer take out the password and try to connect without it; if they aren't prompted for password delete TCP/IP and reinstall. It might also be necessary to remove and reinstall Dial-Up Networking.

* Dial-Up Networking: Error 630 The computer is not receiving a response from the modem.

Verify that the dialer is looking at the correct modem. If the modem is internal, restart the computer and see if the modem will respond. If the modem is external; turn the modem off and then back on. You may want to check if they have an init string entered in the extra settings box. If so, take out the string and restart the computer. As a last resort go into modem control panel, click the diagnostic tab, click the port corresponding with the modem and click more info. If you don't receive a response it may be necessary to remove and reinstall the modem. Use your best judgement when working with a customers modem and make sure they have any needed software before doing so.

* Dial-Up Networking: Error 635 Cannot establish the Dial-Up Networking session.

Go to My Computer, Dial-Up Networking and go the properties of the MCN icon. Click the Server Type tab and verify settings. Be sure that Enable software compression and TCP/IP are the only ones selected. Click the TCP/IP settings button and verify settings there. Click OK to save changes.

* Dial-Up Networking: Error 676 The line is busy.

There are a couple reasons a customer may get this error message. The first could be that the number is actually busy. Check the portmaster they are dialing or try dialing the access number yourself. If the number isn't busy you should check their settings. Double check that the number they are dialing is the correct one for their area. You may also want to see if the customer needs to dial a prefix to get an outside line.

* Dial-Up Networking: Error 691 or 718 The computer you are dialing cannot negotiate a dial-up networking connection.

Verify that the customer is using the correct username and password. You may also want to go to My Computer, Dial-Up Networking, and the properties of MCN. Click on the server type tab and make sure that log onto network isn't checked.

Go to My Computer, Dial-Up Networking and the properties of the MCN icon. Click on the server type tab and click on the TCP/IP settings button. Verify the TCP/IP settings and click ok. You will also want to verify that both Dial Up Adapter and TCP/IP are installed in the network control panel. After verifying that the components are installed you will need to verify the settings and click ok.
