SYMPTOMS
When you dial your Internet Service Provider (ISP), you may connect successfully, but you receive the following error message:

Error 691: The computer you are dialing in to cannot establish a Dial-Up Networking connection. Check your password, and then try again.



CAUSE
This issue can occur for any of the following reasons:
 * You have set up the CompuServe service from the Online Services folder on the Start menu and you have not connected to CompuServe by using the CompuServe software included in Windows 98.

NOTE: The CompuServe setup program does not complete until you connect to CompuServe to set up the default Dial-Up Networking setting.


 * The Telephon.ini file is missing or damaged.


 * Your ISP uses a different file than the Rasapi32.dll file to verify the connection.


 * The Rasapi32.dll file is a different version than the Rasapi32.dll file that is included with Windows 98.



RESOLUTION
To resolve this issue, use each of the following methods. After you use one method, test to confirm if the issue continues to occur.

Create a New Telephon.ini File
To create a new Telephon.ini file, follow these steps:
 * 1) Rename the Telephon.ini file located in the \Windows folder to Telephon.old.
 * 2) Restart the computer.
 * 3) Double-click the Tapiini.exe file located in the \Windows\System folder. Note that the program runs very quickly. The Tapiini.exe file creates a new Telephon.ini file in the \Windows folder.

Connect to CompuServe
To connect to CompuServe by using the CompuServe software included in Windows 98, follow these steps:
 * 1) Click Start, point to Programs, point to Online Services, point to CompuServe, and then click CompuServe 4.0.
 * 2) Click Setup.
 * 3) Type your member name, member ID, and password, and then click OK.
 * 4) Click Internet.
 * 5) Click Yes when you are prompted to use Dial-Up Networking to connect to the Internet.
 * 6) Click the appropriate country, and then click OK.
 * 7) After you connect to CompuServe, log off CompuServe, and then restart your computer.

Verify the Version of Rasapi32.dll
To verify that the current version of Rasapi32.dll is the file included in Windows, check that the value data in the Path value of the following registry key is Rasapi32.dll:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RemoteAccess\Authentication\SMMFiles\PPP
