Microsoft has stated that this problem occurs when the dial-up networking entries in the registry get corrupted. The cause of the corruption has not been identified, but it can occur after various actions that have affected Dial-Up Networking. Adding a new network adapter or TCP/IP protocol, or upgrading from one level of operating system to another (e.g. Windows 95 to Windows 98) are situations that could cause this problem.
The 'fix' for this situation requires unloading Dial-Up Networking from the computer. Deleting registry entries related to Dial-Up Networking. Finally re-installing Dial-Up Networking to restore the correct registry information.
1. To begin, remove Dial-Up Networking as follows:
Click Start / Settings / Control Panel / Add/Remove Programs, then select the 'Windows Setup' tab. Highlight the 'Communications' component and click on the 'Details' button. Uncheck the box for 'Dial-Up Networking', then accept all changes by clicking 'OK' wherever appearing. Restart the computer when prompted.
2. After the computer reboots, modify the registry as follows:
Click Start / Run, type in the word regedit, then click OK.
When the registry opens, on the toolbar, select 'Registry', then select 'Export Registry File.'. Save the entire file (Export Range= 'All') to a suitable location (the Desktop is fine). This action backs up the registry into a file that can be restored in case
something goes wrong during this procedure. You can import this registry file back if necessary.
CAUTION: MODIFYING THE REGISTRY CAN CAUSE YOUR COMPUTER TO BECOME INOPERABLE. BE CAREFUL.
Perform the following sequence of steps; click 'YES', if asked, when deleting:
· Click + on HKEY_LOCAL_MACHINE,
· Click + on 'System' below that,
· Click + on 'CurrentControlSet' below that,
· Click + on 'Services' below that,
· Highlight the 'Winsock' folder below, right click the mouse, then select 'Delete',
· Highlight the 'Winsock2' folder below, right click the mouse, then select 'Delete',
· Locate the 'VxD' folder above where the Winsock folders were (still inside 'Services'),
· Click + on 'VxD',
· Highlight the 'AFVXD' folder below, right click the mouse, then select 'Delete',
· Highlight the 'DHCP' folder below, right click the mouse, then select 'Delete',
· Highlight the 'MSTCP' folder below, right click the mouse, then select 'Delete',
· Highlight the 'Winsock2' folder below, right click the mouse, then select 'Delete'.
Exit the registry editor.
3. Re-install Dial-Up Networking as follows:
Click Start / Settings / Control Panel / Add/Remove Programs, then select the 'Windows Setup' tab. Highlight the 'Communications' component and click on the 'Details.' button. Check the box for 'Dial-Up Networking', then accept all changes by clicking 'OK' wherever appearing. Restart the computer when prompted.
Start the Internet browser and display a web page. Everything should work normally.
