     An internal error occurred in the Windows Internet Extensions.
     Unable to create a network socket connection.
     Unable to initialize windows sockets interface.
   To remove and reinstall Dial-Up Networking, follow these steps:
   1. Click Start, point to Settings, click Control Panel, and then double-click Add/Remove Programs.
   2. On the Windows Setup tab, click Communications, and then click Details.
   3. Clear the Dial-Up Networking check box, and then click Yes if you receive a message that Dial-Up Networking is required by other components.
   4. Click OK until you are prompted to restart your computer. If you are not prompted to restart your computer, restart it manually.
   5. After Windows restarts, repeat steps a. through d., except select the Dial-Up Networking check box in step c.
4. Click Start, point to Programs, and then click MS-DOS Prompt.
5. Type ping 127.0.0.1 at the prompt, and then press ENTER. If you receive four replies, go to step 6. If you do not receive four replies, remove, reinstall, and then configure TCP/IP.

   To reinstall and configure TCP/IP, follow these steps:
   1. Click Start, point to Settings, click Control Panel, and then double-click Network.
   2. On the Configuration tab, click Add, click Protocol, and then click Add.
   3. In the Manufacturers box, click Microsoft, in the Network Protocols box, and then click TCP/IP.
   4. Click OK two times, and then click Yes when you are prompted to restart your computer. If you are not prompted to restart your computer, do so manually.
      
      Note You may receive "version conflict" error messages. If you receive this error message, click No when you are prompted to keep a newer version of each file.
   5. Repeat step 5.
6. Connect to your ISP, and then start Internet Explorer. Try to visit www.microsoft.com by name and by the Internet Protocol (IP) address. If you can connect by using the IP address but not the fully qualified domain name (FQDN), look for entries in the Hosts file on the local computer. To do this, follow these steps:
   1. Click Start, point to Find, and then click Files or Folders.
   2. In the Named box, type hosts, and then click your hard disk in the Look in box.
   3. If you find the Host file, open the file in Notepad to view the contents. If there are no entries other than the entry for the local host (for example, 127.0.0.1 Localhost), contact your ISP about potential problems with their DNS server.
7. If a Web site does not load when you use either the FQDN or IP address, click Start, point to Programs, click MS-DOS Prompt, and then try to ping a known good Web site by using both the FQDN and IP address.
   
   Note Many larger Web sites have this feature disabled. Therefore, you cannot ping these sites.
   
   If you can ping the site by using the IP address but you still receive the following error message, go to step 8:
   Page can not be displayed
   If you cannot ping the site by using either the FQDN or IP address, verify that you can still ping the local host (127.0.0.1), and verify that the Library Path value in the following registry key is pointing to the correct location for the Rnr20.dll file:
   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\WinSock2\Parameters\NameSpace_Catalog5\Catalog_Entries\000000000001
8. View Network properties for multiple instances of the TCP/IP protocol that are bound to the dial-up adapter.
9. Look for multiple instances of the Winsock files. Rename any file that is not in the appropriate folder unless it is in an AOL folder, C:\Windows\Sysbckup, or C:\Windows\Ws2bakup. The following folders are correct for the Winsock files:
   Winsock.dll in C:\Windows
   Wsock32.dll, Wsock.vxd, Wsock2.vxd, Ws2_32.dll in C:\Windows\System
   The dates and versions of these files should match the version of Windows and the system date for that version, except when Winsock2 or DUN 1.3 have been added to Windows 95. If you find a C:\Windows\Ws2bakup folder, Winsock2 has been installed, and DUN 1.3 is listed in the Add/Remove Programs tool in Control Panel if it is installed.
   
   To rename and replace the Winsock files, follow these steps:
   1. Click Start point to Find, and then click Files or Folders.
   2. In the Named box, type the correct file name (for example, type wsock32.dll, winsock.dll, or wsock.vxd), click your hard disk in the Look in box, and then click Find Now.
   3. To rename extra copies of the files, right-click the file, click Rename, and change the file name extension to .old. For example, rename the Wsock32.dll to Wsock32.old.
      
      Note If you receive an error message that a file by that name already exists, type a different file name extension (for example, .zzz). If you receive an error message that the file cannot be renamed because it is in use, restart the computer to a DOS prompt, and then rename the file from DOS.

10. If your computer is running Microsoft Windows 98 or Windows Millennium Edition, go to step 13. If your computer is running Windows 95, look for the Ws2bakup.bat file on your hard disk. To do this, follow these steps:
    1. Click Start, point to Find, and then click Files or Folders.
    2. In the Named box, type ws2bakup.bat, click your hard disk in the Look in box, and then click Find Now.
    3. If you find the file, go to step 11. If you do not find the file, go to step 13.
11. After you locate the Ws2bakup.bat file, follow these steps:
    1. Click Start, click Run, type c:\windir\ws2bakup\ws2bakup.bat in the Open box, where windir is the folder where you installed Windows, and then press ENTER.
       
       Note If you receive an error message that a sharing violation has occurred, press A to stop running this command. Repeat this step until the batch file has finished running.
    2. Click Start, and then click Shut Down.
    3. Click Restart the Computer in MS-DOS Mode, and then click OK.
    4. At the command prompt, type c:\windir\ws2bakup\ws2bakup.bat, and then press ENTER.
       
       Note If you receive an error message while you are updating the registry, ignore the error message.
12. Type exit to restart Windows.
13. Export and delete the WinSock2 registry keys that are located in the following registry keys.
    
    Note Remove AOL before you follow these steps. Contact AOL for information about how to back up any personal data before you remove the service.
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VXD\AFVXD
    
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VXD\DHCP
    
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VXD\MSTCP
    
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VXD\Winsock
    
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VXD\Winsock2

You receive the error message after you install Internet Connection Sharing with AOL

If you receive the error message after you install Internet Connection Sharing with America Online (AOL), verify that there are no parental restrictions on the account. If you receive the error message after you install Internet Connection Sharing and AOL is your Internet service provider (ISP), verify that TCP/IP (shared) is bound to the AOL adapter and not to the dial-up adapter. By default, if both the dial-up adapter and the AOL adapter are listed in Network Neighborhood when Internet Connection Sharing is installed, TCP/IP (shared) binds to the dial-up adapter. You must remove Internet Connection Sharing and remove the dial-up adapter from Network Neighborhood, and then reinstall Internet Connection Sharing and verify that TCP/IP (shared) is now bound to the AOL adapter. You can then reinstall the dial-up adapter.
