Network problem Vista

If you facing network connection issue, or more accurately unable to access or connect to Internet or network problem in Windows Vista, Windows 2003 and Windows XP, and repair WinSock settings plus workaround for Vista IE7 strange no connection problem do not save your from Internet woes, you can try to reinstall and reset TCP/IP stack or Internet Protocol, one of the core component of the operating system, which cannot be deinstalled.

Again, with a corrupt TCP/IP stack, the same woes may happen – unable to establish a connection to the server, unable to load a web page, unable to browse and surf the Internet, even though network connection to broadband router or wireless router appear to be OK.

When all means run out, try to reinstall the IP stack with NetShell utility. NetShell utility (netsh) is a command-line scripting interface for the configuring and monitoring of Windows XP, 2003 and Vista networking service.

To reinstall and reset the TCP/IP stack (Internet Protocol) to its original state as same as when the operating system was installed in Windows XP and Windows 2003, simply use the following command in command prompt shell. A log file name must be specified where actions taken by netsh will be recorded on newly created or appended if already existed file..

netsh int ip reset [ log_file_name ]

Example:

netsh int ip reset resetlog.txt

For Windows Vista, things work a little different due to introduction of UAC. Use this guide to perform a reinstalling of TCP/IP protocol in Vista:

  1. Click on Start button.
  2. Type Cmd in the Start Search text box.
  3. Press Ctrl-Shift-Enter keyboard shortcut to run Command Prompt as Administrator.
    Allow elevation request.
  4. Type netsh int ip reset in the Command Prompt shell, and then press the Enter key.
  5. Restart the computer.

The command will remove all user configured settings on TCP/IP stack and return it to original default state by rewriting pertinent registry keys that are used by the Internet Protocol (TCP/IP) stack to achieve the same result as the removal and the reinstallation of the protocol. The registry keys affected are:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\

and

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCP\Parameters\

TCP/IP stack Winsock settings in Windows Vista may get corrupted, causing errors and problems with Internet connectivity. Corrupt Winsock or Windows sockets configuration can be due to a lot of reasons such as installation of a networking software, or due to virus, trojan or malware infection, or sometime even due to disinfection of spyware by security software.

When Winsock corrupts, the networking errors that you may face include unable to surf the Internet with “Page cannot be displayed” error message in Internet Explorer or AOL even though the DSL/ADSL/cable Internet connection is connected. Sometimes, Windows Firewall/Internet Connection Sharing (ICS) service is terminated as well.

To repair and reset the Windows Vista

  1. Click on Start button.
  2. Type cmd in the Start Search text box.
  3. Press Ctrl-Shift-Enter keyboard shortcut to run Command Prompt as Administrator.
    Allow elevation request.
  4. Type netsh winsock reset in the Command Prompt shell, and then press the Enter key.
  5. Restart the computer.

What netsh winsock reset command does are it resets Winsock Catalog to a clean state or default configuration. It removes all Winsock LSP (Layered Service Providers) previously installed, including the potential malfunctioned LSP that causes loss of network packets transmission failure. So all previously-installed LSPs must be reinstalled. This command does not affect Winsock Name Space Provider entries.

Note: To check which LSPs installed on your Vista system, use netsh winsock show catalog command.

It’s also possible to reset TCP/IP Internet Protocol stack .
