Network shell (Netsh) is a tool an administrator can use to configure and monitor network devices on Windows based computers at a command prompt. A common use of Netsh, is to reset the TCP/IP stack back to default settings.

But not only will Netsh reset the TCP/IP stack, but it can also completely reset your network adapter(s). It will reset the Windows Firewall in Windows 7 too.

Using Netsh in Windows 7

To use Netsh, you will need to open a Command Prompt as an administrator. There are two ways to do this:

• Click the Start button, then All Programs, then Accessories, then right-click Command Prompt, and then click Run as administrator. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

or

• Click the Start button. In the search box, type Command Prompt, and then, in the list of results, right-click Command Prompt, and then click Run as administrator. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

Netsh commands in Windows 7

The following is a list of the Netsh commands you can use to reset your Windows 7 network adapter:

Restores the Windows Firewall with Advanced Security policy to the default policy. The current active policy can be optionally exported to a specified file. This command returns all settings to not configured and deletes all connection security and firewall rules in a Group Policy object.netsh advfirewall reset

Resets the BranchCache service. Flushes the local cache. Every configuration parameter of BranchCache will be reset to its default value.netsh branchcache reset

Resets TCP/IP and related components to a clean state.netsh int ip reset c:\resetlog.txt

Resets IPv6 configuration state.netsh int ipv6 reset

Resets Winsock Catalog to a clean state. All Winsock Layered Service Providers which were previously installed must be reinstalled. This command does not affect Winsock Name Space Provider entries.netsh winsock reset

One of the components of the Internet connection on your computer is a built-in set of instructions called TCP/IP. TCP/IP can sometimes become corrupted. If your connection to the Internet is really slow or you cannot connect to the Internet, and you have tried all other methods to resolve the problem, TCP/IP might be causing it.

Because TCP/IP is a core component of Windows, you cannot remove it. However, you can reset TCP/IP to its original state. If you have any custom settings (default gateway, DNS server, etc.), you will need to set these again manually.

Use a manual method to reset TCP/IP

Note This section is intended for advanced computer users. If you are not comfortable with advanced troubleshooting, ask someone for help. In Windows Vista, a reset command is available in the IP context of the NetShell utility. Follow these steps to use the reset command to reset TCP/IP manually. You will have to restart your system to complete the reset.

1. To open a command prompt, click on the Start button, then All Programs, then Accessories, then click on Command Prompt.


2. At the command prompt, copy and paste (or type) the following command and then press ENTER:

   netsh int ip reset c:\resetlog.txt

   Note: If you do not want to specify a directory path for the log file, use the following command:

   netsh int ip reset resetlog.txt

When you run the reset command, it rewrites two registry keys used by TCP/IP. This has the same result as removing and reinstalling the protocol. The reset command rewrites the following two registry keys:

SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\
SYSTEM\CurrentControlSet\Services\DHCP\Parameters\

To run the manual command successfully, you must specify a file name for the log, in which the actions that netsh takes will be recorded. When you run the manual command, TCP/IP is reset, and the actions taken are recorded in the log file, known as resetlog.txt in this article.

The first example, c:\resetlog.txt, creates a path where the log will reside. The second example, resetlog.txt, creates the log file in the current directory. In either case, if the specified log file already exists, the new log will be appended to the end of the existing file.

Use an automatic method to reset TCP/IP

Revised 10/7/2020. The Microsoft Fix It application to automatically reset the Internet Protocol (TCP/IP) in Windows XP initially referenced in this article is no longer available for download.
