Summary
You can try to reset TCP/IP if you have Internet connection issues. This article describes two ways to reset TCP/IP. To have us reset TCP/IP for you, go to the "Here's an easy fix" section. If you prefer to reset TCP/IP manually, go to the "Let me fix it myself" section.

Here's an easy fix

To reset TCP/IP automatically, click the Download button. In the File Download dialog box, click Run or Open, and then follow the steps in the easy fix wizard.
  • This wizard may be in English only. However, the automatic fix also works for other language versions of Windows.
  • If you’re not on the computer that has the problem, save the easy fix solution to a flash drive or a CD, and then run it on the computer that has the problem.
For Windows 8.1, Windows 8, Windows RT, Windows 7, Windows Server 2012R2, Windows Server 2012, Windows Server 2008 R2


For Windows Vista, Windows XP, Windows Server 2008 or Windows Server 2003

Let me fix it myself

To manually reset TCP/IP, follow these steps:

Note You must be logged on to the computer as an administrator to perform the steps.

For Windows 8 and Windows 8.1
  1. On the Start screen, type CMD. In the search results, right-click Command Prompt, and then click Run as administrator.
  2. At the command prompt, enter the following command, and then press Enter:
    netsh int ip reset c:\resetlog.txt
    Note If you don't want to specify a directory path for the log file, run the following command instead:
    netsh int ip reset 
  3. Restart the computer.
For Windows 7 and Windows Vista

  1. To open a command prompt, click Start and then type cmd in the Search programs and files box.
  2. Under Programs, right-click the CMD.exe icon, and then click Run as administrator.
  3. When the User Account Control box appears, click Yes.
  4. At the command prompt, enter the following command, and then press Enter:
    netsh int ip reset c:\resetlog.txt
    Note If you don't want to specify a directory path for the log file, run the following command instead:
    netsh int ip reset resetlog.txt
  5. Restart the computer.
For Windows XP
  1. To open a command prompt, click Start, and then click Run. In the Open box, enter the following command, and then press ENTER:
    cmd
  2. At the command prompt, enter the following command, and then press Enter:
    netsh int ip reset c:\resetlog.txt
    Note If you don't want to specify a directory path for the log file, run the following command instead:
    netsh int ip reset resetlog.txt
  3. Restart the computer.

When you run the reset command, it overwrites the following registry keys, both of which are used by TCP/IP:
SYSTEM\CurrentControlSet\Services\Tcpip\Parameters SYSTEM\CurrentControlSet\Services\DHCP\Parameters
This has the same effect as removing and reinstalling TCP/IP. To run the manual command successfully, you must specify a name for the log file in which the netsh actions will be recorded. (This log file is referred to as "resetlog.txt" in the manual procedures earlier in this section.)

Sample log file for NETSH INT IP RESET

The following is a sample of the log file that is generated by netsh when an IP reset command is issued. The actual log file might vary, depending on the configuration of the computer. When the TCP/IP registry keys have not been altered from their original configuration, there might be no actions logged in the file.
