Manually reset TCP/IP

To manually reset TCP/IP, follow these steps:

Hide all

Windows 8 and Windows 8.1

1. On the Start screen, type CMD. In the search results, right-click Command Prompt, and then select Run as administrator.
2. At the command prompt, enter the following command, and then press Enter:
   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.

Windows 7 and Windows Vista

1. To open a command prompt, select Start and then type cmd in the Search programs and files box.
2. Under Programs, right-click the CMD.exe icon, and then select Run as administrator.
3. When the User Account Control box appears, select 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.

Windows XP

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.)

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