Repair Networking in Windows

When dealing with Windows networking issues there are any number of issues that can arise and fixes for those issues, but time and again one of the most reliable resolutions can be to rebuild what we refer to as the network stack. This will not resolve all issues, but if you’ve been working on a particularly stubborn networking issue this is always a safe bet to try.

If you are using Windows XP:

  1. Click on the Start Menu in the lower left of the screen. Then select ‘Run’. In the box that appears type “cmd” and press Enter. *This will provide you with a command line interface from which to apply the fix.*
  2. Type the following: netsh int ip reset c:resetlog.txt then press Enter.
  3. Then type: netsh int ip reset resetlog.txt
  4. Reboot the computer

If you are using Windows 7 or 8:

  1. Click the Start Menu and type “cmd” in the search box.
  2. Right-click the cmd icon that appears and select “Run as Administrator”. *Click Yes if prompted.
  3. Type the following: netsh int ip reset c:resetlog.txt then press Enter.
  4. Then type: netsh int ip reset resetlog.txt
  5. Reboot the computer.

This should reset the TCP/IP stack on your machine.

Fixing the Windows 7 Master Boot Record (MBR)

If you’ve used computers for any length of time you have probably seen your computer fail to boot to Windows once or twice. This will typically be echoed by a message like one of the following:

Error loading operating system

Missing operating system

Invalid partition table

If you are seeing one of these messages there is a very good chance that there is an issue with your Master Boot Record or MBR. The MBR is the section of your hard drive that tells the computer where it can find the Operating System. Sometimes this section can become corrupted and stop functioning correctly. Luckily this is a fairly simple issue to resolve with a little time and patience.

Note** You will need your original Windows install CD for this.

Step 1.

We will need to boot from your Windows Install CD. To do this first insert the disc into the CD/DVD drive, and reboot your computer. You should be met with a prompt asking you to “Press any key to boot from CD or DVD…“. Press any key on the keyboard and this will load up the Windows installer.

Step 2.

You will then be met with the following screen, click “Install Now“.:


Step 3.

You will then see this screen, click “Next“.


Step 4.

Next, click the button for “Use recovery tools” and click “Next“.


Step 5.

From this menu select “Command Prompt“.


Step 6.

From the command prompt you just opened type “D:” to make your CD/DVD drive the working directory. Then change to the boot directory by typing “cd boot“. From the boot directory simply type “bootsect /nt60 SYS /mbr“. 

When you see “Bootcode was successfully updated on all targeted volumes” the process has completed. Type “exit” to return to the previous System Recovery Options screen and click the “Restart” button.

Your computer should now boot to Windows normally.
