Repair your faulty TCPIP.SYS driver

Introduction: When I was working on my website, I saw a user from a forum that needs help on his faulty “tcpip.sys” driver. So, I wrote a tutorial for the user to replace his / her bad system files with a genuine file, which is from Microsoft.

For most user, this can be accomplish by using Microsoft recovery console, or, by using the ‘Run’ functions from Windows. To start repairing your faulty driver: “tcpip.sys”, you must have a live copy of Windows XP CD. But, it must be a SP2 or higher for the assigned tutorial.

Replacing ‘TCPIP.SYS’ from Windows.
—————————————————–
1.] Click Start >> Run >> Type: cmd >> Press Enter.
2.] Insert your ‘Windows XP CD’ and type the following commands and directories.

expand D:\i386\tcpip.sy_ C:\WINDOWS\system32\drivers\tcpip.sys

3.] Type ‘Exit’ to close the Command Prompt.

4.] Reboot your computer and start your computer normally.

Replacing ‘TCPIP.SYS’ from Microsoft Recovery Consol.
—————————————————–
1.] Insert your ‘Windows XP CD’ and start Windows. After that, you will need to press ‘F10’ or press ‘R’ to start recovery console.
2.] When you’re inside, the recovery console will prompt you to type in your password.

Notes: by default, the admin password is blank. So, you just hit ‘Enter’ and continue.

3.] Backup your ‘tcpip.sys’ files with this command and press ‘Enter.’

Copy C:\WINDOWS\system32\drivers\tcpip.sys C:\backup\tcpip.old

4.] Type this command and double – check your directory, just before you press Enter.

5.] Type ‘Exit’ and start Windows normally.

6.] Take out your disk and keep it in a safe place.
