How to fix WinXP corrupted tcpip.sys file

Many friends' WinXP system, after installing the latest SP3 patch, found that the Internet speed was slower, so the patch of TCP/IP connection limit was modified. As a result, even the network could not go up. In the case of this situation, the first thing that people think of is still reinstalling the system, but in fact, there is no need to be so troublesome. We can check the system first and then find out the cause of the problem, and then it is easy to solve.

Solution:

Using flash memory from other normal use In the computer that is consistent with the operating system of the machine, copy the tcpip.sys file in the C:WINDOWSsystem32drivers directory to replace the original C:WINDOWSsystem32driverstcpip.sys file, and then restart the computer, and you can go online.

Summary: Patches that modify the TCP/IP connection limit do modify the tcpip.sys file. Most patches will back up the original tcpip.sys file to the same directory before modifying the operation. If the modification fails, just find the backup file (such as tcpip.sys.bak) and restore it.
