The tcpip.sys file is corrupted and the Internet is not resolved.

Recently, I updated the Windows XP SP3 patch. In order to download it freely, I also downloaded the patch to modify the TCP/IP link number limit. After modifying the number of links to 256, I Suddenly I can't get online. This problem has been encountered by Master Dong before, and it has also led to the reinstallation of the system. In fact, the solution is very simple.

Fault performance:

1. After entering the DOS with the CMD command, type ipconfig /all and press Enter to display the following:

Windows IP Configuration

An internal error occurred: The request is not supported.

Please contact Microsoft Product Support Services for further help.Additional information: Unable to query host name.

2. The local connection shows "Connected" but the traffic is zero. The detailed status of the connection is blank;

3. Use the command prompt to type "ping 127.0.0.1" to get the following information:

C:\\Documents and Settings\\Newuser>ping 127.0.0.1 Unable to contact IP driver, error code 2

if Your computer can't access the Internet and the same prompt appears. It may be the same type of fault that I encountered.

Fault analysis:

Unable to access the Internet after modifying the number of connections, it should be caused by this operation. The modification of the connection number patch will modify the tcpip.sys file. Will it be a network failure caused by the file being damaged or lost?

Workaround:

I use flash memory to copy the tcpip.sys file from the C:\\WINDOWS\\system32\\drivers directory on other computers that use the normal operating system. The original C:\\WINDOWS\\system32\\drivers\\tcpip.sys file, and then restart the computer, I can go online again.

Dong Master: The patch that modifies the TCP/IP connection limit does 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.
