How to Replace Winsock in Windows XP

1. Open a command prompt by clicking on 'Start,' and then 'Run.' In the dialog that pops up, type in 'cmd,' and press 'Enter.'
2. Reset your Winsock entries to their defaults by typing in 'netsh winsock reset catalog' at the command prompt, and then press 'Enter.' Reset the TCP/IP (Transmission Control Protocol/Internet Protocol) stack by typing in 'netsh int ip reset reset.log,' and press 'Enter.'
3. Reboot your computer. If the Internet still does not work, the problem is not Winsock.
