WINSOCK2 FIX
=============
If you can't access the Internet with programs like IE, Outlook Express, or other web browsers, you may have corrupted Winsock entries.

To Remove the existing winsock2 registry entries (regardless of the OS) run:

To add Win98 clean entries back in again, run:

To add Windows2000 clean entries back in again, run:

To add WindowsXP clean entries back in again, run:

WINDOWSXP with SP2

There is a new command you can run with SP2 which will reset the Winsock2 registry entries back to their default setting:
netsh winsock reset catalog

TCP/IP RESET
=============
If you need to reset the TCP/IP protocol stack with XP you need to run a small script:

netsh int ip reset [ log_file_name ]

the log_file_name needs to be specified.
e.g. - netsh int ip reset ip_reset.txt
