In addition to the connection problem, when you release and renew the IP address, you receive:

An error occurred while renewing interface 'Internet': An operation was attempted on something that is not a socket.

This behavior is the result of a damaged WinSocks library or TCP/IP stack.

To resolve this issue:

01. Copy / Paste the following to a WinSock.bat file:

@echo off
REM Export the WinSock and WinSock2 keys in case you wish to restore them.
regedit /a winsock.reg "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock"
regedit /a winsock2.reg "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2"
@echo REGEDIT4>WinSockDel.reg
@echo.>>WinSockDel.reg
@echo \[-HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock\]>>WinSockDel.reg
@echo.>>WinSockDel.reg
@echo \[-HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2\]>>WinSockDel.reg
@echo.>>WinSockDel.reg
regedit /s WinSockDel.reg
del /q WinSockDel.reg

02. Open a CMD prompt.

03. Type WinSock.bat and press Enter.

04. Reset TCP/IP to its' installed state.

05. Restart Windows XP.

06. Check / verify the TCP/IP settings.

07. Connect to the internet.
