Method 2
=======
The problem may occur if some Incompatible TCP/IP Parameters exist:
1. Click Start, Click Run, type: Regedit
2. Expand the branch until you find the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
3. High-light the Parameters key, you will see data on the right pane:
4. Right-click the following items one by one and select delete in the
dropdown
menu:
¡¤ "Tcp1323Opts"
¡¤ "GlobalMaxTcpWindowSize"
¡¤ "TcpWindowSize"
¡¤ "MTU""
5. Install SP4 again to see if the Internet Connection works normally.
Thank You.
