Remove delay in LAN games under Windows 7

I find it weird when last time playing Warcraft III LAN game with my housemate, we both feel a bit of delay on the client side (joining one). After doing some search on web, we found that by modifying a bit of registry, the strange delay was removed. This only happens under Windows 7.

1. Open up Registry Editor, navigate to HKLM\SYSTEM\CurrentControlSet\services\Tcpip\Parameters\Interfaces\
2. Look for a subkey name similar to this: {E3CF3EE3-AE61-4A50-8121-2A6CF502EF0F}
3. Inside the subkey, there is a value DhcpIPAddress, check if it is the IP Address given by your router. If so, add 2 new DWORD (32-bit) keys with value as follows:
     TcpAskFrequency    1
     TCPNoDelay    1
4. Restart your PC.
