How Windows XP SP2 implements multi-threaded access

        Users who have hit SP2 Windows XP operating system may find that accessing the network is not comfortable. Just open the software that accesses the network in the background. If you open other software that accesses the network or IE browser, you may not be able to open or connect the speed. slow. Especially when the user runs the software of multi-threaded access to the network such as FlashGet, BT or P2P, then any access to the network software will result in frequent access to the network, just like there is no disconnection from the network. Why is this? In SP2, in order to prevent Windows XP SP2 from being spread and attacked by network worms, Microsoft has made the maximum security connection restriction for Windows XP SP2 access network, which causes the download software to fail or the download software takes up all the connections, and the user I can't access the network with other software. Although Microsoft has limited the maximum secure connection limit to 10 threads in Windows XP SP2, this is definitely not enough for the majority of BT enthusiasts and friends who often run multiple network software. I found a software on the Internet that can modify the maximum security connection limit of Windows XP SP2 system file Tcpip.sys, you can download it at http://www.lvllord.de/?url=downloads&lang=en, only 30KB. After downloading, put this file in the system directory, then enter DOS mode, run EvID4226Patch/l=$n$/w=C:\\WINDOWS\\system32\\drivers/l=tcpip.sys, where $n$ is Personal needs to be set, if the author needs to set the maximum security connection limit to 50 threads, then enter EvID4226Patch/l=50/w=C:\\Windows\\system32\\drivers/l=tcpip.sys, I do not recommend This value is changed too high, so the network security will be greatly reduced. I recommend that the average user set to 10 to 30, the BT enthusiast set to 100 to 150, and install anti-virus software and firewall, so that network security is guaranteed.
