Are you a P2P madman, do you also install the latest SP2 because of the security features of the system? I think, recently, when you use BT software to download those valuable resources, I am afraid that I have encountered a little trouble, your system. Will it be impossible to open a webpage or open a webpage very slowly when doing BT downloads? Since I installed SP2, I have been troubled by this issue. Finally, I had to delete SP2 (no way, the latest blockbuster on BT, it is difficult to give up). By chance, in the article on SP2 features, it was learned that Microsoft had limited the number of TCP concurrent connections in SP2 for security reasons. The root cause is because Service Pack 2 monitors the number of concurrent threads per process in real time, and starts to mask some threads as long as it exceeds the number of security threads it considers. This is to prevent worms such as shock waves, but multi-threaded peer-to-peer tools such as bt and emule are also tied together. .
since found the cause, have to find a way to solve ah. In fact, as early as in various forums, there is a technique for modifying the registry to solve this problem. Find a section of the registry key description in an article in Microsoft's Knowledge Base (Microsoft's original article
http://support.microsoft.com/default.ASPx?kbid=314053
).
HKEY_LOCAL_MacHINE\\SYSTEM\\CurrentControlSet\\Services
TcpNumConnections
Item: Tcpip\\Parameters
Value Type: REG_DWord - Number
is valid Range: 0 - 0xfffffe
Default: 0xfffffe
Description: This parameter limits the maximum number of connections that TCP can open at the same time
唉, is TcpNumConnections not the number of Tcp connections? So I am happy to install SP2 again, and then enter the registry to modify this key. I thought this problem was over. I didn't expect to use BT software again (when I used BC), IE lost his temper and could not open the webpage. It seems that this trick does not work. Just as hesitant to delete SP2 again, BC software authors fixed this problem in BC in the shortest possible time. (Related news:) This temporarily relieved the trouble I encountered. However, the problems of other P2P software have not been solved. It is impossible to wait for the update of these softwares one by one. How should this be good?
When the program asks for the limit value, fill in 100. After the carriage return, the program replaces the modified TCP.SYS file.
due winxp system file protection features, after TCP.SYS the system files are replaced, the System File Protection dialog box came up. Select Cancel, then click Yes to confirm the change. After
reboot the system, full of expectations, while open Bitcomet and IE, peaceful coexistence of days back. Yeah!
The problem is solved! In fact, it is the limitation of the TCP.SYS file. Then, can we save TCP.SYS before the system is upgraded to SP2, and after entering the SP2 patch, enter safe mode or replace TCP.SYS under pure DOS
mode. Can this work work? Leave it to everyone to verify it. I am going to continue to experience the rapid thrill of BT downloads.
Xiao Bian Tip: 1. Before the spread of
modify the registry to lift the skill TCP connection limit has proved to be unworkable
2. This is not SP2 design flaws, but for security reasons restrictive means
3. we do not recommend using this third-party patches, and so the best solution is to upgrade each software.
4. determine users of this patch, please make a backup before using the system, at least a good backup of your files TCP.SYS
