窗口一半打开极限固定(补丁)免费下载去除XP、景色和服务器2003年(32和64位) TCP 4226连接企图极限

寻找一项容易的公共事业固定或修补窗口景色tcpip.sys， Windows XP和窗口服务器2003年固定事件ID 4226和打开(不要做极限)一致同时向外去一半打开TCP/IP连接？ 为Windows XP， LvlLord.de写了一个自动化的工具 EventID 4226 Patcher 修补tcpip.sys双，不用用户手册干预。 然而，为窗口景色，用户必须用被修补的版本手工替换原始的tcpip.sys (使用简单 自动patcher批命令剧本或者 正在进行中改变极限的内存驻留的司机)做文丐，直到现在。

窗口一半打开极限固定或补丁是一个应用程序由Dmitry，俄国人写了，镇压、文丐或者补丁系统的tcpip.sys文件，提供TCP/IP通信协议给变动并发的最大数字的主文件一半打开向外去TCP连接，或者连接试图。

以前解释微软在同时一半的数字在Windows XP SP2和所有未来和新版本开始实施上部跳起极限开放外出的TCP连接企图窗口为了减慢病毒传染和恶意节目的传播的率和使能力降低为计算机到发射DDoS或DoS (取消服务)攻击。

在Windows XP SP2和SP3，最大并发一半打开连接企图极限是10， 当窗口景色的极限向范围报告从2 (家庭基本的编辑)时到25 (最后编辑) 并且在窗口景色和其他窗口OS保持同样(10)。 当极限被击中，新的连接企图将被放入队列。 因此，极限也导致缓慢的互联网下载的后果，连接的速度建立了对计算机是限于的外在同辈。 重要极限特别是和对P2P (同辈对同辈)文件分享节目的影响用途例如？洪流、BitComet、eMule、等等和P2PTV例如TVUplayer、PPStream、TVants、PPLive和等。

最明显的症状，当TCP/IP一致连接极限被击中时是一个词条在窗口事件观察者日志：

EventID 4226 ： TCP/IP到达了给一致TCP的数量强加的安全极限连接企图

当它发生(通常，当P2P应用程序跑)，网页将装载极端慢，甚至不可能或装载的出故障。 And inevitable, the BitTorrent (BT), ED2K and P2P-TV channels will be downloading slowly and frequently stopped too (see how to optimize P2P and torrent speed in Vista).

Half-Open Limit Fix patches and fixes the tcpip.sys to unlock, clean and remove this limit, by increasing the maximum limit of half-open connection attempts allowed. The best thing about the Half-Open Limit Fix is that it’s fully automated, and works on all versions of tcpip.sys released so far on both 32-bit (x86) and 64-bit (x64) of Windows XP SP2, Windows XP SP3, Windows Vista, Windows Vista SP1, Windows Server 2003 SP1 and Windows Sever 2003 SP2. Version 3.1 also added support for Windows 7 beta build 6801 (x86,x64).

The current version of Half-Open Limit Fix is version 2.8 version 3.1, and the program Half-open_limit_fix_2.8.zip Half-open_limit_fix_3.1.zip (mirror) can be downloaded from half-open.com (project closed, try TCP-Z instead).

Note: Half-Open Limit Fix 3.1 supports up to Windows 7 Build 6801 only.

To apply the patch using Half-Open Limit Fix, follow these steps:

1. Unpack and extract the ZIP archive to any folder.
2. Run the Half-Open Limit Fix program, i.e. Half-open_limit_fix_2.8.exe or Half-open_limit_fix_3.1.exe (Different version may have different names).
3. Select a new value for the limit for concurrent half-open outbound TCP connections. Valid value range from 1 to 255 (FF).
4. Click on Add to tcpip.sys button.
5. Restart computer.

Note that the patch is not foolproof. Whenever Microsoft releases new version of tcpip.sys, such as in the case of new service pack, the altered tcpip.sys will get replaced back to unpatched version. In this case, user will have to download new version of patched tcpip.sys auto-patcher or new version of Half-Open Limit Fix.

For user that wonders what is the program actually doing in the background, here’s a little clue. The program take ownership and grant full access permissions to administrator on tcpip.sys, and then alter the binary code bytes that represents the connection limit. For Windows Vista, user’s PC will be put into TESTSIGNING mode, with a testing certificate automatically generated and installed with makecert.exe and certmgr.exe, and used to sign the patched tcpip.sys with signtool.exe. This step is required because Windows Vista now require most drivers to be certified and digitally signed. With TESTSIGNING turned on, a “Test Mode” watermark will be displayed on four corner of desktop too. The tool will patch user32.dll.mui to remove the watermark too. Thus, in the case of you suddenly seeing “Test Mode” appearing on your desktop, either re-apply the Half-Open Limit Fix or manually removes the watermark.
