TCP/IP Has Reached the Security Limit Imposed on the Number of Concurrent TCP Connect Attempts Error on Windows Vista TCP / IP协议已达到了安全限制加诸于大量并行的TCP连接尝试错误的Windows Vista

In Windows Vista Event Viewer, there may be occasional occurrence of Event ID 4226 error which read like this error message: EventID 4226: TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts.在Windows Vista中的事件查看，可能会有偶然发生的事件ID 4226错误，阅读这样的错误讯息： eventid 4226 ： TCP / IP协议已达到了安全限制加诸于大量并行的TCP连接尝试。 The error happens because Windows Vista still limit the concurrent half-open or incomplete (syn packets) TCP/IP connections attempts that able to establish per second.错误发生是因为Windows Vista仍然限制并行半开放或不完整的（的SYN包） TCP / IP连接企图能建立每秒。

The security measure was first introduced in Windows XP Service Pack 2 (SP2) to limit the damage and protect the computer from being used by malicious and dangerous programs such as virus and worms to scan the Internet to infect more systems, or become a Bot that connects to IRC and subsequently accepts commands to launch Distributed Denial Of Service Attacks (DDoS) against other web servers or services.保安措施是首次提出在Windows XP Service Pack 2 （ SP2 ）的限制造成的损害和保护计算机免受正在使用恶意的和危险的程序，如病毒和蠕虫扫描互联网感染更多的系统，或成为一个BOT的表示，连接到体育馆及随后接受命令发动分布式拒绝服务攻击（ DDoS的）对其他Web服务器或服务。

Thus with these concurrect TCP connections limit in place, a lot of programs and applications which launch and trigger lots of outbound and inbound connections at short span of time will hit the limit and cause the error, and in worst cause, cause the connection to be dropped and download or upload speed become slow.因此，与这些concurrect TCP连接限制在地方，有很多的程序和申请的发射和触发大量的外和入站连接，在短短的时间内将达到极限，造成错误，并且在最恶劣的原因，导致连接到被下降和下载或上传速度变得缓慢。 The case is especially true in P2P (peer-to-peer) software such as BitComet, µTorrent, BitTorrent, Azureus, BitSpirit, eMule (eDonkey network), BearShare, Direct Connect, DC++, ApexDC++, ABC.案件，尤其是在P2P （点对点）软件，例如bitcomet ， μ洪流， BT的， azureus ，比特精灵， emule （电驴网络） ，了BearShare ，直接连接，直流+ + ， apexdc + + ，美国广播公司。 The limit may also affect streaming P2PTV such as PPStream, PPLive, TVants, TVKoo!, Sopcast, and etc.限额也可能影响流p2ptv如ppstream ， pplive ， tvants ， tvkoo ！ ， sopcast ，等等。

So in order to download faster, stream faster or speed up web browsing, one possible solution worth trying is by disabling this maximum concurrent half open TCP/IP connection limit.因此，为了下载速度更快，更快地流或加快浏览网页，一个可行的办法值得尝试，是由停用此并行的一半，最高可开启TCP / IP连接的限制。

To crack the TCP limit, the tcpip.sys for Windows Vista has been patched.打击的TCP限制， Tcpip.sys中用于Windows Vista已修补。 You can download the patched tcpip.sys or the AutoPatch (Windows Vista Event ID 4226 Auto Patcher) to turn off Vista TCP connection limit您也可以下载补丁的Tcpip.sys中，或autopatch （ Windows Vista的事件ID 4226自动修补程式）要关闭Vista的TCP连接限制 here这里 , or you can use a simpler ，或者您可以使用一个较简单 GUI based tcpip.sys auto patcher基于GUI的Tcpip.sys中自动修补程式 . 。 For Vista SP1 RC or newer version, check out the为Vista的SP1的钢筋混凝土或更新的版本，请参阅 driver crack司机裂纹 instead.代替。 Instruction guide available too.教学指南提供。 With limit removed, the event ID 4226 won’t appear again too.与限制删除，事件ID 4226将不会再次出现。
