Apparently in Windows Vista, Microsoft still enforce and hard-limit (hard coded in tcpip.sys) the maximum simultaneous half-open (incomplete) outbound TCP connection attempts per second that the system can make, as in Windows XP SP2, in order to protect the system from being used by malicious programs, such as viruses and worms, to spread to uninfected computers, or to launch distributed denial of service attack (DDoS). When the limit is hit, in Event Viewer, there will be such an entry: EventID 4226: TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts Unless Windows XP SP2 which has 10 maximum incomplete concurrent connection attempts limit per second, Windows Vista default limit is based on which edition of Vista users are using. For example, Home Basic has maximum limit of 2, and Vista Ultimate is 25 per second. Normal Windows Vista users should not face any problem or slow network connection with the half-open connections limit. However, heavy P2P (peer-to-peer) applications users such as uTorrent, BitTorrent, BitComet, Azureus, ABC, eMule (eDonkey network), etc, or P2PTV such as TVants, PPLive, PPStream, Sopcast, etc may face some error or slow download and upload speed due to this limit. It Works for both 32 and 64 bit version of Vista Plz Seed after Download Plz Wait if no seeds It Does the following --------------------- Due to enhanced security, to fix or crack the TCP concurrent connection limit in Vista is not as easy as in Windows XP. To remove maximum concurrent half-open connection limits in Windows Vista, apply the patched tcpip.sys with the following steps: Download patched tcpip.sys: Vista TCP/IP and UAC Auto Patcher (patched tcpip.sys is contained inside the archive) 64-bit tcpip.sys or 32-bit tcpip.sys. Alternative download link for 32-bit and 64-bit. Open command prompt, and run the following 2 commands: 1. takeown /f c:windowssystem32driverstcpip.sys 2. cacls c:windowssystem32driverstcpip.sys /G “usernameâ€:F Replace username with the actual user name that used to log on to Windows Vista currently. The second command can also used improved lcacls: icacls c:WindowsSystem32driverstcpip.sys /grant “usernameâ€:f Disable the TCP/IP Auto-Tuning feature by running the following command in command prompt: netsh int tcp set global autotuninglevel=disable For 64-bit Windows Vista (x64), the integrity checks need to be disabled as it need all drivers to be signed. So run the following command in DOS prompt: bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS Note: Above command no longer supported, and users require to press F8 on system startup to bypass driver signing integrity check. Replace the tcpip.sys in C:windowssystem32drivers folder with the patched tcpip.sys downloaded from step 1 (remember the use the correct x64 or x86 version). Normally, this procedure can be done by simply login to Windows Vista with administrator account. However, if the process failed, reboot the computer and then press F8 to boot up in Safe Mode, and then copy and paste overwrite the tcpip.sys. Next, the maximum number of TCP half complete connection limits need to be set in registry. Open registry editor (regedit), and navigate to the following registry key: HKEY_LOCALL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters Right click on the right pane, select “Newâ€, then select “DWORD valueâ€. Enter the new value name as “TcpNumConnections†(without quotes). Double click on TcpNumConnections registry value, and modify the value data to the desired maximum TCP/IP connection limit that you want to allow, in decimal value. For example, enter 500 as the value data for TcpNumConnections. You can use any limit that you prefer. Alternatively, download this registry registration file (another download link) that when executed, will set the TCP simultaneous connection limit to 16777214 (you can always modify the value in the file or in the registry after applied). Restart computer. New: Windows Vista Event ID 4226 Auto Patcher Windows Vista Event ID 4226 Auto Patcher has been renamed as Vista tcpip.sys and UAC Auto Patcher, which now has more than 6 versions of auto patcher download links for different versions of tcpip.sys with the release of various hotfixes and SP1. Visit here for details. New: Half-Open Limit Fix (Automated tcpip.sys Patch using Test Self-Signed Certificate) Also Available - Driver Version: CrackTcpip.sys for Vista SP1 v.668 - a non-patching method to bypass TCP connection limit. Also available is TCP/IP auto patcher for 64-bit (x64) Windows Vista SP1. Gui Version: VistaTcpPath TCP Auto Patcher which works for Vista RTM (non-SP1) version of tcpip.sys. Old Version: Version 1.0 Version 1.2 Version 1.3 Version 1.4 Version 1.5 With thanks to YaronMaor for batch script. The TCP connection limit which trigger Event ID 4226 has now increased to 500 (or any other value you set), and will likely fix the error for re-occurring again.
Plz Wait if No Seeds
I Will Seed it When i am free

Does this work for real and is it stable?
I just tried this patch. It changed the settings alright. Upon re-boot windows detected the change and wouldn't boot. Even gave the 'ole blue screen (haven't seen that one for a few years) and made me boot with the install disc to fix what it called an error.
So... either this is bullshit or some instuctions are needed.

This is a collection of bat, sys and reg files. You're a braver man than me if you ran this on your PC!!
Bro Install Carefully

Dont use *.reg files
Just use installpatch xx.bat
Just use installpatch xx.bat
Error came after using JUST the bat install.
yup, I'm brave. All I do is change OS's. About once every 2-3 weeks or so. I don't keep anything worth a dam on this partition. ;)

No Other Complaints Only u haa !
Ok, does anyone know any patch to get more halfopen ports in XP with SP3? Or how to increase halfopen ports with SP3?
get the patcher on http://half-open.com/ to solve all your TCP_IP half-open connection limitations... Works on ALL windows versions.
Seeds r lessing Down
Plz Seed It guys

Most of these changes have little effect and some can even potentially slow down your connection. The TCP/IP Auto-Tuning feature introduced in Windows Vista is much better at optimizing broandband connections than the simple system in place in Windows XP. The reason why the maximum simultaneous connections in Windows Vista remains the same, simply is because there is rarely any need for a higher number. Sure, changing it does not hurt but I would definately avoid a solution that involves modifying system files, making a bunch of changes in the Windows registry and then disabling important Windows features.
Oh, I forgot to also mention that reverting many of the changes will probably not be possible. If you would for example use your computer to seed a hundred torrents then this will help. By the way, I have not tested this torrent and do not therefore also know if it contains any viruses!
