Increase Vista TCP/IP Max Connections

This post is obsolete. You should check out the new updated post:
Bypass Windows TCP/IP Limit
As you may have noticed Microsoft still limits your half-open (incomplete/syn packets) connection attempts per second that the system can make. Microsoft has done this since Windows XP Service Pack 2 to keep your computer from being used by dangerous programs such as worms that scan the internet to infect more systems and to keep your computer from being a host of a Bot that connects to IRC that accepts commands to launch Distributed Denial Of Service Attacks (DDoS) against other people and companies they do not like.
Unfortunately for us and companies, this limit effects our internet by limiting the capability of P2P (Peer 2 Peer) applications like µTorrent, BitTorrent, BitComet, Azureus, BitSpirit, eMule (eDonkey network), BearShare, Direct Connect, DC++, ApexDC++, or even P2PTV such as PPLive, PPStream, Sopcast, TVAnts, Peer to Peer, Web server, FTP, and many other applications we love to use but cannot take full advantage of. Basically, you will make uTorrent faster as well as all these other apps you need.
When the limit is hit, You will recieve a Notice in Event Viewer Saying:
EventID 4226: TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts.
This means Vista Has maxed out our connect attempts.
[NEW] vistatcpipuacpatch21 EventID4226Fix for Windows Vista v2.1 for SP1 (build 18000) (32/64bit)
Installation Instructions:
Extract the archive to a directory on your computer.
Windows Vista SP1 32 bit: InstallPatch32.bat
Windows Vista SP1 64 bit: InstallPatch64.bat
Uninstallation: UndoPatch.batPlease Note! Due to Vista SP1 restriction of using signed drivers only:
Vista SP1 (32/64) requires all drivers to be digitally signed. to bypass this limitation, we use a tool called ReadyDriver Plus v1.1. after install it will bypass the blue-screen and will boot Vista normally.For those of you who wants to do it manually:
To use this driver you must press F8 at every Windows boot load. Then, in the boot menu, choose the option to disable driver signature. Vista will now boot successfuly.

Turn off Driver Signing in Vista 64-bit | Kamikaze
May 15th, 2008 on 2:56 am[...] One of the security features (PAINS) you see in Vista 64-bit is the driver signing feature. This makes it almost impossible to replace most of the systems files with modified files. Most commonly if you want to patch your TCP/IP Max Connection Limit . [...]

@rovassy
Which patch are u using?
@lec1
Im assuming you installed the patch vistatcpipuacpatch21.rar.
The error you might have gotten wud be that readydriver plus exe file was not found in the directory where u ran the patch from. This is not a problem as u can install readydriver plus seperately.
Soooo..
1st step: run the patch file…
2nd step: install ready driver plus… (if you have only windows installed on your system then jus leave the default installation settings and click next next next.. finish..)
thats what you did? Then you shud be in the green… you can check your event viewer to check if you are getting any EVENTID 4226 Errors..

@aadu first: thank you so much for your support i appreciate that.
ok i have installed this patch: vistatcpipuacpatch19c and i got something like this:
Windows Vista Concurrent TCP/IP Connection Attempt Limit Auto Patcher

Version 1.9c
Auto Patcher batch script
for 32-bit version of Windows Vista

Ok.

ERROR: Error opening the file. There may be a disk or file system error.
*** Patch installation is complete. Please RESTART computer!!
Press any key to continue . . .
then i installed the ReadyDriver Plus v1.1
when i start the computer i see it is working.
and i did this too: click on run type REGEDIT and click OK.Now navigate to : [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters]
“TcpNumConnections”=dword:00011170 and edit this value to whatever amount of connections you need.
and install this one too : Vista_TCPIP_limit_16777214
then i checked the the event 4226 like this : Start > Control Panel > Administrative Tools > Event Viewer > System… Look for event 4226 (sort by event)
and i saw i still get the event 4226.
now the question is :
what you think i should i do now?
thanks in advance

after that i ran UndoPatch.bat and now i see i have the 2 icons in the drivers directory the tcp/ip original and the tcp/ip .sys

@lec1
The two files u see are the backup of your original TCP/IP.SYS and the current one in use.
Try booting in safe mode before installing the patch. And run the patch from an elevated cmd prompt. (right click on the batch file and click Run as Administrator)
You shud uninstall readydriver plus since your not running SP1.

Hi. I have installed 2.2 patch (32bit) in my Vista ultimate 32-bit SP1 but I have to press f8 and disable driver signing each time. I insalled Readydriverplus 1.1, all by default, when I restart I see 3 entries (I have Windows XP too) Older version of windows, Windows vista and readydriver plus. When I select vista, the same error as above appears, when I select readydriver plus it says an error of boot.bin, so Readydriver plus didn’t solve me the problem.
Any solutions?? (sorry for my english.. i’m spanish).
July 24th, 2008 on 8:13 pm

@smokii
I have vista 64bit SP1 myself and have been using the patch vistatcpipuacpatch21.rar for a very long time now without any problems.
Did you follow the instructions correctly? You need to install ready driver plus to automatically bypass driver signing. Otherwize it will give blue screen.
November 2nd, 2008 on 3:12 pm
Hi,
So I ran the batch file and have the new version of tcpip.sys, I hit F8 at boot to disable the dricer signature enforcement, but when I hit enter here it just goes straight to the windows failed to start. a recent harware or software change might be the cause. The driver just continues to not load. Any help???
December 25th, 2008 on 1:19 pm
My problem is with ready driver plus and it’s giving me the headache for me a long time. I’ve ran InstallPatch32-18063 batch file, it went perfect then it installed ready driver plus and I didn’t changed anything there same folder, 1 stroke and all the options are checked so I expected no errors. But when I rebooted it selected ready driver plus ok. however when it reached advanced boot options it selected Safe Mode instead of forced disabled-signiture boot all by itself and then windows started loading system files for the prep of safe mode. After some repetition I gave up and uninstalled evrything. Any suggestions???
