Fix for concurrent TCP connection limit in XP SP2

[Mictlantecuhtli]

Apparently the registry value I replied to another thread doesn't work anymore in SP2 (what else is new), but here seems to be a solution for this:

http://www.lvllord.de/4226fix/4226fix.htm

What's this all for?
After almost everybody knows the <<EventID 4226: TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts>>, I used a day to create for educational purpose a fix for this argumentative feature.

Unfortunately there exists no REG-key which could easily be set (would be so nice and easy, right? *smile*). The file TCPIP.SYS in the directory C:\WINDOWS\SYSTEM32\DRIVERS and C:\WINDOWS\SERVICEPACKFILES\I386 has to be changed (system dependend eventually in C:\WINDOWS\SYSTEM32\DLLCACHE, too).

Needed things:
- Windows XP SP2 (from RC2 upwards) or Windows 2003 Server SP1 beta
- patcher (2.10a
- a small amount of time

What's been done:
To say it easy: the before 10 half-open connections are beeing increased to 50 (which should be enough for heavy users and should be save enough agains worm spreading) and the CRC is been corrected. And that's it! What exactly is changed (for build 2092-2180), can be read in the howto.

Comment:
The method described here, should only be used by users, who know how to handle all the described. With the download of the here published program the user know, that changes are made on third party files. For damages in every kind I cannot be hold responsible for. Indeed, tests worked fine here. However, nothing is impossible.
Info: When error occurs, the patcher can change the TCPIP.SYS back to the original!

Instruction:
Just download the patcher and execute it. It will automatically find the windows directory and ask, if it should increase/decrease. For higher values, please check the help with parameter /?.
After a successful patch, the new TCPIP.SYS will be automatically installed. After that, the computer should be restartet.

If you look at the front page of that site, here, you'll see that he's had a server crash, but that you can get the fix from here instead...
