Event ID 4226 Patcher (4226 fix)

What's this all about?
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
- a small amount of time
What's been done:
To say it easy: the before 10 half-open connections are beeing increased to 50 (can be changed during runtime and with the parameter /L) and the CRC is been corrected. And that's it!
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! 
 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 restarted.
