EventID 4226 TCP/IP - Connection Limit Fix
 

This is a new "feature" of Service Pack 2:

Information: The idea of MS is not bad to reduce the spreading of worms and other harmful programs. But 10 half-open connections is a little bit too less. With a higher (e.G. 25-100) number of waiting for connection connections the benefit would be almost the same, but less normal users would feel disturbed by this. The download and the instructions provided here are only for education purposes, how to set a higher limit. After the successful implementation, the user commits oneself to change it back to the original state!
