When I use the Scanner tool in NetInfo on Windows XP Service Pack 2, I get an event log message with ID 4226. What do I do?
By design Windows XP Service Pack 2 limits the number of simultaneous incomplete outbound TCP connection attempts to 10. After the rate is reached, subsequent connection attempts are placed in a queue eventually to be resolved at a fixed rate. This slows down programs that open multiple TCP connections at once. The Scanner tool is a good example of this.
