How to check half open limit in Windows [Video]

After Windows XP SP2, TCP half-open connections limit exists in Windows Workstation Edition.
You can use TCP-Z to modify this limit value in runtime, TCP half-open connections number will follow it to change.

This is a demo video, using a port scanning tool to initiate a large number of TCP connections, so you can easily check the limit.

Windows Server and Workstation based on the same framework, so the limit values also exist in the tcpip.sys of Server.
But Windows will never compare this value. There is no limit in the Windows Server Edition.
