How do I use "Why Can't I Connect?"
Search the computer for ports in use / connected ports, listening ports, reserved ports, and all ports that can not bind.
Enter the starting number of the range of ports to be tested.
Enter the total ports to test. Enter 0 to test all remaining ports.
Select the type of test to run on the ports.
Test for ports in use / connected ports.
Test for listening ports.
Test for reserved ports (ports reserved by the operating system).
Test for all ports that return an error while binding.
The 'Show Trace Message Boxes' check box is a convenience for turning off trace message boxes during ports in use testing (there may be many errors.)
Release 1.9.1
Release 1.9.1 is now available.
In this release:
1. Changed the url of the Knowledge Base to match the website redesign.
2. A minor cosmetic change.
3. A minor bug fix.
The new website design is friendlier but required a remapping of the pages.
I removed the border around the visible trace list.
If loading the dll for ICMP fails, I disabled the neighbors tool. I now only disable the use of ICMP echo requests. ICMP is only available in Windows installs.
