inzider
What is inzider?
This is a very useful tool that lists processes in your Windows system and the ports each one listen on. At the moment I haven't seen any other program that does what inzider does. Unfortunately there are some stability problems due to the somewhat "strange" techniques inzider uses. I guess there is still much left to wish for, but over all I think inzider is a success, and it's quite popular despite the problems. On Windows NT, inzider is still unable to check processes started as services. Yet, it's very useful - for example, check out this page about inzider vs. bo2k (Back Orifice 2000). Keep your eyes open in the future, there will most likely come new improved versions.
Where can I get the source?
Nowhere. I don't give out the source. Please respect this and don't ask for it, I make no exceptions. Or, well, if you can get me the complete Windows 2000 source in exchange I'll consider it... ;)
How do I use this tool?
Download the install program file and run it. The install program is created with the freeware (for non commercial use) GkSetup written by Gero Kühn. After installation, run inzider from the Start menu. It will take some seconds and then you will see a list of processes and which ports they listen on. Sometimes all processes aren't listed on the first try. If this happens, close the program and restart it. Repeat this until all processes are shown (which usually takes at most 2-3 tries). To minimize the risks of experiencing problems, please save all unsaved work before running inzider. Also close any valuable documents and similar that you have open. After you finish using inzider, reboot the system to guarantee it's stability.
Which OS's are supported?
Windows 95/98, Windows NT 4.0 and Windows 2000.
