Great idea that quickly comes to naught, unless you know where the good information is housed.
At Error-Library.com you will find an extensive library listing of all types of errors, Windows Errors that is, although I am sure most errors are cross OS in nature. For example, you have just gotten the error I mentioned above, for example concerning port 6550 you can just go and seek out the information. Basically, from what I learned, a port is an application or process for communications 'end-point' for Internet use. Without having read at the website, I would not have known that.
If you have issues with port errors or other errors, go over to Error-Library.com and see if they can give you a helping hand.
