2) Please include as much information as possible, which means "IT'S NOT WORKING HELP" won't do, nor will "it crashes".
Since it might be hard to figure out which piece of information might be required when you're dealing with an issue, here's a list of common ones:
a) Where are you, as in, at which screen, in which program, etc.
b) What was your last action before the issue happened.
c) Which version of Windows are you running? ME? 2000? XP? XP SP2?
d) What is the exact(!) error message?
e) Is it a consistent bug, are you able to get around it, and are you able to reproduce it at will?
f) Which steps have you already taken to try and fix it? This step is in fact very important. If you do not include this, do not expect to receive help
g) Which router/firewall are you using, and have done anything to set it up for SoD?
