Your edits confused the issue a bit. MQSeries has the same problems as IIS, since the port appears in-use all the time (and cannot be used by either IIS or MQ). I'll edit to make this clearer.

Thanks! At least I now know that I haven't gone completely insane. For a while it seemed like I was the only person on earth who did not think that the question was completely off topic.

Yes, I realise that and I agree. I was just thinking about the typical problems I myself run into (I am a 70% system engineer/30% developer according to my job description) tend to be can-work-on-it-for-a-day programming problems and must-be-fixed-immediately system configuration problems. That said the only (real) question I posted here so far is a can-work-on-it-for-a-days system configuration problem.
