I think this is great, and I agree it may be the time to talk about windows 2003 and SQL server 2005.

It is quite difficult to find the documents about maintenance each node or trouble shooting.

If you can provide that topic (let's say possible problem and answers etc), I will be really appreciate.

I saw just only one webcast from Microsoft about trouble shooting but it does not provide much in detail.

I am working in the corp that does not have clustering, so trouble shooting should help me gain the confidence.

If you can provide some resources or link, that will be great.
