This is not an answer to the letter of your
question. I sympathize with you. I rarely
need to know things about Microsoft OSes and when I do have no
clue where to go for help. In the future I will probably, if the
nature of the problem seems to suit, try
the Chatterbox here.
The Debian mailing lists are useful if your
linux is Debian.
There is a knowedgable old guard still following
some of the comp.* groups. If you can learn programs
like trn or tin newsgroups aren't bad, I haven't found
a GUI newsreader that lets me go through a voluminous
group as easily as trn.
