Since yours is one of what appear to be scores, or even hundreds, of posts
along this same subject line I have to know the answer to a question that
has been nagging me for a couple of weeks. Why would you download and
install SP2 when there has been so much news about the problems it can, and
obviously, does cause? The newsgroups are now flooded with posts from
frantic users, just like yourself, who are shocked at the resulting chaos
SP2 seems to wreak on multitudes of systems.
The Microsoft Windows Update website has pages of information about what to
do to prepare your system for SP2. It even addresses the question of the
relevance of SP2 to the individual user.
I have seen SP2 installations go so smoothly you don't even know it has been
done. Then I have also seen, and been present during, the total trashing of
a perfectly good machine. There seems to be no rhyme or reason. I have
never been offered SP2 by Windows Update, which is on automatic to notify me
of updates available. It is configured to ask for permission to download
and install the updates as they become available.
I don't have your answer except to check this and the updates newsgroup for
help. These newsgroups are going to be your best bet to getting your system
back up and healthy again. This should serve as a critical lesson to you.
A lesson hard learned but one which will further your knowledge and
understanding of software, systems, and the people who make and own them.
Good luck!
