Non-Midrange resources kind of like Midrange dot Com

I know this isn't a PC Tech issue, but I recently inherited management of
130 windows servers and various network appliances. I also know that there
are a lot of resources on the internet that provide a "Midrange-like"
technical community.

So in trying to narrow it down, I'm hoping some of you who also manage a
windows server farm and network appliances, can point me to a few of your
favorite/useful websites where I can solicit information about tools used
to manage windows servers, and network appliances the likes of those
offered by Barracuda for internet content filtering, email spam filtering,
email archiving, intrusion detection, firewalls and so forth.

We have VMWare and use a lot of Cisco products, and Barracuda appliances.
And today the Barracuda web content filter started acting flaky and their
support recommended a 'rebuild' of the device (which is similar to a
format/reinstall of windows) and my network engineer did that last year,
and they are asking him to do it again. So I'm thinking it's time to start
shopping, but I don't have any good internet resources other than google to
start with - and trying to narrow where the smart people go to get reliable
answers.

And as a side note - just today we had an SQL server slow to a crawl, and
the application vendor's solution was to defrag. I had to point out to my
server admins (and my boss) that defrag was something we in the midrange
world stopped doing when we left the S/36 for the AS/400 almost 25 years
ago (ZING!).
