Hi Ted,
I am in your first category. I have a small 802.11b home
network (2 PCs), running eTrust Firewall, eTrust AV,
Spybot, AdAwareSE, Spywareblaster, and SpySweeper. I
have a D-Link router, a D-Link USB adapter on the
desktop, and built-in WLAN on the laptop. Been running
smoothly this way for over a year. But, like you
describe, I thought it was time to install SP2 and wasn't
too worried. I installed all my PC and software makers'
patches for pre-SP2, then performed the update.
As soon as the install was over, I'd lost all my network
and Internet connection. After literally hours
repeatedly configging (and resetting, and reconfigging)
my router, removing & reinstalling Windows network
connections, and talking with D-Link support, the tech
finally got a 'supervisor' who told me that it's an SP2
issue, and my equipment won't work with SP2 installed
until Microsoft puts out a fix.
Left with no choice, I rolled back to pre-SP2. But my
connection to network/Internet was still gone. Took
another couple hours with tech support to get everything
back up and running.
But now, as I've described in another post, the operation
and performance of both PCs are seriously degraded. It
is a marked difference from before, and I'm completely at
a loss to understand it.
My point is, I felt about as safe as I could, and
something still went terribly wrong with SP2. And now,
of course, all the tech-support departments blame each
others' products, and I'm left with two crippled PCs and
no support whatsoever.
I'm sure others are able to install without difficulty,
but clearly many people are having huge problems. Just
wanted to add my $0.02 to the mix.
Now, back to my troubleshooting......
