Or open a command-line console and run the command "ipconfig /all".  It
will tell you everything you never wanted to know about your current
network connections. :-)

Sometimes just running the commands

C:>ipconfig /release
C:>ipconfig /renew

will take care of it.

Firewall is new with SP2.  When you install SP2, it defaults to
enabling the firewall, unless it detects that you already have another
firewall product installed.  I know it detects ZoneAlarm, because it
detected mine and defaulted the Windows Firewall to off.  Since it
detects that one, I'd guess it also detects the major players in the
Windows firewall market.  If the problem started soon after an SP2
upgrade, the firewall is low-hanging fruit for being the problem.

I totally agree.  At Wal-Mart, Target, etc., you can get a small device
that's usually called something like a "Cable Modem / DSL Router" that
has not only the network router but also a firewall, and a four-port
Ethernet (10/100BaseT) switch or hub for about US$40.  Some of them
even have a built-in Wireless Access Point.

Personally, I splurge another US$40 or so and get a dedicated 10/100
switch and connect the router to the uplink port on the switch and
connect the computers to the regular ports.  Some of the "Cable Modem /
DSL" routers put their ports into the DMZ or directly onto the
internet, rather than having them behind the built-in firewall.  With a
switch between the computers and the router, they're all behind the
firewall, they're all NAT'ed, and they get their IP addresses from the
router automagically.
