Access to LAN, No access to Internet

I have a wired home network and DSL. DSL modem, D-Link router/hub, 4 desktop
computers (2 with XP SP2 and 2 with XP SP3). Everything worked fine last
night. This morning, all the computers except one work fine. The
dysfunctional computer (Dell 1100 with SP3) cannot connect to the internet
now, though it can still connect with the other computers on the LAN and the
other computers can connect to it. This is just the opposite of any network
problems I have ever experienced, since it is usually trying to connect to
other computers that is problematic, not to the internet.

I have checked all the connections, restarted the computer, uninstalled and
reinstalled the network card driver, ran the network connection wizard again,
ran LSPfix (no problems found), totally turned off all of Norton 360's
firewall, autoprotect etc., and have now hooked up my laptop to the LAN cable
that was running to the problem PC, and can connect to the internet just fine
on it (I am on the laptop writing this now).

A couple of other oddities that someone may be able to connect all the dots
together and know what the problem is. I cannot access the router via
Internet Explorer nor ping it from a command window from the problem PC, and
even though I can access all the other PC's via Windows Explorer (I even
copied files between them to make sure), I cannot ping any of them either.

I tried doing a system restore to yesterday, even though I have made no
changes to the system in a while now, and it failed. I believe this is due to
having the Truecrypt encryption program on 2 of the 3 partitions of the hard
drive, though not on C:\ where the operating system is. I think I found out a
long while ago that system restores always failed when Truecrypt was
encrypting any partitions on a drive at startup, even if the one the
operating system was on was not.

I am not an expert, but not a novice either, and this is way to confusing
for me.

Any thoughts would be appreciated.

Have you restarted the router during all this diagnostics?

My routers sometimes fail to let one PC thru to the Internet and
several other times I could not access the router(s)' web
configuration pages. A restart of the router usually fixes this.

If I were any more embarrassed, I don't know what I'd do. I am writing this
on the now-not-dysfunctional desktop computer, many thanks to you. I have had
routers do some strange things over the years, but this is an entirely new
one for me.

I actually thought about restarting it a couple of different times through
this mess, but then thought "Naw, not just the one computer. Restarting that
computer would have fixed that." Add a little laziness on my part, not
wanting to kick 3 other people off while it shut down and restarted, and here
I sat with my laptop in front of my desktop's screen. I even dug out a LAN
switch/hub I had gathering dust in the closet and put it on the end of the
LAN cable running to the desktop computer, hooking both the desktop and the
laptop up on it. The desktop still acted the same.

So simple a thing to do, so irritated I did not do it to begin with!

Again, thank you very much:)

Yeah I know! I have several clients with over 64 users all connecting
to the Interent over a router. It is a "PITA" problem to restart the
router but like all f@#@ ridicluous electron device (FRED) the power
and environment can affect the unit.
