Re: Internet Connection Lost After Installation of Windows XP Service Pack 2 (WinXP SP2)

Here's some more info regarding my setup and symptoms/causes.

First, all of my computers and the router are in the same subnet (given
their IP address), so I don't think there is a problem here. Plus,
this part of the setup has not changes from before SP2 installation.

Second, MTU shouldn't be an issue here. Again, this setting hasn't
changes since before SP2. Also, I can't access any websites
whatsoever. In fact, I can't even view the web interface of my own
router. Notice (see the original post) that the latter seem to
disappear "gradually". It was accessible and fine from my laptop, then
I could access it from my desktop, albeit very sluggishly, and finally
it disappeared altogether (from both laptop and desktop). This gradual
aspect has me quite confounded. Is it possible that my router gets
flooded with packets from my desktop? Something to the effect of
denial of service attack issued from my own box?

Third, I need to point out that I had, in fact, run LPS-Fix prior to
installing SP2. It found some stuff and removed it. Also, after
installation of SP2 its built in malware-removal tool seems to find
something and remove it. I can't remember off the top of my head what
exactly that is - some dll.

And finally, I have port forwarding set up in my router for HTTP (port
80) to my destkop. I run a web server on my desktop and I need it
visible from the outside world.

I'll post more info: HijackThis log and outcome of WinSockXpFix later
today.

Thanks for your help,

Andrew
