Prevoius Hosts File Lingering and Causing Internet Disconnection. Please Help!!!

[No Way]

I used to use this HOSTS file which was about 500KB big and it mostly
consisted of all these spam links that'd be looped back to localhost.

But soon after I started using it, I noticed that I'd have these
intermittent internet disconnections, so, I removed the said file, but
for some reason, even after reboots AND now, even after having reset
my Winsock2 and TCPIP by following the instructions listed at this
link,
http://nitecruzr.blogspot.com/2005/05/problems-with-lsp-winsock-layer-in.html
, and even following the instructions provided in the links on that
page, I'm still experiencing problems.

What would happen is, I'd be using the internet just fine and when I'd
click on something that I believe was blocked in the previous HOSTS
file. So, both the IE ane the Firefox would display that the site is
not reachable or the server is not responding.

But when I try to access other sites which were not in the previous
HOSTS file, I'd lose connection with the same message. So, I'm left
to reboot to regain my internet connectivity.

I have even powercycled my modem and my router, reinstalled my onboard
ethernet device, reset and reinstalled my router and still
experiencing the same problem. When my internet connection goes, I
can't even access the admin page of my router which I get when I type
in 192.168.1.1 in the browser.

Oh, when I do experience an internet disconnect though, the 2 other
computers connected to the router and the xbox and the xbox360
connected to it can access the internet just fine.

Does anyone have any suggestions as to what I should check to see
that's causing this? I'm willing to try anything at this point, short
of doing a clean reinstall of my Windows XP Pro SP2. TIA! Please
Help!!

Oh, and yes, I have checked for viruses, spyware and adware and found
none.

Sorry, one more thing, this is the .BAT file that I used to install
the previous HOSTS file. I did run the contents of the dir this .BAT,
the HOSTS file and a couple of readme files extracted to from a RAR
file through a virus scanner and it was just fine. Please have a look
to see what might possibly be causing this problem. Thanks again!
