Please help: Suddenly can't access Internet (SP2)

Hello everyone,

This will be long so you know what I've covered. Id be VERY grateful if
someone could take the hassle and assist please. I'll try to make it strictly
to the points needed. I've tried everything most people know and I've failed.
The only step left is a repair install or a complete install now that I can
think of.

I have Windows XP Professional with SP2 and all the latest updates. Till
this week I've had no problems with it. My hardware is fairly new, absolutely
nothing, not even a single cable is faulty (all cross checked), nor my hard
disk nor the OS in general, nor are my internet connection, router, or
settings bad in any way. They are how it used to be when it all worked,
without any change. I used to be an electrical engineer from '82-'84 so I
know most hardware basics. I was also a programmer from '83-'86, so I do
recall minimum essentials.

--------------

I have 2 systems here, one was fully working and one was always giving an
error.

The MAIN one is a new system that was fully working. Everything was as
expected and the HDD's are good and new. It's my work system given at home
and it has over 1TB on 3 partitions of a single HDD with the OS, and a
perfect 50MB network connection usually. Software installed, work, personal
hacks, additions, customization is so much that it is a matter of 6 months
work just to be able to copy it over to a replica state I need for work.
Frankly, I don't have the time at all and this happened at the worst time!

I was troubleshooting a system that was giving me a 0x07b BSOD at bootup. It
had it's own HDD and OS (XP Pro SP2 64-bit). After a few weeks I took a risk
and swapped my HDD from the MAIN system above (after clearing drivers) into
that to see if that would bootup or if it was an OS error. It didn't, same
error received after POST.

--

So I swapped it back in to my MAIN system to continue work as usual. My work
is heavily net dependent. On bootup, all is fine, all the peripheral
components are detected and their drivers installed, the same versions as
before from a USB. I reboot again to my desktop. First failure came up: "AV
could not connect to the Internet, so update failed!" I use a 4 port router
with built in modem and broadband over PPPoE. Onboard Ethernet.

Well I tried to check in Control Panel>Network Connections and it showed me
"connected", which means everything from behind is OK until the OS:

However, as you can see, NO data packets, incoming or outgoing. I tried to
view properties, and it was all blank! I checked the TCP/IP properties and
all was the same as before. So next I tried opening my browser and I get
this: http://i131.photobucket.com/albums/p286/Kab_Moz/Fx.jpg

Funnily, absolutely nothing has changed in terms of components, hardware but
I don't have an internet connection anymore!

So I go back to Network Connections and I try a "Repair". This is what I
get: http://i131.photobucket.com/albums/p286/Kab_Moz/Connectionfailed.jpg

TCP/IP error.

Hmm.. so next I reboot into Safe Mode. Same problem. In Safe Mode I
UNinstalled all my safety components, security related such as AV, firewall
etc., reboot and I get the same problem with absolutely nothing but basics
running.

-Next I try Last Known Good Config. No difference,.
-Next I try a System Restore, I keep the best ones saved all the time- I
KNOW it was on before I swapped HDD, enough space too, but now there is
nothing saved there anymore - no restores available though System Restore is
running. :(

So I tried to PING and check IPCONFIG. This is what I get:

-------------

D:\Documents and Settings\Home>ping 127.0.0.1

Pinging 127.0.0.1 with 32 bytes of data:

Hmm.. something seems to be blocking the connection.
I had made an OLD backup of this same OS on a HDD that was in the US, while
I have flown to EU for business now. I had it sent over to crosscheck. It was
the a copy of the SAME OS but missing 190GB of differences. Hooked it up and
the Internet worked perfectly!
I had a spare unused Vista Ultimate from work, installed it on a 40GB HDD,
on the same system, it worked!
I had a HDD with 5 Linux distro's multi-booted setup anyway. Tried that and
everything worked! Even the internet, yes.

Back onto the MAIN HDD that I need to work:

-I checked all my services and everything was the same as before and
running/disabled as needed.
-I ran sfc /scannow and it did it's work.
-I cross-check my old backup OS, winsock, router, BHO settings and there was
NO difference.
-I did malware, virus, trojan scans, all was fine.
-I then proceeded to deleting, reinstalling drivers.
-I tried removing most programs even remotely connected to Firewall/AV/AS
completely at the risk of malware infestation.
-I tried checking the Router Settings through browser (doesn't connect).
-I checked the firewall logs.
-I removed the HOSTS file.
-I checked Event Viewer logs. Nothing extra mentioned BUT no TCP/IP Ethernet
adapter detected as normally done like this:
http://i131.photobucket.com/albums/p286/Kab_Moz/TCP-IP.jpg
-I reset/repaired the TCP/IP stack. I even ripped it again so it would
uninstall and reinstall.
-I reset the Winsock, through command line and manually by deleting the two
reg entries.
-I reset my router.

Absolutely the SAME problem exists and I've redone this all rebooting after
each command at least 30 times now. I'm now fed up that there's been bug of
some kind that's messed my OS up or something I can;t explain. I am having to
reboot into the OS time and time again for access to information and it's
costing me badly. I was at the Indonesian earthquake doing my duty when this
happened. You don't want to know how distressed I was.

Can anyone please help? I would be grateful and would do my best to try
anything. I can only see a repair install coming now and it will make me lose
so much customization and hacks that I'm in scared to go there.

A full install, again this year is just NOT an option. That would just be
ridiculous.

Thanks.

Hello,

Try these ways
1) UNINSTALL your network adaptor from device manager and reinstall it back
2) Try the solution posted here
http://msmvps.com/blogs/bgb/archive/2005/06/09/51432.aspx
3) Try replacing tcpip.sys in safe mode from another PC
4) And finally this - http://kentwell.net/glenn/14 (disable and enable
TCP/IP on network properties)

Hello SingaporeWebDesign,

You are phenomenal! Thank you very much. It is working now, fully. :-D

I tried 1) that you noted, even though I had done it previously 40 odd
times. The only difference in my procedure being this time to not reboot and
then install the Ethernet adapter, but install straight it after
uninstalling.
One other difference being that it seems I have 2 Ethernet adapter listings,
one labeled "Ethernet Adapter" and the other being "Ethernet Adapter
mini-port". The latter is what was needed and worked.

Internet is now running as normal as possible.

I feel pretty bad that I can't offer you something in return. :-(

Let me know if ever there is anything, for sure!

One again much appreciated.
