I have a rather curly Tech querie ...
I have recently encountered a similar problem on both a computer running WinME and also one running Win98SE, where both of these machines had lost ability to connect onto the internet and or LAN. Tried reloading the relative Windows on both, completely killing all networking setup and reinstalling, up-dating the DUN, stripping modem & LAN card drivers, [also tried replacing the winsock files,] and scouring the registry for incorrect / odd entry of TCP/IP ,dialup, & network etc. links ... [as well as updating Internet Explorer]
I could eventually get the dialler to work and logon manually - but not one app. or browser could see the internet connection - some stating there was a DNS error. ...
The only way to restore networking and dialup linking on the Win98 machine was to format and reload the OS ... which is too severe a solution for general use (but, unfortunately, often too necessary).
So what I am wondering is if anyone may have encountered a similar problem and had a quick fix other than the complete re-install of operating system ...?

I have run into the exact same problem twice. On both occasions it was a crappy NIC card. Another thing to look at is protocols and make sure they are correct. Ive seen a few W2K boxes that woulod never see the same tree as the others in a Netware volume and it was found to have different default protocols added.
I'd check the cards first, try swapping with a working card from another box.

The trouble with one machine is its a notebook - so swapping network cards is impossible - I did disable it and stripped all drivers and anything else related from the registry, I even totally eliminated MSIE using IE-killer which 100% removes MSIE and all related files and dll's. The first time I saw the same problem was running win95 a couple of years back and it did not have a network card or MSIE installed - But the problem appeared only after MSIE was installed and was browsing the net - next startup the internet disappeared - possibly picked up a malicious Java script or something ...

I rarely have a choice to reinstall the operating system, plus it takes too long.

I have seen this issue many times. And it's been a corrupt winsock.

Some of the obvious, empty temp internet files, cookies and downloaded programs folders. Change to the defaults in IE. Get the latest updates, blah, blah, blah.

To rebuild the winsock.

As you did delete all networking components. Uninstall DUN from the windows setup in add remove programs.

Then in the registry delete the listed keys from the following

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\

Winsock
Winsock2

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VXD\

AFVXD
DHCP
MSTCP
Winsock
Winsock2

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RemoteAccess\Authentication\

SMM

There's some files that need to be extracted from the setup disk. I extract the files first and put them in a folder then I write a batch file to automate the process in DOS.

cd\windows\system
ren filename.xxx filename.old
cd\folder (where files were extracted too)
copy filename.xxx c:\windows\system
The following files are the ones that need replacing.

vip.386
vtcp.386
vtdi.386
vudp.386
vdhcp.386
vnbt.386

This is probably pretty close to what you may have tried but perhaps it may help.

Thanks - didn't help completely ...
Now machine boots direct to windows ... So I edited registry at this key -
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Network\Real Mode Net - AutoLogon 00 <==== changed to 10
Restart now gives NT Domain Logon box ... Enter anything in domain window - hit OK in next box ... Now open properties for Netwok - and get properties for " Client for MS Networking" - uncheck [] Logon to windows NT domain ... Restart Now gives Normal LAN Logon box ... haven't tried this on any other machine yet ... of course may not work for anyone else ...
[p.s. Try XtreeGold to shift the files - from windows or pure DOS - no need for messy batch files ]
