Lost all broadband and dial-up Internet connections

I don't know what happened, only about late afternoon
12/20/03. I had uninstalled the video driver (had been
installed twice), then MS auto-update informed that I
needed to download/install critical updates (my other
computers did not get this update message...??). I allowed
update to proceed (did not pay attention what it was for).
I then re-installed my video driver. Not long afterward
was when I discovered I could not access the internet on
broadband, and not even on dial-up to AOL.

Is there any setting in Win2000 or the registry that
forbids TCP/IP access that could have somehow been set
that way? I can see how one or the other connection device
might get messed up, but not both at the same time....????
 
I hope you did not install the video drivers until you rebooted the machine after
installing the critical updates or problems can occur. You could try going to control
panel/add and remove programs to remove the critical updates to see if it helps. It
may also be worth a try to boot into safe mode with networking to see if you can
access the internet which if successful would indicate problems with drivers or a
startup program.

Basic network troubleshooting would involve using ipconfig /all to examine ip
configuration, running ntediag looking for failed tests, and using utilities such as
ping, tracert, and nslookup. I would first try to "ping local host" , and if that is
successful ping the default gateway [as shown in ipconfig /all] to see if you have
basic network connectivity. Then use nslookup at the command prompt to see if your
dns server is found. Assuming it is, enter Microsoft.com at the nslookup interactive
prompt to see if it can resolve internet names and if not you may have incorrect dns
configuration. You should also check Internet Explorer tools/internet
options/tools/connections/lan settings to make sure that a proxy server is not
enable - no check boxes or auto would be fine. --- Steve

Thanks for your suggestions... I checked the proxy setting
in IE and it's OK, I booted in safe mode with networking
enabled - did not help. I did try pinging the router
gateway IP (192.168.0.1) but it failed, and I also cannot
see any other computer in the workgroup (PTP network). I
tried some of the command-line commands, but they
failed... I really don't know much about networking, so
the tech stuff you mentioned is perhaps beyond me.

Can I re-install W2K, or would it just make a mess of
things? I am updated through SP4, but my CD is SP2...

Thanks

I would first try to reinstall tcp/ip as described in Knowledgebase article in
link below. If that does not help, you could try an upgrade installation that
would leave you data intact but require you to go to Windows Update and download
critical updates. If that does not work you would probably need to do a complete
reinstall by booting from the install cdrom and installing into your existing
\winnt folder that install would detect without formatting which would leave
your data intact [unless it is EFS encrypted] but again require you to install
critical updates and reinstall all applications on top of themselves. It would
also create a new user profile for you, but your old one would still be
available under documents and settings where you could copy your user
ta. --- Steve
