Windows Forum / Windows Me / Internet / December 2005Internet connection - can't find DNS any more
I'm cleaning up a friend's Toshiba laptop which had been infested by spyware, adware, keyloggers and trojans. After it was cleaned, I created a Dial Up connection with the 56K internal modem, and connected to my ISP OK, with full Internet and POP e-mail access. The machine seemed clean and useable with correct acces to the Inernet. However the machine has not been kept up to date with Windows updates, and the 56K modem would never have been a viable option to process all outstanding Windows updates. I installed a USB Wifi connection so I could connect the laptop to my broadband connection through my network router, and downloaded and installed about 60 MB of Windows updates. When I then tried connecting the machine through the Dial Up internal 56K modem (to be sure all was still working OK) it connects to the ISP but it can no longer find any sites. I have not made any changes to the DUN or TCP settings - so I can't see why it won't find any site names - it was working OK before the update. The ISP provides a valid IP address - Winipcfg looks normal, and the DNS names displayed are as expected. Unfortunately, the machine is installed with the Swedish language (which I can barely understand), and I am concerned I may have done something stupid during the update, because of the language difficulty. I think TCP is OK as it connects to my network using the USB Wifi. However, I can't ping my ISP's DNS server. Does anyone have any idea what may be the problem and what I need to do to fix it? thanks GB Run the LSPFix from here http://www.cexx.org/lspfix.htm  SignatureNoel Paton (MS-MVP 2002-2006, Windows) Nil Carborundum Illegitemi http://www.crashfixpc.com/millsrpch.htm http://tinyurl.com/6oztj Please read http://dts-l.org/goodpost.htm on how to post messages to NG's > I'm cleaning up a friend's Toshiba laptop which had been infested by > spyware, [quoted text clipped - 39 lines] > thanks > GB Noel, thanks for the link. I tried that last night, plusa similar one from Adware. No joy with either. Problem remains. I tried reconnecting through the Wifi and that still works. I presume the DNS is being picked up through the router and its DNS linkage, but the recognition of DNS through the standard Dial Up modem still doesn't work. I can ping localhost and 127.0.0.1 OK. I tried pinging one of the redirected sites located in the HOSTS files, and that returned 127.0.0.1 OK. So, it seems that TCP/IP is OK? I'd hate to have to reinstall TCP (because of the Swedish language problem - I can't see what I am doing!). There is a Winsock.dll, dated about 2001. I'm completely stumped - desperate for suggestions.

There probably is a proxy server set, as I usually use the ISP's proxy. I can't see, though, if that is the problem, why it worked before I installed the Windows updates and then failed to work afterwards.

Deleted and reinstalled TCP - no joy. I can still access the Internet via the USB Wifi, but not via the 56K modem. Looks like a re-install :-(( sigh! Thanks guys for the help, though.

The Modem dials up the ISP and connects OK. But I can't ping any external address, nor get any DNS resolution for the Internet. I have tried connecting with a different laptop and modem, noted the ipconfig results, and then compared it with the problem machine ipconfig. Results are identical. I can connect the problem machine via a USB Wifi adapter through my router - all that works fine. I 'll try looking for a modem driver update, maybe that's the problem. Alternatively, I can try to undo the Windows updates, or else try a System restore to the point prior to it all going pear-shaped. sigh!

You do have the browser set to connect through the modem, don't you? - not through the LAN???

I stopped effing around and ran a system restore from a week ago, before I installed the USB Wifi and ran the Windows updates. 10 minutes and all was restored to full working order! I don't say it often but let's hear it for Windows Restore, folks! Still don't know what the problem was - perhaps some screw-up with the USB Wifi, or possibly the Windows Update. However, the machine is back to operational status, and I can make some progress with it now. Thanks for the help and support - it kept me sane when all else was falling apart :-)) cheers GB > Check your firewall isn't blocking? > You do have the browser set to connect through the modem, don't you? - not [quoted text clipped - 200 lines] > >> >> >>> >> >> > names - > >> >> >>> >> >> > it Great news.
