Windows 7: The DNS server isnít responding

After reading all the useful answers from knowledgeable people (thank you very much) I came to the conclusion that this issue is quite hard to point. I could try all the advices and don’t solve it, wasting your time because I sure would have to come back with the responses and get further advice. So I decided to restore the image I mentioned on my first post and go back to after uninstalling Comodo firewall with Revo and deleted a few more identified files by hand. Probably, others that I don’t know might have remained, and may cause some problem. At this point the browser goes to Comodo’s site when a site is not found, does not exist or because of a typing error.

No more the issue I described at the beginning of my first post, so I believe it will be much simpler to help me only to reset these settings instead of solving a complicated issue.

These are the images from the TCP/IPv4 settings and its 3 advanced tabs. The first IP address is Comodo’s, but the alternate doesn’t load.

-tcp-ip4_1.jpg -tcp-ip4_2.jpg

-tcp-ip4_3.jpg -tcp-ip4_4.jpg

However, the problem with the SFC remains, I don’t know how.It is prior to taking the image, but it is new. Maybe it has the same origin from uninstalling Comodo, but I don’t know. The scannow result is the same:
Windows Resource Protection found corrupt files but was unable to fix some of them.
I scanned three times with the same result at the end. I am attaching the log file because the command to get the sfcdetails.txt on the desktop as in the tutorial doesn't work for me. What files do I have to replace?

Shouldn't we be trying to remove all traces of Comodo? Read carefully and use CCleaner to remove the registry entries.

I followed the instruction, but finished with Little Registry Cleaner from SourceForge. However, the browser keeps jumping to Comodo's site (example), replacing the sites or browsers error pages with their ad index and useless information.

It did not change anything with TCP/IPv4 settings, which are still the same as on the images on my last post. After reimaging I am at the point when I uninstalled Comodo with Revo. Later, when I found that thing about the browser, I tried to clean the registry with LRC with no effect just as now. I need to reset the TCP/IPv4 settings. I Thanks for trying.

Let's see if this batch file works ... I think Comodo (don't know for sure) may still be hooked to the Layered Service Provider (LSP)

Copy and paste these lines in Note pad.

@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0


Save as flush.bat to your desktop.
Double click on the flush.bat file to run it.Vista and Windows 7... right click the .bat file and choose to run as Administrator. Your computer will reboot itself.

Let us know if that worked or not.

Pity, Jacee, nothing changed, all settings are still as the snapshots on my post, and the browser too.

While the batch file was working there was a short pause where I could glance that some command could not because because something that was active. I didn't have the time to read it.

Download DDS from one of these links:
DDS.com
DDS.pif
  • Disable any script blocking protection
  • Double click the dds icon to run the tool.
  • When done, DDS will open two (2) logs:
    1. DDS.txt
    2. Attach.txt <--- will be minimized in the task tray
  • Save both reports to your desktop.
Include the contents of both logs in your next post.
The scan will instruct you to post Attach.txt as an attachment.

Hello Jacee, thank you for trying. I hope this will allow you to help.

Here are the resulting files. I thought file dds.txt, with some uncompressed 27KB, bigger then attach.txt (16KB), was a bit too long to post it in the post body, so I attached it too. If you want any change, please say so.

I read some references to Comodo close to the beginning of attach.txt, under "Disabled Device Manager Items", but cannot find it in the computer. Also, their IP numbers, as they appear on the TCP/IP images of my post, are there. AMD Fuel is mentioned as a started service, but I have not that; it does appear on Task Maneger as stopped, and if clicked to start it says it can't find the file. I didn't read anything else. Please, remember that I installed a saved image less than two days ago, as mentioned on my post with the TCP/IP images.

Thanks again.

Why not start by removing Avast completely from your system?

avast! Uninstall Utility | Download aswClear for avast! Removal

There are also components of Comodo that need to be removed.
