[FONT=Times New Roman]Hello all,[/FONT]

[FONT=Times New Roman]I have an annoying problem that prevents me from using my laptop properly.[/FONT]
[FONT=Times New Roman]First of all, I get this error for every page I try to open in Google Chrome:[/FONT]
[FONT=Times New Roman]"This webpage is not available[/FONT]
[FONT=Times New Roman]
The webpage at <any url here> might be temporarily down or it may have moved permanently to a new web address.[/FONT]
[FONT=Times New Roman] Error 137 (net::ERR_NAME_RESOLUTION_FAILED): Unknown error."[/FONT]

[FONT=Times New Roman]Secondly, no software can connect to the internet to update itself; for example, when I tried to update Malwarebytes, I got this error:[/FONT]

[FONT=Times New Roman]Finally, from time to time I get an error window from BackupManagerTray (I think this has something to do with Acer BackUp) which states: “The TCP/IP protocol is not installed properly”.[/FONT]

[FONT=Times New Roman]The first thing I did was to check if I actually have an internet connection - by using 'ping google.com' in Command Prompt, I discovered that I did. Afterwards, I tried to open Internet Explorer and surprisingly, browsing worked just fine - yey for me![/FONT]

[FONT=Times New Roman]As I had previous problems with malware and viruses, I tried to disinfect my laptop by using the following software: Bitdefender 2011, AVG 2013, Malwarebyes’s Antimalware, Kaspersky Virus Removal Tool (website version) and TDSSKiller. Some of them found several infections which were cleaned, but my problem persisted.[/FONT]

[FONT=Times New Roman]I figured there must be a problem with my IP/DNS configuration. In Command Prompt, I tried to reset them by using ‘netsh winsock reset’(and similar commands), but with no result. I have also tried ‘sfc /scannow’ but it didn’t find any problems with the system’s integrity.[/FONT]

[FONT=Times New Roman]I ran out of options and I really don’t know what to do anymore. [/FONT][FONT=Times New Roman]If anyone experienced this or has an idea about what my cause this problem, please help me![/FONT]
 
Ok, let's go thru the TCP settings.
get a command prompt and enter IPCONFIG /ALL >myTCP.txt
then open the myTCP.txt file and look/report these values:
  1. Node Type . . . . . . . . . . . . : Hybrid; if it is anything else, we need to fix it
  2. DHCP Enabled. . . . . . . . . . . : Yes
    Autoconfiguration Enabled . . . . : Yes
  3. Default Gateway . . . . . . . . . : 192.168.0.1
    DHCP Server . . . . . . . . . . . : 192.168.0.1
  4. DNS Servers . . . . . . . . . . . : 216.116.96.2
  5. NetBIOS over Tcpip. . . . . . . . : Enabled
the BOLD items are a must, the blue ones must exist but may be very different
 
Hello Jobeard,

Thank you for the reply. I have done as instructed and the report seems OK; the bold ones are as described and the blue ones are slightly different. Do you require the values?

Regards,

Mirela
 
Do you require the values?

NO.
get the cmd prompt again and run these tests
  1. ping 8.8.8.8
  2. nslookup 8.8.8.8
  3. ping google-public-dns-a.google.com
1) seeing time values and no timeouts says you have a valid connection to your ISP and you can send receive packets.
2) that address corresponds to the name in (3) and that's what should be see as the response. This means you can correctly use DNS to map an address to a name
3) should return the address seen in (2) and says your DNS can map a name into an address (which is needed in every request from every browser).
 
Just did it and it looks OK to me. I have copied the results just in case you need to check them:

PERFECT :)

Than implicates the browser(s) which are failing.

DISABLE all addons in every browser.
Empty the Cash of each.

oops - forgot to also say, under a command prompt
  • ipconfig /flushdns
  • net stop "dns client"
  • net start "dns client"
 
Ok, let's get specific
get the version of IE and a url that is responding

repeat that for each browser installed (cite name, version, and results)
 
Also pls report the anti-virus program and version installed and *IF* you have it active
 
[FONT=Calibri]Every website is loading perfectly on IE (v.9.0.8112.16421 64-bit Edition) - techspot.com for example; [/FONT]
[FONT=Calibri]On Google Chrome (Version 22.0.1229.94 m) I get the same error I mentioned in the first post on every URL:[/FONT]
[FONT=Calibri]"The webpage at <any url here> might be temporarily down or it may have moved permanently to a new web address.[/FONT]
[FONT=Calibri]Error 137 (net::ERR_NAME_RESOLUTION_FAILED): Unknown error."[/FONT]
[FONT=Calibri]On Opera (Version 11.61) I get the following error on all websites:[/FONT]
[FONT=Calibri]“Internal communication error[/FONT]
[FONT=Calibri]Check that the address is spelled correctly, or try searching for the site.”[/FONT]
 
I currently have AVG 2013 (2013.0.2740) on my system and it's enabled. However, I cannot update it just like I cannot update anything.

let's focus on this single URL.[/FONT]
[FONT=Calibri] [/FONT]
[FONT=Calibri]We have proven that your TCP connection to the ISP is just fine - - it's got to be elsewhere.[/FONT]
[FONT=Calibri]Which version of Windows are you running?[/FONT]
[FONT=Calibri]Are you running from an Admin login or a LUA/UAC limited account?[/FONT]
[FONT=Calibri] [/FONT]
[FONT=Calibri]If you use SERVICES.MSC you can enable Secondary Logon and get two users running at the same time: here's how[/FONT]
[FONT=Calibri]get a command prompt[/FONT]
  • runas /user:administrator cmd
  • <enter the password>
notice the window title will show something suggesting Admin (os version impacts the display),
but also the current directory will usually be \windows\system32

that window will have Admin privileges :)
enter services.msc

now STOP the AVG services (any/all)

From any LUA/UAC account access http://ww.techspot.com in each browser and report back

btw:

is this directly from Chrome or are you looking in the Event Viewer?

[FONT=Calibri] [/FONT]
 
[FONT=Calibri]I am running from an Admin login and I always open Command Prompt with admin privileges. [/FONT]
[FONT=Calibri]I opened the services window, tried to stop the AVG service (only one was running) and I couldn’t; the Stop button from the Actions panel was disabled. However, I changed its Start-up type to ‘Disabled’ and restarted the machine. The same errors popped when opening Chrome and Opera, while IE is working fine.[/FONT]
[FONT=Calibri]The error is directly copied from Chrome.[/FONT]

1) you should NEVER be browsing the Internet using an Admin ID - - use that only to install MS Updates and to install new programs. Using it day-to-day increases the chances of infections (but you've already paid that price).

2) AVG has a means to Temporarily disable AVG -- use it to disable ALL functions of AVG.

retry https://www.techspot.com from all browsers.
 
[FONT=Calibri]1) I never thought of it until now, but it makes perfect sense. Thank you for the advice, I’ll make sure to change my usual account after I solve this issue.[/FONT]
[FONT=Calibri]2) I have disabled AVG’s protection but I get the same errors when trying to access techspot.com[/FONT]
 
Can you use IE to download Avast! If so (do that first!!!), I would recommend
go offline (disconnect from your router)
  • uninstall AVG
  • Install AVAST!
  • reboot
  • reconnect to the router
retest all

correct.
The sequence is this:
  • create a new user-login, give it Admin rights
  • THEN change the rights of your current login to LIMITED.
You do not need to change the current login name,
especially if you are logging in under ADMINISTRATOR or OWNER.
 
[FONT=Times New Roman]Sorry for the late reply, my internet connection is far from best and it took a while to download the Avast! kit. I did as you told me, checked the browsers but with no result. [/FONT]
 
Let's pick on Opera;
  • get the tools->Prefs->General
  • ... set homepage to www.google.com
  • click Advanced->Content
  • click Blocked Sites; delete any/all
  • click History->Disk Cache -- Empty Now
  • Cookies->accept ONLY from sites I visit (all others unchecked)
  • Security->Security Protocols -> enable ALL
  • Network->Proxy Servers ->(*) Use manual but EMPTY all inputs
  • Toolsbars-> Toolbar setup -> select standard_toolbar
  • ....-> Menu Setup->Opera Standard
  • ....->{x} dbl-click text to display context menu
close the Opera browser and relaunch; does it access Google?
 
[FONT=Calibri]No luck unfortunately; it won’t work, I’m getting the same error. I’m starting to think it might be a general issue, not just related to browsers, since I cannot update any programs (Avast! for example). Also, Skype does not connect either. Apparently only IE can connect to the internet. Could this be a particular malware/virus? It all happened all of a sudden and I didn’t change any internet settings recently.[/FONT]
 
You may be correct. You have three browsers and IE still works. Let's determine if Opera was corrupted.
Under Control Panel->Programs, find Opera and start to uninstall it. *IF* you are given a REPAIR option, try that first. Otherwise, do the uninstall, get a fresh copy and then reinstall.
 
Sorry man - - I'm at the end of my rope - - sure wish I could have solved this for you.
Look at it this way - - this thread is good documentation.

Hopefully you have backups of your Documents + Pictures (don't try to recover anything other than those).
