internet explorer connection

running an acer l36oo o/s vista premium ,virgin isp,computer 12 weeks old upto date with up dates running ok, now cannot connect to internet error message {res://ieframe.dll/dnserror.htm# } bottom left had corner.can only connect to internet by setting up systems restore point 5 days back every time i need the internet ,can only contact acer 9 to 5 very difficult during week , any ideas very wellcome thanks barrie.

I doubt if Acer will be able to help as you have a software rather than a hardware problem. If System Restore fixes your problem temporarily but the fix does not last then you must be making the same mistake over and over again.

An obvious sort of mistake would be running your computer without adequate security software, thereby allowing malware to compromise your settings. What security software are you using?

A possible workaround is to use a different web browser. Try downloading and installing Google Chrome and see if that works. You will have to do this whilst Internet Explorer is working.

running bullguard 8.5 anti virus plus regcure, computer cleaned each week, modem working ,router working,computer upstairs working fine{wireless upstairs]problem computer wired, even tried with firewall off no luck on connection unless i use system restore point.very carefulabout computer use, just used for surfing, and emails.used bullguard ,and regcure on both computers never had any problems before .

Hi Barrie,
Is it only your browser that stops working? Do you have some other internet enabled program installed that you could use to verify whether only Internet Explorer is blocked? I'm thinking of Google Earth or Outlook Express etc.

You should run this command from a command prompt:

ipconfig /all

to verify that you have a valid IP address on your wired LAN connection. It will typically be 192.168.X.Y where X and Y are numbers between 1 and 254

You should also see a Gateway Address with a similar number.

At the command prompt try typing these commands:

ping eg. ping 192.168.1.3

You should get 4 replies

ping eg ping 192.168.1.1

You should get 4 replies

ping bbc.co.uk

You should get 4 replies

It could be that you've disabled Windows firewall but Bulldog firewall is blocking Internet Exploerer explicitly. Let us know how you get on.

Hi Dave, switched computer off and restarted to see if connection works the computer went into system restore on its own and restored itself!!!.
Google chrome working ok but have lost two account users off the computer completely, only the administrators account left.Will try what you just posted in a minute. Not sure how to run the prompt on vista this is a new operating system to me.

I wonder if you have a faulty hard drive? That could cause the spontaneous System Restore on start-up.

Or it could be a virus. I'm not sure Bullguard is the best at finding malware, try an online scan with a company like Kaspersky.

I don't trust Registry cleaners either. Could it be you always have to restore to before you last ran Regcure?

On Vista the quickest way to load a cmd prompt is to enter cmd in the search box at the bottom left of the start window. But Dave didn't explain himself very well; you will only get a response from 192.168.1.Y if X=1 and Y is present on your network.

connection seems ok computer seems to have restored itself to out of box status internet explorer7.0 default browser also using google chrome[like it fast and straight foward] have restored users,bit concerned about updates putting back to how it was , going to try kaspersky can recommend something better than reg cure, many thanks to all who helped . barrie.

Sorry all, my post got mangled by the markup parser of the website. I had written something along the lines of:

ping myaddress ---bigspace--- eg ping 192.168.1.3

with myaddress in angle brackets - but they and their content got omitted completely - similar problem for the gateway.

DON'T use regcure - it will **** your machine/ Only the paid-for version works, and even then sparingly. In my opionion Regcure is useless and has no place on a computer. The ONLY registry cleaner I will use is CCleaner - but you are using Vista, and so you do not need a reg cleaner. The Vista registry loads in a different way so that redundant stuff does not get called
Bullguard in my experience has issues. I can't say more than that for fear of legal issues, but I would advise Kaspersky as the best protection package.
It sounds to me as if you have a major infection which is messing you winsock/DNS settings. System restore fixes these for a short while but does not remove the infection - it simply reloads and recreates the issue
Personally I would reload the machine to factory settings, put a real security product such as Kaspersky IS on it, and then run all the windows updates

I had a similar problem with someone elses computer I was fixing. It turned out that they had about 5 firewalls, and the same amount of anti-viruses on the computer, and then installed AVG on top of all that.

With that amount of firewalls they'd totally killed the internet connection as too many were competing against each other.

Best thing to do is as the other guy stated, run cmd (in Vista type cmd in the search box and click on it when it appears at the top of the start menu). Then type ipconfig to check your ipconfig (also in Vista if your ip is ok you should have a little icon in the bottom right hand corner of the screen with a world on it, no world not internet connection).

If your ip address looks fine, if your going through a router it normally starts 192.168, or if your going straight through Virgin it might start eighty something. If Windows is coming up with "limited or no connectivity" error this is because Windows is using it's own local ip address, which only has one computer on it and loops back on itself.

Then try pinging to see where you get first and best place to try is to look through the IPConfig read out and pick the "default gateway" line - e.g. 192.168.1.1 - type ping 192.168.1.1 (replace 192.168.1.1 with your default gateway)

If you get responses from that then you know your system can reach the gateway, next try pinging somewhere that is normally always available I always use google as the response is usually really fast so type ping www.google.co.uk if that comes back ok then check your internet settings.

Go into control panel and find internet options (it's called internet options in Classic View, it's in Network and Internet Connections in Category view), or if you can't find it in control panel load up Internet Explorer (not Firefox or Google Chrome) and click the tools menu and internet options (nb. if you can't find internet explorer open up My Computer and type a web address into the address bar, this turn Explorer into Internet Explorer)

Go to the connections tab and if your on Virgin or have internet through a router make sure that it's set to "Never dial a connection", click LAN settings and put a tick in "Automatically detect settings", make sure no other boxes are ticked in there especially the one that says "Use a proxy server", if this is ticked there could be a chance you have a virus or adware on your system that has changed your settings. Click OK and try and access the internet.

If this doesn't work then start looking into turning your firewalls off, one by one turn your protection off and keep pressing reload on your browser, until eventually you find the one thing that is blocking it (also turn your anti-viruses off as well) - and don't forget about Windows Firewall as well. As your turning the firewalls and anti-virus off you will get numerous warnings about "are you really sure you want to do this, it could be dangerous to your system" just say Yes to each one, they are right it could be dangerous to your system but as we're only going to be loading up a web page like google for five minutes to eliminate the problem it's not going to put the computer at serious risk, unless there already is a virus on the computer, but if you already have a virus on there your already at risk as most viruses are programmed to disrupt anti-virus programs and firewalls anyway. Once you've found out which program is causing the problem remove it and go to the official website of the program maker and try and download a new version of it from them and re-install (you also might want to check the hash code (if possible) of the program you download to ensure you are getting a genuine non-tampered with version of the program). If it does the same again look for some other way to protect your computer. Also I recommend that you should only have one firewall and one anti-virus on your system, numerous firewalls and anti-virus programs do reduce your risk of being attacked, but they can also lead to major problems when they start conflicting with each other. I use ESET System Security, which is possibly the best and least intrusive antivirus and firewall I've found. Also one other major important thing is if you bought your computer from any major PC retailer, like Dell, Compaq, HP, PC World, etc if it come with a "free trial" of Norton and you have installed another anti-virus or firewall on your computer after your free trial run out and thought you'd uninstalled Norton it most probably is still on your system. The best way to ensure Norton has gone if you want to use a rival Antivirus is to search Google for Norton Removal Tool and remove it with this, Norton's uninstaller and add/remove programs most of the time is hopeless.

trouble is all that will just treat the symptoms, not the cause
From what barrie has said I believe there is a deep-seated viral problem, and maybe also a hardware fault. His last posting where he said the machine had appeared to revert to its original settings suggested corrupt registry files - either due to faulty memory or hard drive
If its faulty it needs to go back. And to prove whether thats the case it needs reloading to factory settings, if the symptoms persist then Acer cannot refuse an RMA
Also reloading it would resolve any viral issues as well
