I have Vista Home Premium (x64) machine at home. I have www.google.pl set up as my default search engine in IE8.
Sometimes (since one month or so) when I search for something IE gives me "dns error" message and it cannot find www.goole.pl for 10-15 minutes. Frequency: 1-2 times/day. In the same time I checked google.pl on my PlayStation and it's working correctly Sometimes google.com and live.com is not working also.
I have router which I installed few years ago and didn't changed nothing in it since then, so I excluded it as a reason.
After short search on internet I found that nslookup is working without any problem, but ping is not.
When I've try
ping -4 www.google.pl the problem dissapears until next time. This is why I think it's a problem with IPv6 and that somehow my Vista is using IPv6 even if it's not working.
I called my ISP but they claim that nothing was changed in their dns and I should search for a problem on my machine.
Yesterday my neighbour - which is using the same ISP - told me that he has the same problem with his Vista (x32), but thought it's google problem. When we talked he admitted that his machine with XP doesn't have any problems
- Is it problem with my machine or my ISP?
- If it's my machine - how can I find the reason and fix it?
- If it's my ISP - how can I prove it to them?
