be a useful tool to resolve any host connection errors that you may experience with Google Chrome or other browsers. It is very simple to do dns resolver cache ttl and can be done directly in Chrome or from an Elevated Command Prompt window in Windows 7 or 8. What is the DNS Cache? Your browser’s DNS Cache (Domain Name System) is essentially a small databank that stores all the IP (Internet Protocol) addresses

for websites you access. The main purpose of this database is to make it easier for your computer to reach and access the IP addresses of websites when their servers change or if they create new servers. When IP addresses become outdated or if a website switches to a new server, you may encounter DNS errors when you try to access them. Sometimes, due to continued use and accessing sites with a less than perfect web safety rating, your DNS cache may also become corrupted. This is where dns resolver cache linux a DNS cache flush comes in handy. What is Flushing? Just like flushing a toilet and getting rid of any old water that is stored in the tank, a DNS flush will make your computer erase any existing information regarding DNS names and IP addresses that is has stored. After you perform a flush, the next time you try to access a website, your computer will ask for all the new IP and DNS information related to that site resulting in an error free browsing experience. Flushing your Cache through Google Chrome If you experience any DNS or host error related browsing issues, it can sometimes help to perform a DNS and Socket flush using your Google Chrome browser. In order to fix these problems, follow these simple steps. Begin by opening Google Chrome and type in this address: chrome://net-internals/#dns and press “Enter.” If you look at our screenshot, you will notice that there are 24 active entries and a list with details of all the IP addresses that the DNS cache has picked up and stored. In order to flush your Google Chrome browser’s DNS cache, simply find the button that says “Clear Host Cache” and click it. You can click it more than once if you want to make sure it did what it was supposed to, but a single click is usually enough. You will notice that the number of active entries has gone down to 0 and the list of websites accessed has been cleared. The next step will be to flush all the Sockets by navigating to

Well, I contacted myself, but I wasn't home :P I tried flushing the DNS cache manually by going through the Start > dns resolver Run... > CMD > ipconfig /flushdns approach, but I received yet another error: "Could not flush the DNS Resolver Cache: Function failed during execution." I also read Microsoft's solution to the problem, but it didn't work. They suggested that my DNS Client service was not running, but it was/is - and I've tried restarting the service, restarting the system, rebooting my router, and wiggling dns resolver cache the power cable. Nada. Any ideas? Cheers. Paddy 6 219 posts since Sep 2004 Community Member windows-nt-2000-xp Ask a Different Question 0 shanebrown 10 Years Ago Hi Paddy I have been having exactly the same problem. Did you managed to resolve your problem? regards Shane 0 Discussion Starter Paddy 6 10 Years Ago Sorry man, I haven't been able to fix it. If anyone else on the forum would like to pitch in, Shane and I would be very grateful! :) 0 MartyMcFly 9 10 Years Ago Hi What address have you for DNS. You said you have router, is that an ADSL Router? If so, try setting the IP to the Router IP, or loopback address 127.0.0.1 GL, David 0 Discussion Starter Paddy 6 10 Years Ago Hello Marty ;) Yes, it is an ADSL router. I have set up a static IP address for the purposes of port forwarding, although my actual WAN IP is dynamic. Now, when you say that I should set the IP to match the router's IP, which IP do you mean? Do you mean that I go into the internet connection settings and then
have been looked up recently. (For more detail on how Internet addresses work, see this article.) Once an URL has been resolved by an Internet name server into a numerical IP, the information is stored locally. Anytime your browser requests an URL, Windows first looks in the local cache to see if it is there before querying the external name server used by your ISP. If it finds the resolved URL locally it uses that IP. This is supposed to save time and cut down on Web traffic Clear the DNS resolver cache A problem can arise if the IP for an URL changes or the DNS entry gets corrupted while it is still stored in the local cache. In this case an error message will result if you try to connect to the URL. It is not a frequent occurrence but is not unknown. Fortunately, it is possible to clear out the local DNS cache in order to get around these types of problems. All current versions of Windows come with a useful command-line utility ipconfig (discussed here) that has a switch, flushdns, for removing the entries in the cache. Open a command prompt and enteripconfig /flushdnsand the cache will emptied. (In Windows Vista and Windows 7, it will be necessary to use the command line with elevated privileges.) Personally, I find that it sometimes speeds up Internet browsing to do this flush even when there are no obvious error messages. If you are curious about the contents of the DNS cache, they can be seen by using another switch with ipconfig. In this case open a command prompt and enteripconfig /displaydns Also, if you are experiencing trouble connecting to a particular Web site, it may be useful to see if its URL is in the cache and what IP is being used. Configure the DNS resolver cache in Windows XP According to Microsoft, Windows XP keeps IPs in the DNS cache for a default time of 86,400 seconds or one day. (Various web browsers may actually use a shorter time.) This time period can be changed by reducing the Time to Live or TTL. This requires a Registry edit so should be done only by those who know how to restore their Registry. The Registry key that is involved is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNSCache\Parameters The DWORD value MaxCacheTtl can be used to control how long positive responses are kept. This DWORD is normally missing and the default value is used. If you wish to change the TTL, create the entry and enter your preferred time in seconds. Most PC users will probably not gain much this way, however. Negative responses are another story. There is a default DNS caching of negative results for fifteen minutes, which would be neither convenient nor necessary. I often encount
