CKG Edit ====== ====== ===== Concept ===== DNS (Domain Name System) is a way of giving a computer a more human name. Computers resolve DNS addresses like //www.google.com// and //CyriousServer// into addresses so that network traffic can go there. Computer can resolve the addresses locally (for other computers on their network) or using a DNS Server (usually used for internet addresses). Since looking up an address can take as much time as accessing what is needed, the computer stores, or //caches//, the computer-friendly address that goes with the DNS. Your computer will retain this address for a certain amount of time before looking it up again if needed. (Usually this ranges is 30 minutes to a few hours, depending on the system.) This error resets (flushes) the DNS Cache on your computer. It is used when you suspect the computer may have problems finding another computer because something about the routing of information to that computer has changed since it last looked up the address. Please Note: The above is an over-simple model that is not 100% correct. But unless you are going to design routing and addressing systems it is as much as you will ever need. ===== Steps ===== - Flush the DNS Resolver Cache - Go to Start > Run and type CMD to launch the command prompt. - Type ipconfig /flushdns - If successful then thats it this is not the problem computer so keep going to the next computer. However if you recieve an error saying could not flush the DNS Resolved Cache: Function failed during execution", this is how you fix it. ### Go to Start > Run and type services.msc. Double click the DNS client to bring up the DNS properties Window. Make sure the Startup Type is set to automatic, and service status is Started. If it is not click the drop down arrow and select Automatic and click the start button. ### Finally Run the ipconfig /flushdns again as listed above and you should see "Successfully Flushed the DNS Resolver Cache." ===== Version Information ===== * Reported : 7/2009 * Version(s): All
