Troubleshooting Vista Browsing Issues
Have you ever had an issue where you continually get DNS errors when trying to browse the Internet with one Windows Vista computer, but another computer on the same network works just fine? If you have, you know how frustrating that can be! Well, more than likely, the problem is you need to reload your DNS cache on the computer that’s not working. I know that may sound a little difficult, but if you keep reading, I’ll walk you through it all!
You can tackle the problem in two ways. You can either just clear out the cache or simply restart the DNS client service, which handles the caching of DNS lockups. I’ll tell you how to do both and you can then decide which one will work the best for you!
Clearing the DNS Cache
Open an Administrator mode command prompt by right clicking on the Command Prompt option in the Start menu. Then select Run as Administrator.
Now, type in the following command: ipconfig /flushdns
That usually clears up any issues that might be occurring. Note that if you’re using Firefox, you should probably close and reopen it, because Firefox has a DNS cache of its own as well.
Restarting the DNS Service from a Command Line
Open an Administrator mode command prompt (just like you did before) and then type in the following commands: net stop dnscache and net start dnscache.
I usually use the command prompt for this, since I already have it open from the previous step.
Restarting the DNS Service from Services
Go to Start, Control Panel and select Services. Once you’re there, find the DNS Client service and click on the Restart Service button.
By this point, everything should be working again. Note that these instructions should also work for Windows XP. I hope this one helps you all out a great deal!
