When I attempt to download the DAB podcast, I receive and error about my network connection.

Usually if you receive a network-connection error, it is usually specific to an individual or a small group of people.

01. See if your other podcasts are downloading or if other internet applications are working. Try restarting both iTunes and your computer. If none of your podcasts work, it’s likely a problem with your Internet service provider.

02. See if the podcast plays from the direct link: http://feeds2.feedburner.com/dailyaudiobible If it does, that probably indicates that everything is up and running from the DAB-end. Try unsubscribing and resubscribing from the podcast at iTunes.

03. Make sure you have the latest version of iTunes: http://www.apple.com/iTunes/download/

04. It may be necessary to clear your DNS cache. Another common reason why you might be able to connect to some websites but not others is due to incorrect Domain Name Server (DNS) settings. Clearing your DNS Cache may resolve the issue and enable you to connect to the iTunes Store.

The easiest way to clear your DNS Cache is to shut down your system completely and then restart. If shutting down is not an option, you can also clear your DNS cache manually.

To clear your DNS cache manually:
Step 1: Click Start and choose Run.
Step 2: In the dialog that appears, type "cmd" (don't type the quotes) and click OK.
Step 3: After the DOS prompt (C:\), type "ipconfig /flushdns" (without the quotes) and press Enter. Make sure you enter a single blank space after "ipconfig."

The DNS settings your Internet connection uses are provided by your Internet Service Provider (ISP). If clearing the cache using the above steps still doesn't resolve the issue, you may want to contact your ISP and verify your DNS settings.
