iPod Software Update Server can not be contacted

I have a vintage iPod Mini that I am attempting to Restore on a iMac PPC with iTunes 9. When I select the Restore button in iTunes, a dialog box appears stating that the iPod Update Server can not be contacted. Resolutions from the iTunes Help relate only to Windows based Operating Systems. Other discussions all relate to Windows Regarding Macs; it states that I should check my internet settings to make sure I can contact an Apple site and clearly as you can see, I can create a discussion topic, so it is not the internet.

Can anyone offer a resolution to this problem
