I did a clean install on Standard Server on a to-spec Mac, on a small Airport network with the intent to share files, iCal and VPN for outsiders to access via their macs. I've not set up my Asante router yet (Airport is plugged into it), however I can easily access the server via AFP & it shows beautifully in my finder. However, I can't connect via iCal - I get this error. I suspect I named my server incorrectly with a .private. The error I get is: SERVER IS UNREACHABLE OR ITS NAME IS NOT VALID. I'm pretty clueless about how DNS works, even after watching the Lynda.com movies a few times and reading the manual. I know, I'm too busy running my business! Can anyone suggest a fix?
