    Mac OS X Server 10.5: Troubleshooting CalDAV

    I originally posted this at http://www.318.com/TechJournal So you installed your new server and you’re having a few problems. Let’s look at the common issues and a few simple fixes for them. iCal will not start, with log entries that it is unable to create a virtual host: Check your host name. iCal is going to need the host name to be correct in order to start.
