Normally, for Specialists that are installing their SharePoint 2010 Demo environments, so as to demonstrate custom solutions to clients, they usually do their installations onto their machines (Laptops) that in most cases are connected to their company domains. So what happens when the Specialist goes home or is at a client site is that, their SharePoint 2010 Search fails to return any results, and the wonder why this is so when not only are there no errors being registered but they also have full permissions on anything they can think of, after all, they did the installation themselves using an account with admin privileges. ;)
