VMware Standalone Converter 5.5 fails conversion with vim.fault.NonAuthenitcated

During an overnight conversion of a large virtual machine from an old ESX 3.0.2 server to a new ESXi 5.5 server. The conversion failed at 19% with error vim.fault.NonAuthenitcated

After some googling, not much showed up. Took a flyer and retired the job, it completed!!

If at first you don't succeed, try , try and try again. :)
