SQL Install – No Mapping Between Account Names and Security IDs

Working on a test virtual install of SharePoint 2010, an interesting error on installing SQL 2008 R2, “No Mapping Between Account Names and Security IDs”. Turns out I was dumb in re-using a server image which hadn’t been sysprep’d with the generalise option.
