--- Comment #19 from Sidney Markowitz <sid...@sidney.com> --- I've uploaded a test build that will use 1.1.1.1 for the nameserver on Windows for those four tests. It isn't a correct solution, but it will at least check if the problem has something to do with the nameserver on the local subnet that those Windows test machines are configured to use. If that works, perhaps we need to figure out how to retry on a different nameserver after receiving an error result. -- You are receiving this mail because: You are the assignee for the bug.
