Thanks both of you, I'll look at both these and see what comes up on the machines that are causing issues. My fallback position is to make the test operator provide a settings file with their FQDN when using longnames configurations, which at least minimises the impact, but still it'd be nice to do this without forcing the user to intervene. I will post back to the list if/when I find out the best approach for my own particular use case.

Cheers!
