Andrey and myself are trying to point you towards solving your problem, which appears to be from your Windows network profile, which is set up by your Windows support team, and is broken under your upgraded release. You need to contact your corporate Windows support team and have them help to fix your profile problem. You can try to do so yourself by renaming your profile folder and immediately restarting your system. You will of course lose your settings, but this is a standard corporate Windows support approach, as is reimaging your system. To that end, restoring your system, by rolling back the upgrade, to its pre-upgrade state, would also be a viable approach for you to try. We are unconcerned about blame, only pointing at the likely cause, and your denial that anything can be done about your broken profile settings. >> But if your work infrastructure does not yet support W10 1809 (do you >> really mean that release, not the current 1909 release?) you should not >> have upgraded, and any breakage is down to you. > > Again, you took this as me trying to assign blame, which is pointless. > > Yes, I meant 1809, and although I performed the upgrade manually, it would > have been done automatically in the near future if I hadn't, so there was > no choice there. Your corporate upgrade would have been applied using a different approach, with relevant settings saved and restored, or replaced in a way compatible with your corporate environment. A lot of work and testing is done by corporate Windows support groups to minimize problems and their subsequent support load after upgrades. >> For Cygwin options see: >> >> https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping-nsswitch-desc > > Yes, I've seen that, and considered my options there, but I don't think > that will address this situation.

That section shows how to override HOME under Cygwin using an XML like SAM Comment: $ net user $USER /comment:"" which may need some extra quoting to get the quotes into the comment: you may then symlink your effective home directory to /home/$USER. The docs are available locally if you install cygwin-doc and use: $ cygstart /usr/share/doc/cygwin-doc/html/cygwin-ug-net/ntsec.html but cygstart does not support fragments in file URLs. -- Take care.
