Of course it has "something to do with Cygwin", because I'm using it, and Cygwin and WIndows are using a shared resource, the "HOME" variable. Cygwin and Windows try to use it for different purposes. There's nothing I can do about the "Windows network profile". > 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. > 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. The problem is the contents of the "HOME" variable. It doesn't matter where my Cygwin HOME directory actually resides.
