I'm unable to reproduce the issue, but I'm a little unsure I have the
complete list of steps to do so. Let's start with these questions:
Is your system part of a Windows domain?
How exactly are you starting cygserver?
When you say "each new session" do you mean opening a new Cygwin
Terminal that presents the usual bash+mintty user CLI? Or is it some
other method?
