Yes. I'm just wondering if we shouldn't check for the Admins group
only. The token of the SYSTEM user always contains the Admins group and
the cyg_server (or whatever the name is) user is always (and should
always) be created as member of the admins group, too. So, if I didn't
miss anything important, the check could be reduced to checking for the
admins group permissions. Does that make sense?
