Cool! Look at the date! So I did it again wrong after you already
fixed it in 2002. Oh well. Btw, I tested this today and it seems the
patch is working. I'll just change it to use a well_known_builtin_sid
rather than creating the SID on the fly.

I have no idea, sorry. The Win32 error 6 is an invalid handle. But the
token used here is always an impersonation token, just as AccessCheck
