Especially when after just one getaddrinfo call, the DNS cache is populated
with:
leapsecond.utcd.org
----------------------------------------
Record Name . . . . . : leapsecond.utcd.org
Record Type . . . . . : 1
Time To Live . . . . : 600
Data Length . . . . . : 4
Section . . . . . . . : Answer
A (Host) Record . . . : 244.34.36.97
so the DNS server is being contacted and responding normally, but it would
appear Windows GAI is failing to use that info.
Has this been reproduced on W10 so we can report this upstream?
Is there any support without an account for upstream W7 reports?
