> Sorry...  Did you try using the -d option to see what DNS servers these commands try to actually connect to (and time out, eventually).

No help unfortunately.

$ host -d6 cygwin.com
Trying "cygwin.com"
;; connection timed out; no servers could be reached

Posted at https://pastebin.com/XWwxJ41b. I'm not able to make much sense of it,
except that on line 1339, I waited almost 5 seconds for sendmsg:

4964291 6958349 [isc-worker0000] host 20999 cygwin_sendmsg: 28 = sendmsg(20,
0x7FFDFC830, 0x0)

Thanks for taking a look. I'm looking at other options in resolv.conf, but
haven't found anything useful.

I can't find any documention of the osquery option. This answer[1] says
"res_init() uses the Windows resolver if either /etc/resolv.conf does not exist,
or /etc/resolv.conf contains options osquery." Doesn't help in this case though.
