DNS/Minires problems w/ Exim-4.20 on Cygwin

[RUBiK <rub1k at yahoo dot com>]

Hello-

I am writing to you as a last attempt to perhaps help solve the problems I
am having with exim (4.20-1) on Cygwin (1.3.22-1) on WinXP Pro SP1.

I have been using Cygwin for a long time but just recently tried setting
up exim and ran into problems.  I've followed the
/usr/doc/Cygwin/exim-4.20-1.README instructions and installed exim as a
service with ntsec and all went well.

However, no matter what I have tried (even recompiled the patched source
myself), I am not able to resolve *any* remote domain via exim, even
though nslookup and/or dig do work.

I have tried endless Google searches and have read through many mailing
lists, etc. but I've found nothing specific.

Here is a debug log of one query (all queries for all remote hosts return
the same "Error 2. Count 0."/TRY_AGAIN status):

$ exim -d+dns+resolver -c -bt rub1k@yahoo.com > eximout.txt 2>&1
