emacsclient works fine when I unset the environment variable  
"EMACS_SERVER_FILE". This holds true regardless what server-auth-dir  
is set to.

In order to produce the error, do the following:

(1) start emacs -Q.
(2) execute in the scratch buffer
       (require 'server)

       (setq server-auth-dir "~/")

       (server-start)

(3) go to a cygwin bash (outside emacs)

(4) set EMACS_SERVER_FILE to "~/server"

(5) run the command

       emacsclient ~/.emacs

and you get the error message from the original post, but you'd expect  
to get in emacs a buffer displayed with the .emasc file.
