Now I find that my Emacs server start hangs after processing my .emacs file but before creating the server socket (it creates the directory used to store the socket information file, but the file itself is not created).

I wouldn't expect this to work, because of the '&'.  Here's what I see when I run that command interactively:

$ emacsclient -n -c --alternate-editor=""&
[1] 10404

$ ps
      PID    PPID    PGID     WINPID   TTY         UID    STIME COMMAND
[...]
S   10404    6660   10404       9300  pty0      197609 14:21:41 /usr/bin/emacsclient-X11

Putting emacsclient in the foreground makes it run as expected:

$ fg
emacsclient -n -c --alternate-editor=""
emacsclient: can't find socket; have you started the server?
To start the server in Emacs, type "M-x server-start".

Emacs daemon should have started, trying to connect again

And just running emacsclient in the foreground to begin with also works as expected for me.

This works fine for me also:

$ emacs-w32 --daemon -q
Starting Emacs daemon.

Your cygcheck output shows two cygwin1.dlls in your path:

Warning: There are multiple cygwin1.dlls on your path

I don't know if this could cause the problems you're seeing, but could you try removing \\a1\utils from your path and see if that helps?
