Sorry, I cannot reproduce this, even with all my Cygwin processes stopped
prior to running this:

C:\>set HOME=c:\users\lhall

C:\>ssh -v ds9
OpenSSH_5.8p1, OpenSSL 0.9.8r 8 Feb 2011
debug1: Reading configuration data /etc/ssh_config
debug1: Connecting to ds9 [192.168.1.190] port 22.
debug1: Connection established.
debug1: identity file /home/lhall/.ssh/id_rsa type 1
...
(succeeds)

But looking back at your '/etc/passwd' entry, you have:

tda:unused_by_nt/2000/xp:1000:513:U-laptop1\tda,S-1-5-21-2414507100-3802266639-3593817948-1000:/home/tda:/bin/bash

When I compare that to the home directory you want (HOME=c:\Users\tda.DCA),
I'm wondering if you have a mismatch of usernames.  What does 'id' tell
you your user is?

Also, I note that our debug output for 'ssh -v' differs.  You may want to
investigate that some too.

Other stray ideas which may or may not be relevant:
   BLODA
   Downgrade OpenSSH
