multiple users sharing ssh_host keys on winxp

Hi,

I just got my sshd working for a user on winxp, problem is that my
username has a "space" in it so it causes problems when i try to ssh
into my acct. my username is : Joanna Ho

So, i created a new user w/ no spaces w/ administrative priveleges just
like my user mentioned above so that i can ssh into this user called
"joanna"

in "joanna" when i type:

/usr/sbin/sshd.exe i get:

could not load host key: /etc/ssh_host_key
could not load host key:/etc/ssh_host_rsa_key
could not load host key:/etc/ssh_host_dsa_key
disabling protocol version 1. could not load host key
disabling protocol version 2. could not load host key
sshd: no hostkeys available -- exiting


i tried changing my permissions of my ssh_host_keys in my Joanna Ho
acct. so that they are executable by other users, however, although i
have 711 permissions, it still lists under category :

-rwx--x--x--- 1 Joanna Ho None 540 Dec 21 22:09 ssh_host_dsa_key

im not sure if the "none" is a problem. i can't change this "none" to
users i dont' think you can do this under xp.

any comments would be appreciated.

Thanks.
