wp-admin and .htaccess file help

OK, I must be missing something really simple here. I have a very basic .htaccess file in my /wp-admin/ folder. With this .htaccess file there I get the wordpress 404 page when trying to access any dashboard or admin interface page.

I’d really like suggestions on what’s causing this. Here is the .htaccess file in my wp-admin folder:

order allow deny
deny from all
allow from zz.zzz.zzz.zzz (IP I use)
allow from zz.zzz.zzz.zzz (IP I use)
AuthType Basic
AuthName “wp-admin”
AuthUserFile “/home/zzzzzzz/.htpasswds/public_html/wp-admin/passwd”
require valid-user

And I also have a .htaccess in my web root that’s pretty basic too:

<Files 403.shtml>
order allow,deny
allow from all
</Files>

deny from 2.88.121.97 (leaving ip kuz they are jerks)
deny from 2.88.0.0/16 (leaving ip kuz they are jerks)
