having no experience whatsoever in this, my first thought is, does the \ 
need to be escaped?

It looks like sudo thinks of you as DOMAIN\windows.username

You could try running sudo through strace to see what that may tell you.

Also, it looks like %foo refers to a group not a user.  From the brief 
searching of the web, it looks like the common approach is to tell sudo 
to trust a group that you are a member of (if possible, a group that 
only you are a member of).

%mygroup ALL=(ALL) ALL
