Chris,

You shouldn't need to copy your DLL to another directory. The bin directory off of the root virtual directory is where it should be read from. Are you only using one virtual directory or have you setup different ones for each sub-directory?

For the deny users statement, make sure the valid users are listed first in the web.config. Make sure you are placing the authentication information in the we.config in the root directoy. You can not use web.config files in sub-folders for authentication.
