Billy,
That's really strange. Maybe you can try popping into your NAS's web interface by going into your web browser, and punching in your IP address through the browser?
If you haven't set up access for it yet or haven't been there before, it should be admin as the username, and no password.
Here's the manual: http://www.dlink.ua/sites/default/files/DNS-325...
Refer to page 214 (in the PDF itself, the PDF reader will pick it up as page 219) and see if you can enable anonymous access as the login method under Local Backups.
