I cannot reproduce this on MS-Windows.  When I try the above, Emacs
first tries to connect to a local server:

  Opening connection to localhost:2628

Then it says:

  Failed to open server localhost, continue with dict.org? (y or n)

I answer 'y', and then:

  Opening connection to dict.org:2628
  Searching for Hello in *

and next I see 4 definitions it finds.

So I wonder what goes wrong in your case.  Is your Internet connection
working on the Windows machine? is port 2628 blocked by some firewall,
per chance?
