SWF on a different server

1. I have a swf on server (A).
2. It is being called on server (B).
3. There is a URL link button on the swf.
4. I created a html file and put it on server (A) and the swf link works.
5. When I call the movie from server (B) the movie loads but the link does not work.

Can anyone help. Much appreciated.

Thanks.
