Well, at least then I know that it is a connectivity problem and 
not a strict authorisation problem.

Could you try changing the server name to something absolutely

Are you using Windows authentication or SQL authentication?

Sorry for all the question, but troubleshooting connectivity problems on 
a distance with a minimum of information is tedious.
