>Security issue? Does the account you're logged in as have privileges to view that database? Are there new security settings in SQL2005 that need to be checked?

It's probably something related to that. I am logged as the same account as in the VS 2005 interface. The database is setup to Use Windows Autentication. If from the VS 2005 interface, I do a test by changing to Use SQL Server Authentication, my test connection returns that the user is not associated with a trusted SQL Server connection. Basically, on this first test, I do not want to assign any specific privileges to this database. I want to make it as simple as possible.
