Well, the error message is quite self-explaining. Have you debug to find out where is breaking?

With that few information, we can not do much. Please read:

Check your connection string, paying particular attention to the Integrated Security or User ID and Password sections.

The former is normally only used for development, the later is almost always used for production. The latter requires fully valid id and password, so double check those against the data you were given by the DBA.
