I have a .Net web application compiled on my PC using the Framework version 1.0. Then install it to a Windows Server 2003 server (with Framework version 1.1). Then I have these two errors when trying to make database (Oracle) connection:
1-Exception Details: System.IO.FileNotFoundException: File or assembly name System.Data.OracleClient, or one of its dependencies, was not found.
2-Exception Details: System.Data.OleDb.OleDbException: No error information available: 0x800401F9.

Does anybody have any ideas about that?
