Answer: If the database was previously attached, SQL Server does not reattach it (it uses the attached database as the default for the connection).Download the SQL Native Client here (the package contains booth the ODBC driver and the OLE DB provider)Using SQL Server 2005 Express?

Note Use 。, securitysensitive information, such as the password, is not returned as part of the connection if the connection is open or has ever been in an open state. Resetting the connection string resets all connection string values including the password.

Supported values include dbnmpntw (Named Pipes), dbmsrp (Multiprotocol), dbmsadsn (Apple Talk), dbmsgnet (VIA), dbmsip (Shared Memory) and dbmsspxn (IPX/SPX), and dbmsso (TCP/IP). The corresponding network DLL must be installed on the system to which you connect. If you do not specify a network and you use a local server (for example, . or (local)), shared memory is used.
