When connecting through the SQLOLEDB provider use the syntax Network Library=dbmssocnand when connecting through MSDASQL provider use the syntax Network=dbmssocn All SqlConnection connection string propertiesThis table shows all connection string properties for the ADO.NET SqlConnection object. Most of the properties are also used in ADO. All properties and descriptions is from msdn. NameDefaultDescriptionApplication NameThe name of the application, or '.Net SqlClient Data Provider' if no application name is provided.AttachDBFilename-or-extended;properties-or-Initial File NameThe name of the primary file, including the full path name, of an attachable database. The database name must be specified with the keyword 'database'.Connect Timeout-or-Connection Timeout15The length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error.Connection Lifetime0When a connection is returned to the pool, its creation time is compared with the current time, and the connection is destroyed if that time span (in seconds) exceeds the value specified by connection lifetime. Useful in clustered configurations to force load balancing between a running server and a server just brought on-line.Connection Reset'true'Determines whether the database connection is reset when being removed from the pool. Setting to 'false' avoids making an additional server round-trip when obtaining a connection, but the programmer must be aware that the connection state is not being reset.Current LanguageThe SQL Server Language record name.Data Source-or-Server-or-Address-or-Addr-or-Network AddressThe name or network address of the instance of SQL Server to which to connect.Enlist'true'When true, the pooler automatically enlists the connection in the creation thread's current transaction context.Initial Catalog-or-DatabaseThe name of the database.Integrated Security-or-Trusted_Connection'false'Whether the connection is to be a secure connection or not. Recognized values are 'true', 'false', and 'sspi', which is equivalent to 'true'.Max Pool Size100The maximum number of connections allowed in the pool.Min Pool Size0The minimum number of connections allowed in the pool.Network Library-or-Net'dbmssocn'The network library used to establish a connection to an instance of SQL Server. Supported values include dbnmpntw (Named Pipes), dbmsrpcn (Multiprotocol), dbmsadsn (Apple Talk), dbmsgnet (VIA), dbmsipcn (Shared Memory) and dbmsspxn (IPX/SPX), and dbmssocn (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.Packet Size8192Size in bytes of the network packets used to communicate with an instance of SQL Server.Password-or-PwdThe password for the SQL Server account logging on.Persist Security Info'false'When set to 'false', security-sensitive 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.Pooling'true'When true, the SQLConnection object is drawn from the appropriate pool, or if necessary, is created and added to the appropriate pool.User IDThe SQL Server login account.Workstation IDthe local computer nameThe name of the workstation connecting to SQL Server.Note Use ; to separate each property.If a name occurs more than once, the value from the last one in the connection string will be used.If you are building your connection string in your app using values from user input fields, make sure the user can't change the connection string by inserting an additional property with another value within the user value.

Use the .NET Framework Data Provider for SQL Server (SqlConnection). COM applications, all other then .Net applicationsUse the SQL Native Client if you are accessing an SQL Server 2005 and need the new features of SQL Server 2005 such as MARS, encryption, XML data type etc. Continue use your current provider (OLE DB / ODBC through the MDAC package) if you are not connecting to an SQL Server 2005 (that's quite obvious eh..) or if you are connecting to an SQL Server 2005 but are not using any of the new SQL Server 2005 features.
