When connecting through the SQLOLEDB provider use the syntax Network Library=dbmssocn
and when connecting through MSDASQL provider use the syntax Network=dbmssocn

- All SqlConnection connectionstring properties
- This table shows all connectionstring properties for the SqlConnection . Most of the properties are also used in ADO. All properties and descriptions is from msdn.
Name Default Description Application Name The name of the application, or '.Net SqlClient Data Provider' if no application name is provided. AttachDBFilename
-or-
extended properties
-or-
Initial File Name The 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 Timeout 15 The length of time (in seconds) to wait for a connection to the server before tenating the attempt and generating an error. Connection Lifetime 0 When 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 Language The SQL Server Language record name. Data Source
-or-
Server
-or-
Address
-or-
Addr
-or-
Network Address The 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-
Database The 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 Size 100 The maximum number of connections allowed in the pool. Min Pool Size 0 The 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 Size 8192 Size in bytes of the network packets used to communicate with an instance of SQL Server. Password
-or-
Pwd The 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 ID The SQL Server login account. Workstation ID the local computer name The 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 connectionstring will be used.
If you are building your connectionstring in your app using values from user input fields, make sure the user can't change the connectionstring by inserting an additional property with another value within the user value.
