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 ADO.NET SqlConnection object. Most of the properties are also used in ADO. All properties and descriptions is from msdn.
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.
