The connection string builders allow you to construct syntactically valid connection strings at run time, so you do not have to manually concatenate connection string values in your code. Microsoft SqlClient Data Provider for SQL Server introduced the following connection string builder. For more information on connection string syntax, see ConnectionString. The specific connection string syntax for the SqlClient provider is documented in its ConnectionString property. has a Connection object that inherits from DbConnection as well as a provider-specific ConnectionString property.

(provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)ĭescription: An unhandled exception occurred during the execution of the current web request. Thanks in advance.Ī network-related or instance-specific error occurred while establishing a connection to SQL Server. I checked the logs and the event viewer and nothing seems obvious to the cause of the error. I have checked that the settings on the server i.e. Now DB1 web client is held on another server, it is through the web interface that i receive this error message. Yet all the other db's are able to be accessed. My problem here is a database (DB1) that resides on a 2005 server with 20 other databases. Hi all, i'm not sure if this is the right place to put this post, so if anyone has an alternative place for it to go then please, suggest away.
