Hi all...

I am developing a multi-user program using VB.NET and SQL SERVER 2005 (VS 2008).

I've done almost but when I am trying to connect application to SQL SERVER, it gives an error message that "An error has occured while establishing a connection to the server. When connecting to SQL Server 2005,this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.(provider:SQL Network Interface, error : 26 - Error Locating Server/Instance Specified).

I used the following connection string :

VB

Dim conStr as String = "Data Source=192.168.1.200\SQLEXPRESS;Initial Catalog=demoDB;Integrated Security=True"

Suggest me what should I do.

Thanks.

The error is pretty specific: check the SQL server instalation and make sure it is configured for remote connections.

Also check your SQL server instance name, and that the IP is correct - it's a LAN based IP, so it may well be dynamically assigned by your router depending on the order in which devices are powered up. Make sure you can make a connection using Visual Studio, in the Sever Explorer pane, and look at the ConnectionString property for the database in the properties pane.
