A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

when i upload my site on webserver and connect with remote sqlserver2005 using connection string.... 

<connectionStrings>
    <remove name="ConnectionString"/>
    <add name="ConnectionString" connectionString="Data Source=69.16.253.19,1433;Initial Catalog=vb_usa;Persist Security Info=True;User ID=username;Password=password" providerName="System.Data.SqlClient"/>
  </connectionStrings>

See the guide in this site http://www.connectionstrings.com/sql-server-2005

In particular look at the section on that page titled "Attach a database file, located in the data directory, on connect to a local SQL Server Express instance"

The format is:

Server=.\SQLExpress;AttachDbFilename=|DataDirectory|mydbfile.mdf; Database=dbname;Trusted_Connection=Yes;

Basically, you need to connect to the SQL Express instance installed on the web server and point it to where your database file is located.

Tried all the above but did not work for me. When I checked Services, I found that the SQLExpress service which was set Automatic, was not started. Once I started the SQLExpress service, everything worked.

On that remote machine (63.15.223.19), the SQL services are not running. You can go to that machine and try to run "net start mssqlserver" from command prompt.
