How to connect to the Remote Database using Connection String in C#.net
I want to connect a remote database using Sql Connection String in C#.net, I am trying it to do, but failed to connect.

C#

SqlConnection connect = new SqlConnection("server=SERVER\\MSSQLSERVER2008; Database = DataConverter; Trusted_Connection = True");

getting the following error

"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) "

ienabled TCP/IP in the sqlserver. Does it mean that remote system and local system not in network?

Check

1. Whether th SQL server can accept remote connection ?
In your SQL server management studio right click on the database and select "properties" and the click on "connection" in the left hand side and make you the check box "Allow remote conenctions to this servers" is ticked

2. Whether you can ping ?

ping SERVER

in the command prompt
3. Whether your instance name is correct ?
4. Whether the ports are opened on the firewalls to connect the SQL server
