无法连接到SQL Server DB

Question

I'm trying to connect to a DB and I followed the connection string suggestions . However, I'm not a DB-guy so some things are, hrmp... less than obvious.

For instance, the DB server is within the network and the connection to it goes from another server, also in the same network. I've used the server name and port to connect to it using Management Studio so it's up and running.

This is my connection string.

System.Data.SqlClient.SqlConnection conn = new System.Data.SqlClient.SqlConnection();
conn.ConnectionString =
  "integrated security=SSPI;"+
  "server=server.name.as.in.management.studio,4340" +
  "persist security info=False;database=NameOfTheDb";

The authentication is done using AD and the error message is 40 - can't find the server. Besides the obvious - the server can't be found - what can I do to trouble-shoot this, obtain more information etc.?

I'm at a customer and their system is not as well documented as one'd like. I get very little information and the coverage is questionable. The person who set up the attrocity is gone since a long time.

Suggestions are welcome.

EDIT

Following the corrections provided, I'm getting error code 0 - The requested name is valid but no data of the requested type was found .

What do I do with this?! :)

Answer 1

System.Data.SqlClient.SqlConnection conn = new System.Data.SqlClient.SqlConnection();
conn.ConnectionString =
"integrated security=SSPI;"+
"Data Source=myServerAddress;" +
"persist security info=False;" +
"Initial Catalog=NameOfTheDb";

Hope this helps.

Sure servce in Managmnet Sql Server is Start . You can do that by go to ---> Control Panel-->All Control Panel Items-->Administrative Tools--Services --> SQL Server(MSSQLSERVER) and click Start .

System.Data.SqlClient.SqlConnection conn = new System.Data.SqlClient.SqlDbConnection();
    conn.ConnectionString =
    "Data Source=ServerName;" +
    "Initial Catalog=DataBaseName;" +
    "User id=UserName;" +
    "Password=Secret;";
    conn.Open();
