Trouble connecting to SQl server 2005
-
Hi guys, I've got this problem, hope someone can help me out. I've written and application and it works fine on my computer and i can connect to SQL through a Text file connection string in the Text box : Data Source= NameOfMyDataSource;Initial Catalog= DataBaseName ;Integrated Security=True As I said, it works fine on my computer but NOT on other computers !!! I installed my application on another computer and also installed SQL server, then attached my database and it works fine, but when i run my progran and enter ID and Pass get this error ! System.Data.SqlClient.SqlException: An error has occurred 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) A friend from here suggested: By default, SQL Server blocks remote access. To get round this, log into SQL Server Configuration Manager and make sure that you have enabled Named Pipes. Then, go into the Surface Area Configuration Tool and make sure it's set for Local and/or remote connections for Named Pipes. Now, restart the SQL Server instance. I did that but still get the same error !!! what should I do ??? Thanx
Check these two things, it might help: 1. Add SQL Server instance to the permitted list of applications in the firewall settings (Control Panel-> Security) 2. Check if port 1434 is not block using telnet 1434. Regards, Pratyush Shukla

One more thing to check - make sure that you are using the database instance name, if any.
Deja View - the feeling that you've seen this post before.

I am guessing that your servername is incorrect. On the machine that it is not working on, try ping the server name. If you are using something like localhost that for sure would not work on remote systems. If you can't ping the sql server, then you might have a name resolution issue which would be solved with a DNS entry on your network. Hope that helps. Ben

Adding another issue, you may not be able to use Integrated Security (Windows Authentication) if the server and client are not members of the same domain. If they are not, the user running the client needs to have a Windows account on the server and the passwords need to be the same. Also, your database server will need to grant the CONNECT privilege to the user or to a group that the user belongs to, and the login will need to be mapped to a user in the database you're trying to use, with appropriate rights for what you're trying to do.
