I have been unable to configure my SQL Server 2008 Express to allow remote connections. I followed the instructions from this guide: http://www.linglom.com/2009/03/28/enable-remote-connection-on-sql-server-2008-express/ .
I am still getting the following error:
Cannot connect to 00.00.00.000
Additional information:
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: Named Pipes Provider, error 40 - Could not open a connection to SQL Server) ( Microsoft SQL Server, Error: 3)
I also configured the firewall as defined in http://blog.sqlauthority.com/2009/05/21/sql-server-fix-error-provider-named-pipes-provider-error-40-could-not-open-a-connection-to-sql-server-microsoft-sql-server-error/ . As a test I even turned off the firewall, but nothing changed, so it is not the issue.
Update under server name, it only says the IP address. Do I need something more?
In the Server name field of Connect to Server, I had myipaddress. I changed it to myipaddress\SQLEXPRESS and it works.
In addition, once this was working without the firewall I applied settings as defined in http://www.sevenforums.com/system-security/58817-remote-access-sql-server-express-2008-windows-7-a.html to make the connection work with the firewall turned on.
Do you have sysadmin rights in sql express? It may be that your user account doesn't have the necessary permissions. There is a script on codeplex that will add you logged on account as a sysadmin.

Error message is like this:
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: 51 - An instance name was not specified while connecting to a Local Database Runtime. Specify an instance name in the format (localdb)\instance_name.)
And my scenario: IIS and SQL Server 2008 are on the same test workstation, whose firewall is not enabled at all. I don't see any SQL Server log so I can't find any other useful information than the error message above.
I installed SQL Server as default instance (MSSQLSERVER)
My connection string is like this (I am using SQL Server account for authentication):
Server=(localdb); Database=MY_DB_NAME; User ID=MY_USER_ID; Password=MY_PASSWORD
I already verified this user has access to the target database (as owner)
I have gone through some articles on how to track down this problem: I set "allow remote connection" even though IIS and SQL Server are on the same machine. I don't need to set-up firewall.
If you have a standard, unnamed instance, you should use . or (local) (but not (localdb) !) as your server name
Try to use this connection string:
Server=(local); Database=MY_DB_NAME; User ID=MY_USER_ID; Password=MY_PASSWORD
I am trying to connect to a sql server in my asp.net application. I have given connection string in my web.config as follows :
I am getting following error while running the application :
"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)"
If i use remote server's ip address as data source in connection string, I get following error
"Login falied for user 'sa'"
I researched and found some ports need to be opened between the server and my machine, which I got done by network team, still the same issue. How to resolve this ?
You can not directly. you need to have TCP/IP enabled and configured the TCP/IP Ports on sql server configuration manager at remote server.
you need to have TCP/IP connectivity .Just launch it, enter the DNS host name or IP address in the Server Name' box and hit Connect. The hosting company needs to have enabling TCP/IP on your SQL Server instance, and them providing you with secure access to the IP address that instance is running on.
Most administrators do not allow direct access to the SQL Server from outside the firewall. In that case, if you can connect to the host over VPN then you should be able to connect directly to the server with Enterprise Manager or SQL Management Studio.
Please go through it Configurations-Remote-Server
Are you porting code from Hypersonic or H2? If so, the username sa won't work.
I have been trying all kinds of tricks - from enabling TCP/IP, adding exception to firewalls to poking bill gates vodoo doll. But nothing seems to work for me. Is it really that difficult to connect to sql server 2008 via management studio ? Maybe, robbing a bank would be easier.
While i figure out which bank to rob, can you help me to fix the problem ?
When I try to login to sql server 2008, this is the error i get-
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

The links i tried so far -
blog.sqlauthority.com/2009/05/21/sql-server-fix-error-provider-named-pipes-provider-error-40-could-not-open-a-connection-to-sql-server-microsoft-sql-server-error/
and some more random links on the net.
When you installed SQLServer, there are several options that may affect the way SQLServer runs and how you have to connect to it. The link you included in your question that points to the sqlauthority blog has an additional thread posted by Vince. Be sure to follow those instructions so that SQLServer will be set to listen on port 1433 and not a dynamic port.
Also, when you log-in, if it tells you that the login fails (e.g., for xxx\yyy), then you probably missed the option in the install to add the current user as an authorized users. In that case, you will have to log in through SSMS using SQL Server Authentication, and provide sa as the username and the password that you set during the install.
After you log in, you can add your Windows user account to the list of authorized users by expanding the root Security folder in the SSMS object explorer, right-click Logins and select New Login. From there you can search for your user account and add a Windows authentication user. That will make it possible for you to log in using Windows Authentication so you won't have to type your password every time you launch SSMS.
I have an application which connects to SQL Server 2008 via windows service.Basically,windows service pics up a configuration file to get connection details like instance name , user name & password.Currently this windows service is failing to start with following error message :-
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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Application server and DB server are different machines.I can connect to SQL Server via SSMS from application server without any issue. Also I created a UDL on app server and it also connected fine to DB server. Any help here is much appreciated.
Check the account under witch windows service is running- most possible that account is not allowed to make connections to other computers.
I get the error message below when accessing Reporting Services through a browser

Have you verified that the configuration is correct? Use "Reporting Service Configuration Manager" which is installed with SSRS. Step through the screens looking for problems; try applying the configuration and make sure databases exist and have correct permissions.
Try running RSConfigTool.exe or Report Services Configuration Manager from Windows and check if the server is accessible
