Connecting to SQL Server 2005 - Not Allow Remote Connections

I use ASP.NET 2.0 and VS.NET 2005.

I have the following expression in my code:

string connectionString = "server=\'localhost\'; user id=\'sa\'; password=\'\'; Database=\'Northwind\'";

When I executed the code I have the following error message:

"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)."

The Microsoft Access was successfully connected in the Server Explorer window.

How do I solve this problem?

Thanks,

Andy.

From your link, I found the following link http://support.microsoft.com/default.aspx?scid=kb%3bEN-US%3b914277. I have followed all the instructions from that page, but I still receive the same error message.

I am not sure which version of SQL I am using. From the "start" -> "All Programs", I can only see "Microsoft SQL Server". It was installed, when I installed Microsoft Visual Studio 2005 Professional.

Andy.

Connecting to SQL Express from C# via connection string

I created a SQL Express database from within Vistual Studio. It had a
property ConnectionString, so I grabbed that value and attempted to use it i
n
code. (I did add an @. at the beginning and doubled the literal double quote
symbols.) The code that assigns the connection string and opens the
connection then looked like the following:
SqlConnection cn = new SQLConnection();
cn.COnnectionString = @."Data Source=
.\SQLEXPRESS;AttachDBFilename=""C:\MySolution\MyData.mdf"";Integrated
Security=True;User Instance=True";
cn.Open();
SqlCommand myCommand = new SqlCommand("Use FTTestLocal Create Table Asset
(AssetID int Identity Not Null Primary Key, AssetName varchar(150) Not Null,
Modified TimeStamp)", cn);
int ct = myCommand.ExecuteNonQuery();
When I run the application I get an error when the command is executed
stating "Could not locate entry in sysdatabases for database 'FTTestLocal'.
No entry found with that name. Make sure the name is entered correctly."
Thanks in advance for any help.Your connection string is attaching one database named
C:\MySolution\MyData.mdf and then you are trying to create a table in a
database named FTTestLocal. Either your connection string is wrong or you
are trying to use the wrong database. Perhaps you should explain what
you're trying to do so we can tell which database is appropriate.

>|||Thanks for your quick review of my problem. I apologize that I made a
type-o, and your solution addresses the type-o. In trying to simplify my
example, I removed a lot of cryptic pathing information, but accidently left
in the "FTTestLocal". The actual code is
ConnectString=@."Data Source=.\SQLEXPRESS;AttachDbFilename=""C:\VS
Projects\Personal Utilities\TableClassBuilder\FTTestLocal.mdf"";Integrated
Security=True;User Instance=True";
The SQL command is "Use FTTestLocal Create Table Asset (AssetID int Identity
Not Null Primary Key, AssetName varchar(150) Not Null, Modified TimeStamp)"
I've also tried
"Use FTTestLocal.mdf Create Table Asset (AssetID int Identity Not Null
Primary Key, AssetName varchar(150) Not Null, Modified TimeStamp)".
Interestingly, the error message did not change at all. It did not seem to
pick up the .mdf in any way.
As for what I'm trying to accomplish, I'm attempting to modify existing
code. Currently the code attaches to an online server running MS SQL 2005
using the previously referenced code. I need to modify it to work as close
as possible to the same way but to instead attach to SQL Express. This way
I
can continue to develop without always needing to go online.|||Try running
SELECT name FROM sys.databases
to get the name of the database. It is probably:
C:\VSProjects\Personal Utilities\TableClassBuilder\FTTestLocal.mdf

Connecting SQL2005 from older C++ client - the solution was ...

After setting up
SQL2005express server with
mixed authentification I got the problem

1. I couldnt find a working ConnectionString
2. Studio2005 didnt connect to SQL any more

In the meantime I found that at least the following OLEDB-ConnectionString is working, when Im logged in as admin and can use Windows Autentication:

Provider='sqloledb'
Data Source='.' - without '/SQLEXPRESS' !!
Initial Catalog='MyDatabaseName'
Integrated Security='SSPI'

For details of SQL setup and code to test possible connetion strings
please see my homepage.

text of my question from 02 Dec 2005
I want to feed data of a C++ 6.0 project into SQL server and hoped that StudioExpress would give me the correct connection string in detail.
But my StudioExpress doesnt conntect to a SQL server configured for SQL-Authentication.
I made screenshote of the details an put them in subfolders of my homepage
http://home.arcor.SQL2005.
Does anybody know what exact connection string has to be used and which changes in StudioExpress AdvancedConnectionProperties are necessary to establish a working connection?

The above link contains a collection of screenshots with details of the problem.
In the meantime I did a standard setup of the whole StudioExpress2005 C# paket and put screenshots on my homepage where you can see the difference between standard setup and single SQLExpress setup in SQL-Authentication mode.

connecting aspx to SQL Server 2000

Hello All,

I am just getting started on aspx, coming from an asp background.

I created the following connectionString in my web.config file:

<connectionStrings>

<addname="OuWebDB"

connectionString="server=OurServer;database=OurDatabase;uid=TheUser;pwd=ThePassword"

providerName="System.Data.SqlClient"

/>

</connectionStrings>

when I run this aspx file, from a machine, I get the following error:

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)

Help!!

thanks

Check outwww.connectionstrings.com for a proper connection string. Please search for these forums with your error message. I remember seeing previous posts with same question.

Sorry,

I did some searching around, and I still have the following issue:

I can not telnet to port 1433 (even localhost on the SQL Server 2000 machine).

1. TCP/IP and Named Pipes are both 'enabled' within SQL Server Client Network Utility.

2. I read something about having to be at a certain SERVICE PACK to overcome this error, is that the case? If so, is it for SQL Server or Win2003?

Other Question: Should I just stick to ODBC connection strings, which have worked well in the past, for my asp applications?

thanks..

I have found my problem, thanks... it is related to my service pack version

Thanks

You should change your database connection code like this,and it works well

SqlConnection myConnection =new SqlConnection("Data Source=localhost;Integrated Security=SSPI;Initial Catalog=Sample;");

myConnection.Open();

What's the error message? If it is something like 'Login failed for user xxx/ASPNET...', you can take a look at this post:
