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.]
Please help!
Thanks!
Your SQL Server doesn't allow for remote connections. Depending if you have access or not,
follow this url http://support.microsoft.com/kb/914277
But, this is pretty insecure, good luck.

I cannot connect to any remote SQL Server instances from my system. I used to connect them from SQL Server Management Studio. Moreover, I can still connect to the same SQL Servers remotely from another systems (my colleagues' system).
I am getting 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (.Net SqlClient Data Provider)
Error Number: 53
Severity: 20
State: 0
I have checked:
Named pipes/TCP is enabled.
Remote connections are allowed.
Windows Firewall is off.
Enabled everything in SQL Server Configuration Manager.
Also, I have tried everything mentioned in this post-
How do I fix the error 'Named Pipes Provider, error 40 - Could not open a connection to' SQL Server'?
But still could not solve my problem. Please suggest any method which allows me to fix this error and connect to the remote servers again.
instead of check whether that server system is working or not, because sometimes if the server system is not working means we are unable to connect to that system
While connecting to SQL Server 2005, I am getting 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) (Microsoft SQL Server, Error: 2)"
I restarted the Server and then tried to connect to SQL Server, it is allowing me to connect. Whenever the problem comes, I am restarting the server. But I want the actual solution for this problem.
Can anybody help me out in solving this issue.

I think probably you haven't configure any Azure DB firewall rules to allow your computer's IP to communicate with your Azure DBs.
Simple things to check (not sure what you've tried so humour me here):
You're connected to the outside network.
Instance\Database name, username and password are correct.
Instance and database are online and connectable (Azure servers not down for scheduled maintenance or run out of paid services.)
Firewall rules are incorrect.
Also I think this question here is identical to your question. Try checking that out.
I tried to login to a remote server and I saw the error given at the link -

Explanation
SQL Server did not respond to the client request because the server is probably not started.
Arent the message and explanation contradicting each other ? Which one is the correct reason for the problem ? How do i find out the REAL source of the problem ?
They don't contradict each other. They just give different possible reasons:
SQL Server doesn't allow remote connections
SQL Server is not started
To fix it, make sure that SQL Server allows remote connections and is started.
Allowing remote connections can be done in the "SQL Server Configuration Manager":
Start that program on the server on which SQL server is installed.
Navigate to "SQL Server Network Configuration" -> "Protocols for "
Double click on the connection type - e.g. Named Pipes - and set "Enabled" to "Yes".
If you are enabling TCP/IP, make sure to also enable each individual IP address on the second tab.
See this blog post for more info.
Thee program you are using is unable to find SQL server on the port/address it expects to.
This is likely either because it is misconfigured, or because SQL server is stopped.
I suggest you open a desktop login to the machine in question, and see if SQL server is running.
There are other potential causes for this problem, as well: network problems, for example.
An error occured while establishing a connection to the

server 2005, the failure may be caused
by the fact that under the default

remote connections. (provider: Named

I am using .NET framework provider for SQL Server and Visual Studio 2008.
Data Source=.\SQLEXPRESS;AttachDbFilename="";Integrated Security=True;User Instance=True
What am I missing here?
I know external references are bad, but it really does not get better than this:
http://www.connectionstrings.com/
as they say
Server=.\SQLExpress;AttachDbFilename=c:\mydbfile.mdf;Database=dbname; Trusted_Connection=Yes;
AttachDbFilename should be the path to the database filed (generally a .mdf) that you will be using.
Data Source=.\SQLEXPRESS;AttachDbFilename=c:\some.mdf;Integrated Security=True;User Instance=True

By default SQL Server Express disables remote connections via TCP/IP and Named Pipes, so you will need to enable these protocols in the SQL Server Configuration Manager (Start --> Programs --> Microsoft SQL Server 2008 --> Configuration Tools).
I also agree with Hogan about ConnectionStrings.com great site!
