I installed SQL Server 2008 on my machine which is (Windows XP SP3).
Also I have Visual Studio 2008 installed in another machine on which there is a .net application. Now while I am trying to connect to the SQL Server from my .NET application.
I am unable to do so. I get an error message :
The client was unable to establish a
connection because of an error during
connection initialization process
before login. Possible causes include
the following: the client tried to
connect to an unsupported version of
SQL Server; the server was too busy to
accept new connections; or there was a
resource limitation (insufficient
memory or maximum allowed connections)
on the server. (provider: Named Pipes
Provider, error: 0 - No process is on
the other end of the pipe.)
Is it because of the client version being 2005 (which gets installed by default with Visual Studio 2008) and SQL Server being 2008?
provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.
Do you actually have named pipes enabled for your SQL Server?

i have a windows server 2008 set up as a database server, i used to have MS SQL 2005 installed on it, due to some client changes i installed SQL 2008 R2 along with the 2005, the R2 is with a named instance. when i tried to connect an application to the 2008 R2 database, i get:
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: TCP
Provider, error: 0 - A connection attempt failed because the connected
party did not properly respond after a period of time, or established
connection failed because connected host has failed to respond.)
i am sure of the ports as i checked the named instance configuration on the DB server, i also telnet the dynamic IP from the application server and it is going through. i also tried to connect a copy of the application from a demo server i have with the same configuration as the application server and it was successful. from the application server it is not, any suggestions?

Viewing your linked images, is clear that you haven't installed or installed unsuccesfully,
Sql Server Express 2012
In your Configuration Server Manager there is no instancse of SQL Server so it is normal not been able to connect.
Q: Sine there is no instance,when you Launch Management Studio what instance name do you select when you try to connect???
You should properly install SQL Server Express 2012
EDIT :
First Check if you have any version of SQL Server or SQL Server Express installed on your machine...(this can be done by looking through installed programs from control panel)
In order to Install and configure SQL Express 2008 follow this steps
Take in mind that you have to use SQL Management Studio 2008 later on (if you have 2008 server)
Hope it helps...
I have deployed one vb.net desktop application and sql server is used for backend. It is properly working on local machine but when accessing database from remote machine it giving the error in the title.
I have done these things already:
Started SQL server, sql browser service using sql server configuration manager.
added the sql server, browser exe in to firewall allowed program list.
restarted sql server and browser.
enabled TCP/IP, Shared memory, Named pipes in SQL server configuration manager
enabled the remote connection for this DB in database property
I just installed SQL Server 2005 SP2 on Vista and am attempting to connect to my object explorer in Management Studio. When doing so I get the following error:
Cannot connect to localhost.
A network-related or instance-specific
error occurred while establishing a
connection to SQL Server. The server
was not found or was not accessible.

correct and that SQL Server is

I am using the following credentials:
Server type: Database Engine; Server name: localhost; Authentication: Windows Authentication
I am just using SQL Server for a local application. I have tried using 127.0.0.1, my comp name, "." and localhost. I have searched and tried every relevant help topic I could find. I have reinstalled, turned on IIS (just a guess), updated to latest service packs all around, run as admin, etc.
What am I missing here?

Did you run the User Provisioning Tool for Vista? See KB929907 You may be unable to perform most database operations after you log on to an instance of SQL Server 2005 Express Edition Service Pack 1 on a Windows Vista-based computer
Try using (local)
Also if you have an instance name you can try myComputerName\instanceName
You're missing the instance name. You don't just connect to localhost, but to any of the following (assuming that your machine is called dago and your instance sqlexpress):
localhost\sqlexpress
dago\sqlexpress
.\sqlexpress
I am not using express. It turns out I had a "client" version of SQL Server installed. I didn't even know there was a client version. I ran the full install and added the sa user as Windows Authentication wasn't working for me (next goal). I am connecting via "localhost" (just localhost), so I don't fully understand what the instance suggestion was all about.
Basically the solution was to get the full version installed. My bad. Easy fix.

I'm unable to connect to SQL Server 2005 from .NET. I'm getting the 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) ". The strange thing is, I'm able to connect through management studio using the same credentials (SQL Server authentication).
My connection string is: Server=servername;User ID=xxx;Password=xxx
I'm using the 2005 native client.
Also, I just realized Management Studio cannot connect if using named pipes, only TCP/IP.
What tells ADO.NET which protocol to use?
SQL Server 2005 may not be allowing inbound named pipes connections. This can be configured differently for the older SQL Server protocol and for the 2005+ Native Client. Check the SQL Server Configuration Manager on your database server.
(And yes, the Management Studio would still be able to connect to the remote database if named pipes were disallowed.)
