I am using Sql Server 2008 to connect to a Remote Server. Everything was working fine for the last couple of months, and i was successfully connecting to the remote server. Today it suddenly stopped connecting to the remote server. note that i did not alter any configuration settings. Did my isp block Sql Server. My ISP is using ISA SERVER? The error details are:
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) I am using Microsoft Firewall Client For ISA Server for opening ports. But today nothing is working.

I am unable to connect to my local instance of SQL Server 2008 Express using SQL Server Management Studio.I believe the problem is related to a change I made to the connection protocols. Before the error occurred, I had Shared Memory enabled and Named Pipes and TCP/IP disabled. I then enabled both Named Pipes and TCP/IP, and this is when I started experiencing the problem.
I have now set Named Pipes and TCP/IP back to disabled. When I try to connect to the server with SSMS (with either my SQL server sysadmin login or with windows authentication), I get the following error message:
"A connection was successfully established with the server, but then an error occurred during the login process. (provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233)"
My first question here is: why is it returning a Named Pipes error? Why isn't it using Shared Memory? It seems like it is not listening on Shared Memory for some reason?When I set Named Pipes to enabled and try to connect, I get the same error message.My windows account is does not have administrator priviliges on my computer.

I'm a bit of a beginner to ASP.NET and I'm having a trouble connecting to SQL Server Express.
I'm using Windows 7 and have tried connecting to my database using both Windows authentication and a user account I setup in SQL Server.
I've include the code I'm using below (using the account I setup in SQL Server):
[Code]....
The error I get is that it can't login using the login details provided
Just wondering if there's anything I'm not doing something properly? This is the first time I'm trying to connect to a database using Windows 7/SQL Server Express so hoping someone with a bit more experience can give me a hand!

I'm trying to publish an ASP.NET website over an IIS 6.0 (Windows 2003 Server), and I have some troubles trying to connect to the database. Curiously, I have installed another ASP.NET website into the same IIS 6.0 with the same properties and security parameters and can connect without problems with the same database. The application that works fine is almost the same that the one that can't connect with SQL Server (actually is the same but with several modifications).I'll enumarate some information related to the problem:
S.O: Windows 2003 Server
SQL Server Engine: SQL Server 2008 SQL Server accept remote connections? Yes.
ASP.NET version: 2.0.50727
The connections via TCP/IP are enabled to the SQL Server instance? Yes.
The corresponding user that I have in the connection string, actually exists into the database with the "owner" role? Yes.
ORM Tool used: nHibernate
I get the following error when I try to run the aplication into the browser:
Error while establishing a connection
to the server. When connecting to SQL
Server 2005, this failure may occur
because the default settings SQL
Server does not allow remote
connections. (provider: Shared Memory
Provider, error: 40 - Could not open a
connection to SQL Server)
I made some test. For example, using the web app that works fine I can connect without any problema with the database that uses the web app that can't. With this evidence I concluded that the problem is within the web app and not into the SQL Server instance.

I started a new Sql Server 2008 with mixed authentication Windows and SQL SERVER AUTh... I created a new login account and use it to directly connect in SQL server managment studio BUT... when i create in VS2008 the connectionstring... everytime i try to open the DB connection i take an exception to the login... some screenshots show all the process ;)
LOGIN: admintvmaismais
PASSWORD: ex
Working to connect in SQL SERVER MANAGEMENT...
LOGIN STATUS ON SQL SERVER MANAGEMENTE
Now in VS2008 Web-Config I declare the connectionstring:
<connectionStrings>
<add name="SqlConnectionString" connectionString="Server=JP;Database=tvmaismais;User ID=admintvmaismais;Password=ex;" providerName="System.Data.SqlClient" />
</connectionStrings>
and When i try to open a connection like this:
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["SqlConnectionString"].ConnectionString);
try
{
conn.Open();
...
}
catch (Exception e)
{
retorno = e.Message.ToString();
}
finally
{
if (conn.State == ConnectionState.Open)
conn.Close();
conn.Dispose();
}
I get this exception: Cannot open database "tvmaismais" requested by the login. The login failed. Login failed for user 'admintvmaismais'. What am I missing? What do i need to do, to get this login to work?

I just started getting the error message "Unable to Connect to the ASP.net Development Server" when debugging a website with VWD 2008 (everything was fine in the past). My system is Windows Vista with Windows Live OneCare firewall. I have reviewed other postings related to this problem, and they indicate firewall setting problems - settings not allowing VWD internet access. However, my settings on the "Windows Live OneCare Firewall Advanced Settings" tab specifically allow VWD.

I have my code here, it works fine from my home, where my user is administrator, and I am connected to internet via a cable network.
But, problem is when I try this code from my work place, it does not work. Shows error:
"unable to connect to the remote server"
From a different machine in the same network:
"A socket operation was attempted to an unreachable network 209.xxx.xx.52:25"
I checked with our network admin, and he assured me that all the mail ports are open [25,110, and other ports for gmail].
Then, I logged in with administrative privilege, there was a little improvement, it did not show any error, but the actual email was never received.
note that, the code was tested from development environment, visual studio 2005 and 2008.
try
{
MailMessage mail_message = new MailMessage("xxxxx@y7mail.com", txtToEmail.Text, txtSubject.Text, txtBody.Text);
SmtpClient mail_client = new SmtpClient("SMTP.y7mail.com");
NetworkCredential Authentic = new NetworkCredential("xxxxx@y7mail.com", "xxxxx");
mail_client.UseDefaultCredentials = true;......

I'm getting "Cannot connect to ASP.NET development server" almost every time I stop the ASP.NET server before restarting the project in debug mode. It can take between 15 seconds and 2 minutes to get the error message, and Visual Studio is frozen.
Sometimes I get three in a row, and I have to wait 2 minutes each time, or go into Task Manager and kill to process. Then I have to start Visual Studio 2010 again, which is at least three times slower than Visual Studio 2008 to open.
It's *extremely* annoying. I know I don't have to close the server if the code has changed, but sometimes I simply want to restart my website in debug mode (there is a cache on most web service calls, so this clears the cache). A workaround is to add "foo" code to a class and restart the project.
I'm running Visual Studio 2010 Professional on Windows Server 2008. I'm running the Visual Studio Power Tools too, with the latest update.

I have created web pages using VS Web Developer that use a local Developer Edition of SQL server database on my PC with LINQ to SQL. When I deploy my website to a remote web host SQL server, I need for my web pages to be able to use the remote database instead of the local database. So, how do I get the Server Explorer to connect with a remote SQL Server database?

I am developing and app to find automatically characters stats with the 2nd edition dnd rules to be easy for my party to create characters when we play.
I am using Visual studio 2010 c sharp express and Sql 2008 express R2.I have added a database in the project to have all the data needed. When I use the release folder or the debug folder on other pcs the app doesn't run. Wherever I install SQL server (database and management) things are fine. I googled but I am not sure what to look exactly for and made a brief search here but with no results. I am trying to make sth that has almost no dependencies but well I can't avoid installing .net framework 4 everywhere...
Is there anyway to make database work without installing SQL? Is there any workaround like a dll or sth?
