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 recently did an OS reinstall and tried to use my previously-working projects. I found that there was trouble connecting to the database for my aspnetdb.mdf. I have also tried a new project and adding a database to the project but I get the error 'a network related or instance specific...' error. I have tried reinstalling sql server 2005 express but still no luck. When I fire up sql server management studio i see the server name is the same as my computer name. I remember before the os reinstall that the server name was 'sqlexpress'.Anybody got any ideas as to how I can create databases inside of visual web developer again?

I've created a small website with a simple sqlite database using vwd 2010 .net 4. In dev and test envionments everything works fine, however when i promote to my hosting provider i receive the 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
I've been configuring the connection strings (autogenerated from entity framework and attached db) but unable to get it working on the hosting provider, I'm assuming it's related to permissions but not entirely sure how to resolve - here's the web.config as it stands:
<add
name="ApplicationServices"
connectionString="data [code].....
For info the environments are set up as follows:
- Dev environment is vwd express 2010 with sqlite mdf attached
- Test environment is windows 7 server, iis 7 with appdomain identity set to network service

I am using Asp.Net MVC 2.0 for creating a user and assigning properties to the user at the same time. I am using my Windows account to access database on my local computer. I am using pre-installed MVC code o create a user with unique user name and password. User is created OK. Then I want to add profile properties like First and Last name at the same time.
I am creatingProfileBase object:
ProfileBase profileBase = ProfileBase.Create(profileInformation.UserName);
where profileInformation is a RegisterModel and has user info.
When I am trying to:
profileBase.SetPropertyValue(.....);
I am getting the following error # 2147467259 A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

Why is my connection string works fine the first time and not working now? And how to configure connection to use TCP-IP?
I have SQL Server Browser running ander Local account and openned port in my Firewall.

I am REALLY stuck with this and need a solution in the next 24 hours .i I have uploaded my asp.net web application to the web and have the database and connection strings functioning and reading the data from the database. But when I try to write to the DB
I get the following error :
Server Error in '/' 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)
Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: 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)
The wierd thing about this is the connection strings work from the local machine when I run from Visual Studio and I can write to the DB there, I just cannot write to the DB from the URL.
I am pretty new to asp.net but I am sure it has to be something to do with the web.config.

I am trying to create a simple login page in ASP.NET C# but am getting some error.
I googled about the error, and tried all the solutions but to no avail.What am I doing wrong? The error is:
"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)"
I think it's something to do with my connection string which is as follows:
<add name="cn"
connectionString="server=HCL;DataBase=GS;Integrated Security=True" />
"HCL" is another machine connected to my PC through the LAN and this database, "GS", resides on it. Is the problem with the value I am giving in "Server" attribute of the above code? If not what else may I be doing wrong?

I have a VB.NET ASP.NET webserver program running. One or more VB.NET clients are making use of it. Nothing special so far. As far as I know, the server is not really aware of the clients. Clients can request data. But is it also possible to let the server call-back a specific client when something happens? So that the client doesn't need to poll?
To be more specific, this server is connected with hardware modules. Clients could be terminals that show the status of a sensor for example. When a sensor gives an "alarm" value, it would be nice if the server could pass that alarm towards the clients. Instead of letting the clients to check each X seconds if that alarm is active. Would be a waste of energy, especially because the chance this alarm goes off is almost zero...

I have a server application that runs in a hosted environment but creates print jobs in the client's local network (behind NAT; the mechanics of this is not relevant).
In order to send the print job to the printer that is attached to the workstation, I need to identify the workstation. The users move around between workstations, so I can't permanently associate a user with a workstation/printer. The trivial solution is to require the user to identify the machine he is logging in from, for instance by selecting from a list, but that's an inconvenience and subject to user error.
Options I have eliminated:
Host header variables (nothing identifiable is sent) Cookies, in support of a user selection. This somewhat addresses the potential for user error, but not really. HTML5 DOM Storage - is not supported by the client's browser
Edit: I do have the option of puttnig this particular function (create a print job) into a thick client app. The app can then of course be configured and the problem goes away. But the user experience will suffer from having to switch between the browser and a Windows app.

When I load the asp.net config tool in vs2010 it loads the page up fine but as soon as I click on security I get the following error:-
Code:
There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store.
The following message may diagnose the problem: 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. I have tried a blank project with a login control on but get the same.

I have an asp.net (FW 3.5) web app that runs on an internal network. One specific page needs to "report" in to the web server that it is active and not locked up. I need to be able to run a script (or something) at the client to report the pc's computer name in that report. I cannot find a method that does this. I found several things that would report the WAN IP or host name, but this appears to all be for external facing sites.

I have a stored procedure which is composed of three unions of three different views.
After the views are Unioned together, they are placed into a temporary table.
I need to somehow keep track of the data which comes from the second view, "View2".
Specifically I will later need to compare all Ages of people from the second view.
How can I do this? Here is an example of my unioned views
Select Name,Age,Gender from View1
UNION
Select Name,Age,Gender from View2
UNION
Select Name,Age,Gender from View3

As working with ip address in Sql Server needs some Efforts than mysql b'cos it Doesn't has INET_ATON() functionality. even though we create a Function to do that. But as per Requirement if ip address and postid should be Unique with One Post Question. than its some more complex to implement. so i need a solution without compromising my Disk space, 4 Tiny int field for ip address can be used but comparison will be more Hard to achieve. b'cos it is a composite primary key.

My ASP.NET MVC 2 application runs under built-in local NETWORK SERVICE account. I want to set up access permissions for the folder which resides in another computer, but in the same domain. I located that folder right-clicked to open its properties form, clicked to Security tab and pressed Add button which displayed Add user form with correct domain name in the location field. I referred to the account with following syntax:
<domain name><server name>$
because I learned that NETWORK SERVICE account uses machine account when connected to other computers in the domain. However, the system couldn't find the account, so refuses to add the account. Without the domain name it adds a user, but that user seems to be local user, not web server's NETWORK SERVICE account. What am I doing wrong?
By the way, the above syntax worked when I created login for the sql server which is different computer from the web server.
