I have a simple asp .net web project I'm working on, and while normally everything is going fine, if I try to debug the site, I get "SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified". I'm not sure if its a weird code issue or a weird SQL Server Issue, but here are the system specs anyway.
My dev machine is Windows 7 32-bit, and a Windows Server 2008 VM (on the same Windows 7 Machine) runs both IIS and SQL Server 2008 Express.
I haven't had any other problems with the connection string I'm using, and I'm using the simple SA account.
Following is the error I am getting while accessing some of the pages on my website.

It is trowing an exception and giving the about mentioned error.

View 4 RepliesI 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:

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 trying to deploy my .NET webservice on to provider (somee.com). I published the webservice and copied the folder over to the hosting site. I have my App_data folder copied too. I can access the service webpage. But when trying to access the website I received the following error. I have sqlserver express on my local machine.

I just ran a project that I've been working on and the project couldn't connect to the sql server engine. This project worked fine yesterday. This morning I installed the new Adobe Flash player 10.0. That's the only thing that's changed sine I last worked with my project.
I got an exception for the sql server error when I run my app. This is the exception from the app:

I tried to connect to the engine with the ssms but couldn't connect that way either. This gave me an error that said:TITLE: Connect to Server
I'm running SQL Express 2005 on an SBS 2003 Standard Server and I keep getting this error back.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: 28 - Server doesn't support requested protocol)
I've uploaded my project to this same server, and I've so far checked that TCP/IP has been enabled for this instance, I've checked the IPs are relevant, I've checked that the connection string is correct, and I've even set a dynamic port number as I've noticed that SBS runs 2005 databases for Sharepoint and Monitoring.
Interestingly enough, I can connect to this instance via Visual Studio on my remote machine, and SSMSE and also via SSMSE on the server as well?The connection string i'm running with is:
Data Source=localhostVDSSQL;Initial Catalog=myDB;Persist Security Info=True;User ID=SA;Password=***
I am working on sql server 2000.I have only one instance running on SQL SERVER 2000.I have the instance name as 'ashvinDIT0934/sys07DIT' registered somehow.But i need to have it simply as 'mycompanyname' (no changes but as 'mycompanyname'). how i could change it and have the instance name changed.The instance name that i have given above i.e (ashvinDIT0934/sys07DIT) when inserted into the connectionstring does not work.It says as invalid escape sequence.So hence i need to have it as 'mycompanyname'
View 3 RepliesI'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:

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

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 not sure what am I doing wrong, but I followed this article below step by step and still I am getting the same error

My instance name is MSSQLSERVER and the server that I am using is on my local machine and it has my computer name in it.
I just installed sql server 2005 to my pc and when i try to log in to the server instance i get an error log in failed for user xxx (error 18456).I browse to the server instance and i keep getting the same error even though i chose windows authentication option during the installation.
I restarted the service for the sql server instance (which is running).The only problem i can think about is a problem with permissions but again there should not be any problem there because i logged in as administrator
I have never created my own solution before now. I have always modified existing solutions and know how to do it. For some reason, this new solution isn't connecting to my SQL server correctly.
I am using VWD 2008 Express Edition.
I have MSSQL 2008 Developer Edition.
I have used aspnet_regsql.exe to create the tables in my SQL DB.
I have added the following to my webconfig:

But for some reason, when I try to use the Web Site Administration Tool it thinks it is not setup.
What am I missing?
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

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:

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'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 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?
