I'm new to Visual Studio and SQL Server. Basically, I have purchased Microsoft Visual Studio 2010 premium but am having some problems. I have a very basic application with a registration form (CreateUserWizard) and every time I try to run it I get error 26 server instance not found.
"provider: SQL Network Interfaces, error: 26 - Error Locating
Server/Instance Specified"
When I open SQL server configuration all of the server instances are stopped SQL Server (SQLEXPRESS), server agent and server browser. When I try to start them it says "the response failed or did not respond in a timely fashion" When I try to edit the filesystem or any of the server settings I get a message "The specified resource name cannot be found in the image file". I tried to refresh my laptop and delete all applications and server instances, but the error still persists. I just wanted to know is there anyway I could reset the SQL server to default setting (I think I may have mistakenly deleted MSSQLSERVER) and reinstall visual studio. It did work on my laptop before. Thanks in advance for all your help. Using visual studio 2010 with VB.net
Got it sorted. Installed SQLSERVER and enabled the server browser during setup.

I'm trying to setup a local version of a website that's online and working. The site is built with Umbraco V6, and is using an SQL Server database. My test server is a fresh install of Server Standard 2012 and SQL Server 2012.
My process has been to:
Install the O/S and SQL Server
Setup a test Umbraco site in IIS, installing from scratch into a fresh database
Once 2. is working, download the source code from the live server and install in a new site in IIS
Download a copy of the live SQL Server database and restore it into the server
Add a new user account into SQL Server, granting permissions onto the SQL database i've restored
When I try to access the website through a browser, I get an error. This shows up in IIS as:
Event Code 3005. An unhandled exception has occurred. No connection could be made because the target machine actively refused it
I've disabled the Windows Firewall and have checked I can telnet into the server on port 1433. I know the Web.config is using the right credentials, as I can change it to a different user account and see a different error.
Can anyone point me in the right direction to resolve the error?
You should go through the steps listed over here:
http://blogs.msdn.com/b/sql_protocols/archive/2007/07/19/tcp-provider-no-connection-could-be-made-because-the-target-machine-actively-refused-it.aspx
I suspect that your connection string is pointing to the wrong server instance or that the TCP protocol is not configured correctly.
Tip: You can always copy and paste the settings from your connectionstring into the Connect Object Explorer of SQL Management Studio to verify that they work.
I opened my web project today and for some reason I could not gain access to my database files. I get the following exception whenever I try to add, edit or refresh my database:
A network related instance specific error occurred while establishing
a connection to SQL Server. The Server was not found or is was not
accessible. Verify that the instance name is correct and that SQL
Server is configured to allow remote connections.
I took a look at my connection string for any spelling errors and deleted my database and replaced it in the folder I had it in. I can't seem to find a fix for this so any help would be a appreciated. I am using Visual studio 2008 for this web project.
This sounds like the same problem that I had myself awhile back. My problem was that my SQL service pack 1 did not install properly so I had to install Microsoft SQL Server System CLR Types, Microsoft SQL Server 2008 Management Objects and Microsoft SQL Server 2008 Native Client. After that I could create new SQLdatasources but I could not edit the ones I had previously before my problem. I had to restart my computer in safe mode and delete my SQLEXPRESS folder then recreate the database connection in visual studios. When I finished that everything worked fine.
This is the site I got those downloads, http://blogs.cametoofar.com/post/cannot-load-file-or-assembly-microsoftsqlservermanagementsdksfc.aspx
(The database is on my PC)
My database worked just fine for a month, and then this error came. It is not related to a specific file, nor a specific project (Even if I'll create a new website and try to add a new database file, this error will pop)
I guess it happens because the sql server is not running on my PC, and it is true that I don't see any sql related process running.
How the I fix it?
P.S. I know this error has a lot of threads on the internet and even here in SO. But most of them solve the problem for a complicated, secured connection with a remote server. All I want is to create a new empty ASP.NET website and add a new .mdf file for it on my PC.
It may be related with the SQL Service authentication which you have to verify from the control panel->Administrative tools->Services. Locate SQL Server(Express) Try changing the Log on As Network Service instead of local system.
that is a error Locating Server or Instance.
Try connecting by IP.
Have you disabled SQL Server browser?
I was facing something similar so I will share how I solved it, it might work for you or not, but here are my 2 cents.
My environment: Windows 10 ( upgraded from windows 8 in which SQL Server was working fine)
SQL Server 2014 Express
Solution: I Opened the services program, and found the SQL Server services, I saw that all of of them were up except by one which was disabled, the "SQL Server Agent", I enabled it and was able to connect to my DB instance.
Hope it helps

I just created my first ASP.NET Version 4 app using Visual Studio 2010 and SQL Express 2008.
I copied the files to IIS and run the default.asp. This loads the programs main menu. So far so good.
When I open the read webform and do a read of my database I get the following Error:
Server Error in '/Diary' Application.
Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed.
Any idea how to fix this error?
Did you look at support articile for the very issue.
Or even this
We have an ASP.NET application written in Visual Studio 2003 (c#) using SQL Server 2000 as database. It’s an old web application that our clients have been using for 4+ years.
Now, we needed to upgrade the application to work on Windows Server 2008 using SQL Server 2008, both 64bit, both on the same machine. So we ported the application to Visual Studio 2008, made some needed modifications and successfully installed the application on Windows Server 2008 with database still being the old SQL Server 2000. Everything worked fine. But as soon as I modified the connection string to work with the new SQL Server 2008 64bit, it stopped working. Basically the web browser just shows – The webpage cannot be displayed; no error messages whatsoever.
I monitored the processess and event log - basically it seems that asp.net worker process is generating errors until it stops working. And I can’t figure out why. All should be fine on SQL Server 2008 side, all protocols enabled, even disabled firewall; i can connect to the instance using Management studio from the same server (64bit) and from other development machines (64bit/32bit).
Then i tried using the web application from my development machine (still Vistual Studio 2003 one, i.e. 32 bit with ASP.NET 1.1) and connect to the new SQL Server 2008 and i got „Server application unavailable“ error. Same thing happens, worker process is generating errors until it stops working.
I used IIS Diagnostic Tool to debug the moment the error occurs – all i got was basically unlimited numbers of „First chance“ exceptions (problems with msvcr80.dll, mscorwks.dll). If I limited the number of those, I also managed to get „Kernel32!TerminateProcess“ exception, which after analysis stated that it didn’t detect any problems with that; only one time i got the warning, describing that 1 client connection was executing for more than 90 seconds.
I dont think the problem is on the 64bit Windows server 2008 or SQL server 2008 side, since when, just for checking, we used Sharepoint application with the new SQL Server 2008 as database, it connected just fine.
So what am I missing with our ASP.NET application configuration/development that it cannot connect to 64 bit Sql server 2008?
Thanks and regards,
Martin.
This sounds like a configuration problem, probably a permissions problem. Your Sql Server is on a different box than the your web server? If so I would look at what user your web site is running under. Make sure that user has access to the Sql Server.
If your user does have access make sure it has access to travel the wire to your SQL Server. Try to connect to the SQL Server via Sql Management Studio with the user's credentials.
