Failed To Generate A User Instance Of SQL Server Due To A Failure In Starting The Process For The User Instance
May 25, 2006
Hello everyone,
I am new in .NET development and currently trying to learn VWB through Microsoft online tutorials.
Here is the problem that prevents me from getting further:
in VWB, when you right click App_Data and chose "Add New Item" and then select SQL database, the following error message is displayed:
"Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed."
If I cancel out of it, it does generate mdf file under App_Data folder in Solution Explorer, but when I try to open it, it says:
"The item does not exist in the Web directory. t may have been moved, renamed or deleted." and that is where the whole sharade deadends.
I can connect via mycomputersqlexpress under Data Connections in Database Explorer (it then adds "master.dbo" to the path) and then create custom tables, but that is not the same, isn't it? I mean, this will not integrate my database tables through default configuration that I am trying to follow?
All this happens on local machine.
Thanks to everybody who can help!
Jeff

Got windows Vista Business edition, installed Visual Web Developer Express, SQL Server 2005 Express SP2, SQL Server Management Studio SP1 in that order. I was developing in VWD express without problems using WinXP but now on Vista Business, the local connection to SQL server appears to be a problem.
I know there's nothing wrong with my web.config or anything like that as it was working perfectly prior to running under Vista. If i specify the database on the live website, it works fine. If I specify the test database in app_data folder, I get the following exception:-
Server Error in '/UKSD' Application.

I am taking a guess it's somerthing to do with access issues, but can't find anything out on searching the forums etc..
I am setup as an administrator, running VWD as an administrator and for the record, SQL Server Management Studio express works fine.
Another small issue, when I run the application from VWD, I always have to minimise the application and restore it as the graphics get corrupt.
Please help!! I cannot debug when running of the live website.

I was able to do do this before until Saturady when I had to re-install sql server, and express etc due to some system problem on my xp Pro PC. What have I misconfigured?
I do see the service SQL Serer(SQLEXPRESS) started under Network Service and SQL Serfver(MSSQLSERVER) started under local system.
My power user ID does have modify access to the sql 90 database folders. and to the mdf.

No wonder Microsoft is giving it away for free. It€™s not worth anything. I am very disappointed in this version of SQL server. I decided to start learning VB so I downloaded and installed VB 2005 express edition and SQL 2005 express. I tried to build a personal website using the starter kit. I kept getting the following error message, for which I have seen numerous postings on this forum.
€œFailed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.€?
I went out and bought the Standard version of VS 2005 thinking there may be a feature that the free express version is lacking. I uninstalled the express version, cleaned the registry, deleted all the folders it created and installed the Standard edition. Then I tried to create a personal web using the starter kit and it does the same thing again.
I can not create a database file, connect to a database file. I can not create or attach a database on the SQL 2005 express from VS 2005. The SQL server Express seems to be working OK since I can attach to it using Microsoft SQL Server Management Studio Express. There is something about the way VS tries to connect to the database server that is not working. VB does recognize the local computer as a SQL server but can not connect to it.
SQL server is set to accept Shared memory, TCP/IP and named pipes for local clients.
What is causing this?
This is some information on the system I am using:
MS XP (SP2)
Microsoft Visual Studio 2005
Version 8.0.50727.42 (RTM.050727-4200)
Microsoft .NET Framework
Version 2.0.50727
Installed Edition: Standard
Microsoft SQL Server Management Studio Express 9.00.1399.00
Microsoft Data Access Components (MDAC) 2000.085.1117.00 (xpsp_sp2_rtm.040803-2158)
Microsoft MSXML 2.6 3.0 4.0 5.0 6.0
Microsoft Internet Explorer 6.0.2900.2180
Microsoft .NET Framework 2.0.50727.42
Operating System 5.1.2600
I am now to programming but nor computer illiterate. I have been working with MS SQL servers since version 6.5 and have MCSE, Network+, A+ and Security plus certifications. Installing and using VS should not be this problematic. What is wrong with Microsoft?

Hello everybody,I was configuring a SqlDataSource control using SQL Authentication mode.I first added a database file (testdb.mdf) through Solution Explorer-Add New Items. Then through Database Explorer I created a table named "info"Then while configuring the SqlDataSource control I used the SQL Authentication mode and attached the "testdb.mdf" database file.Test Connection showed success. But when I hit the Ok button of the wizard it displayed the following error message:Failed to generate a user instance of SQL Server. Only an integrated connection can generate a user instance.While configuring the SqlDataSource control I clicked "New Connection". Under Data Source section I tried both Microsoft SQL Server and Microsoft SQL Server Database File. And in both the cases I attached a databese file(testdb.mdf). Plz enlighten me on this.Thanks and Regards,Sankar.

Hi all hope some one can help - please bear with me new to this
Basically I have had to change pc's so I copied and pasted my ASPNET.MDF and LDF from my old pc to new PC including webpages/apps etc.. created.
However now all I get is "Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path """"

I installed my asp.net 2.0 web application and sql express june editon on my windows 2003 server.When the application tries to reach the database i am getting the following error"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."I can understand that it has something to do with user right but more than that I am pretty lost. Can anyone translate this error for me and give me some tips on what do to.I checked first the user running the sql express service and saw it was the NETWORK SERVICE user. I changed it to be the local system account but that did not make any difference. The application is running just fine on my local computer(Win XP sp2). This one has SQL express April edition though.

High everybody,
I have a set of winforms (.NET 2.0 assemblies) ( 6 total ) that each tries to open a connection to the same Database file using the same connection string. In the connection string, UserInstance is set to true.
If each winform is started manually after opening the session on the computer, the connection to the database performs well for every winform.
If the same winforms are automatically started at the opening of the user session, the the following error is reported by each application when trying to open the connection :
Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.
The only way to overcome this problem is :
to stop the winforms, to stop the SQLExpress service, to kill the remaining sqlserv.exe running task, then restarting SQLExpress service, and finally manualy start the winforms.
Any help would be greatly appreciated.

I use VS2005 & sql2005express to create a website, but it cannot to display data.
When I run it, I got such errors:
Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.
My web.config file:
<add name="LocalSqlServer" connectionString="Data Source=.SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|aspnetdb.mdf"/>
When I change the User Instance=True to False, it works, but MSDN says it is not safe.
I searched the past threads, which writes "delete the folder C:Documents and SettingsyyLocal SettingsApplication DataMicrosoftSqlserver Data, it will work".
I try, but failed. What should I do??

I have seen many posts on the subject, but I haven't seen a clear answer to the following:
1. Start a new Web Project (VS 2005 Pro). The solution is built.
2. Select App_Data, right click and select Add New Item.
3. In the dialog box, select SQL Database and give it a name.
4. When you select Add, the message "Failed to Generate User Instance of SQL Server ... " appears.
5. I am running SQL Express. What is the correct fix to get this simple process to work?
thanks,

I have SQL Server 2005 SP1 Dev Edition installed on my laptop along with Visual Web Developer 2005. I installed SQL Server Express 2005 SP1. I then created a new web site using the Club Web Site template.
I did the recommended initial build to get the Membership database installed and got an error page (http://localhost:1667/WebSitesVB2/):
SQLExpress database file auto-creation error: Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.
There were 4 recomme4ndations from the error page. I have met three of them: (1) the AppDaa folder that was created when I used the Club Web Site template; (2) my machine's ASPNET user set up with full control permissions on the APP Data Folder; (3) SQL Server Express successfully installed on my machine.
The 4th recommendation from the error page is "The process identity for the web server account must have a local user profile. See the readme document for details on how to create a local user profile for both machine and domain accounts. ". I have no idea of how to do this or how/where to find the elusive the "readme" file.
I am at a loss as to what to do next. I have spent the day going over forums on this error and none seem to provide consistent or relevant answers.

Hi,
I am using a logon control on my site that is supposed to display an erro message when user id or password is wrong. Instead, when I enter the wrong password, I get:
Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.
when I trace the code, I see that the loginbutton_click event gets fired, it failes to validate the user id/password by checking DB, and sets the error label's text property to the error message and the dies with the above error message.
I appreciate your help.

I wrote an application using Visual Studio 2005 beta 2 which uses a SQL Express .mdf file, included in the project, for the database. After installing Visual Studio 2005 RC and the SQL Express that comes with it (I followed all of the uninstall instructions first) I can no longer add a SQL Express database to any of my projects, nor can I open the SQL Express database in my original project. When I try either of these tasks, I get the "Failed to generate user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed." I read the thread which dealt with this error, and changed the connection string for the database file that had worked before to User Instance = false. The moment I click Test Connection or OK, I get the error: "An attempt to attach an auto-named database for file C:<path to project>EngSQL.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share." (<path to project> is actually a full path, I didn't want to type the whole thing out. :) ). A search for this error turns up a solution of setting User Instance = false, which puts me in a catch 22 position.

I've set up a website on another computer using sql server express and visual web developer express, and it works as expected. However halfway through the development i've had to move to another computer. I installed visual web developer express + sql server express, and copied the project files across, but now when I attempt to run it I get the error:Failed to generate a user instance of SQL Server due to a

will be closed. I've tried reinstalling the software and it doesn't help. Any idea why this is happening, and what I can do to fix it?thanks

We are looking at developing an SQL Server 2005 Database and I would like to use Windows Authentication rather than SQL Server Authentication to connect our client app.
In our development environment, we have two Servers, one being used as a file server and the other as an SQL Server. We have now set up a domain using the file server as the domain controller. (We had previously been set up to use a workgroup).
I have set up an active directory group called SqlDevelopers and added an active directory user called Jonathan to it.
On the SQL Sever, in management studio, I have set up a new server login which uses windows authentication called DomainSqlDevelopers. I used the GUI to verify I could see the domain and the group.
The default database is set to a test database on the server. A user in the test database is mapped to the DomainSqlDevelopers and given the Roles dbo, db_datareader, db_datawriter.
To test the log in, on the server, I logged out as administrator and in as Jonathan. I could successfully access the server through management studio using windows authentication.
However, if I log in as Jonathan on my client PC and try to access the SQL Server using management studio and windows authentication, I have problems.
The first time I try I will get a timeout error. If I try again will get either:
Login failed for user ''. The user is not associated with a trusted SQL Server connection
Or
Cannot generate SSPI context
I can€™t determine any pattern to which of the above errors I get.
However, if I log in as administrator on my client PC, I can connect to the server using management studio and windows authentication.
Sounds like Active Directory/Domain or other Network issue (Not really my area). I would be grateful for any help.
Thanks,
Jon

I'm using the RTM version of Visual Studion 2008 and SQLServer Express.
Logged in as an administrator, I can create a connection to an mdf file and all is well.
As a normal user, attempting to create a connection gives the message "sqlservr.exe has stopped working A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."
I have tried this with UAC turned on and turned off. The result is the same. In Services I can see that SQLEXPRESS is running, but each time I try to connect, I get the "stopped working" message.
For existing database programs that have the .mdf file stored in the project folder, I can run the program in the VS IDE on my XP machine and on my Vista machine as administrator, but not as a normal user.
I'm not looking for a workaround to make this work once, but the cause and solution to the problem. This is for an introductory VB textbook and we must be able to move a database program from one machine to another and make it work. Everything I have read says that SQLExpress should be able to do that.
Can anyone help me with this?

I was wondering whether anybody could confirm an assumption for me. The information on SQL Server Express talks a lot about its special "User Instance" mode and how it can help to simplify deployment because you can go back to just copying in a file to set up your database, and how this is great for dealing with limited user security environments. However, I have some questions surrounding whether or not this is really as great as it's cracked up to be -- I saw somewhere, for example, that made it sound like you have to be coding your application in .NET in order to use it; and it sounded like it pretty much gives the end user full access to their personal SQL Server instance, which I might not necessarily want from an application perspective. The assumption that I wanted to confirm was this€¦ Let's say that you're NOT using the "User Instance" mode. What do you then need to do in order to create the initial shell of your application database at deployment time? I was assuming that you end up having to have some sort of SQL script that does the database creation instead (including, I assume, assigning proper rights to tables to BUILTINUsers as necessary). Is that correct?

Is there a way to re-index a SQL Server Express User Instance? If I try to open the .mdf while the website is still running, I get a message stating that the file is in use. If I shut down the web service and open the .mdf, then restart the website, then the website cannot access the .mdf while I have it open in VStudio (reminds me a lot of Access).
In the past I tried to open a user instance with SQL Server Management Studio, but then it goofed up my user-instance...so I am hesitant to try that again. Is there any way to re-index?
Thanks!

Hello, I'll try to make the description of this multi-problem scenario as short and sweet as possible.
First Problem
The default named instance of "SQLEXPRESS" was somehow installed on my machine and nothing can get rid of it. However, it is somehow invisible to everything else on my system, so I can't use it. How do I get rid of the instance or repair it?
Second problem
I installed another instance of the SQL Server 2005 Express and named it, "SQLEXPRESS02". I attached a database to it and successfully retrieved data from it using an application that used the following connection string:
Data Source=(local)sqlexpress02;AttachDbFilename=|DataDirectory|MyDatabase.mdf;Initial Catalog=MyDatabase;Integrated Security=True;User Instance=True
Next, I tried to use a different application to retrieve data from a copy of the same database located in a different directory and used the same connection string as that shown above. When I do this, I receive an error message similar to the following:
Database 'C:PathToMyOriginalProjectinDebugMyDatabase.mdf' already exists. Choose a different database name.
Cannot attach the file 'C:PathToMyNewProjectinDebugMyDatabase.mdf' as database 'MyDatabase'.
I then tried, out of curiosity, to change the Initial Catalog portion of the connection string to "MyDatabase2" and attempt the data retrieval again. The connection string looked like this:
Data Source=(local)sqlexpress02;AttachDbFilename=|DataDirectory|MyDatabase.mdf;Initial Catalog=MyDatabase2;Integrated Security=True;User Instance=True
Interestingly enough, it worked. However, when I switched back to the original connection string, I got the same error message as before.
What's going on here? I thought that one of the virtues of user instances was that they would attach at run-time, then disconnect when the application was through with them. If that's the case, then why am I getting errors stating that a database of the same name is already attached? Is there a way to detach these databases from a user instance? Can it be done by some value in the connection string?
Thank you in advance for your help.

ProblemWhen Remote Desktop to my main office machine, and when trying toconnect to SQL Express, I was becoming increasingly frustrated with thefollowing error:Error: 'Failed to generate a user instance of SQL Server due to afailure in starting the process for the user instance. The connectionwill be closed.'What is the solution?Solutions: ( pick any of the 3)1. Obtain and apply the patch http://support.microsoft.com/?id=8966132. Wait for the next Windows Service pack3.Of course if you can not get the patch, you can always do this (Note:You must have WinVnc server running in your remote computer)1. In the remote desktop session, reboot your computer.Click Start->Windows Security->Shutdown->Restart.Wait for some time to get machine up.2. Use your vncviewer to login to your remote computer. You can chooseto do all work via VNC or go to next step.3. Use remote desktop to login (this automatically closes the winvncsession).There you go, You did not create a remote session, but reused yourlocal session.

Hi,
I have been working around with SQL Server Express 2005 on VISTA. I created a small C++2008 application which interface with SSE 2005. When running my application, it automatically created a user instance which I would like to get rid of. I just forgot from start to set "User Instance = False" in my connectionstring. (oups...)
I'm aware, from readings I did, that a couple of tables as well as log files, etc. are created under directory "utilisateurs...AppDataLocalMicrosoftMicrosoft SQL Server DataSQLEXPRESS". SQLEXPRESS is the instance name chosen during install of SSE2005.
Also using following SQL Statement:
select owning_principal_name, instance_pipe_name, heart_beat
from sys.dm_os_child_instances
I got following result:
owning_principal_name: PC-DE-STEPHANEStéphane
instance_pipe_name: \.pipe6172F4E8-622E-4A sqlquery
heart_beat: dead (at this moment...)
==> How can I make a good cleanup of all this as well as get rid of the user instance itself?
Thanks in advance for any help.
Stéphane

i'm using the Enterpirse library logger to write logs into a database.
When choosing connection string i choose the database i want in the "connection properties" dialog box and
push 'Test connection' button.
everything goes well.
then i open the SQL Server Management studio express and connect to the databse to check some things,
from that point on , when i push the 'Test Connection' button in the Enterprise library i get the error:
"cannot open user default database. Login failed. login failed for user My'server/MyuserName'"
even when i close the sql server manager , it is still stuck - the connection test doesn't work anymore....
it only work when i restart the computer.
why ?
