<!--

<remove name="website_connectionstring"/>

Failed To Generate A User Instance Of SQL Server Due To A Failure In Starting The Process For The User Instance - Vista Business

Feb 20, 2007

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.

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

How To Fix Failed To Generate A User Instance Of SQL Server Due To A Failure In Starting The Process For The User Instance

Microsoft Visual Basic 2005 Express Edition

OK

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.

Failed To Generate A User Instance Of SQL Server Due To A Failure In Starting The Process For The User Instance

Mar 12, 2006

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?

SQL Server 2005 Instance Connection Failure

May 18, 2007

This has me totally baffled. I have a default instance of SQL Server 2005 on a server and I installed a second instance on the same server. It worked fine until I rebooted the server. Now I cannot connect to the second instance. The error message mentions remote connections but I'm not trying to connect to the instance remotely. The entire error message is below. Has anyone come across this?



===================================

Cannot connect to SERVERINSTANCENAME.

===================================

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: TCP Provider, error: 0 - No connection could be made because the target machine actively refused it.) (.Net SqlClient Data Provider)

Failure In Starting The Process For The User Instance

Apr 13, 2006

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.

When trying to create a new Integration Services Project and start work in the designer receive the MICROSOFT VISUAL STUDIO 'Object reference not set to an instance of an object.' dialog box with message "Creating project 'Integration Services project1'...project creation failed."

I'm not finding any information on corrective action for this error.

Any one have this problem and found the solution?

Failed To Generate A User Instance Of SQL Server Due To Failure In Retrieving The User's Local Application Data Path

Jun 21, 2005

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.

SQL 2012 :: Clustered SSAS Unable To Connect To Named Instance (instance Not Found On Server)

Mar 20, 2014

I have a 3 node cluster on which I have installed SSAS as it's own insntance. I have created this as a named instance and can connect to it by serverinstance if I'm on the server itself. However from my desktop I get the error saying instance was not found on server name.

I have defined an alternate port and setup firewall rules and can connect via server:port but not serverinstance. Prior to making this change SSAS was running on default port of 2383 and I could connect just by servername.

I have read many articles for previous versions saying that clustered SSAS will always use 2383 and that you must connect just using servername. However and this is were it gets strange. I have a 2 node UAT cluster with SSAS setup exactly the same way I've described above and I can connect from my desktop as serverinstance.

Should I be able to connect as serverinstances for a named clustered instance in 2012 ?

Migrating From SQL2K Named Instance To SQL2K5 Default Instance

Feb 19, 2007

Hi, I have a task in hand to migrate (upgrade) from SQL2K named instance to SQL2K5 default instance. There are many intranet applications touching current SQL2K. I would like to perform this upgrade such that I don't have to touch any application code - meaning I don't have to change the connectionstring to point to new Default instance. How can I achieve this?

So, in otherwords, here is what I want to achieve:

Current Server: SQL2K: SERVER_AINSTANCE_A (named instance)

Upgraded Server: SQL2K5: SERVERB (default instance)

If I have both default, I could achive this by setting up DNS alias after migration done so that any call for SERVER_A would point to SERVER_B. But in my case, I don't have SERVER_A, I have named instance. Is there any solution?

Regards,

Vipul

How To Move A Single Database From SQL Server Instance To New SQL Instance

Jan 13, 2007

Hi,

I want to move one database from the source SQL Server 2000 instance to a new SQL 2000 instance in another machine. I have five user databases in this source SQL instance. How should be my approach to move this single database out of this ? My understanding is restoring this database in the new instance, copying all logins to the new instance and then copying the jobs, DTS packages, alerts, operators only specific to this database will do it. Please let me know if this is exactly what I should do ..

Thanks in advance..

Named Instance Problems (Default Of 7.0/2000 Instance)

Oct 10, 2001

I am trying to set up a Named Instance of SQL 2000 on the same machine that has a default instance of SQL 7.0. The setup always completes and I am able to register the Named Instance of the SQL Server with which it was installed on. However, when I try to connect the users to the database, with both windows and SQL authentication, I receive a SQL server not found error.

Move SQL2005 From Default Instance To Named Instance

Mar 2, 2007

I have a server with sql server 2005 installed as the default instance -- I have a piece of software that needs SQL2000 to be the default instance. Is there a way other than install new sql2005 named instance and move databases to rename my SQL2005 instance from <machinename> to <machinename>sql05 for example?

Installing A Default Instance AFTER A Named Instance???

Aug 24, 2006

I have SQL Server 2000 Standard Edition (sp3a) running on a windows 2003 (sp4) Server.

It is a Production Server with 3 NAMED Instances and NO Default Instance.

Does anyone know if I can rerun the SQL Server Install and add a DEFAULT Instance to this box without disrupting the other Named Instances???

Single Instance/Multiple Instance/Virtualization Q

May 17, 2007

I work for a mid size company with the usual collection of enterprise applications. We are trying to consolidate our SQL environment consisting of around 100 databases none of which are over 100GB with the average database size around 5GB. Recently a large server was purchased as the "Big Daddy" SQL box. Obviously not all the databases will be moved to this one box but within reason a number can.

My question: What is the best way to configure the box?

1 OS & 1 Default Instance - How do we isolate loops memory leaks etc...
1 OS & Multiple instances, ie:Dedicated instance for each application. - How do you allocate CPU & memory, allow for optimum performance without putting others at risk from a rouge process?
Virtualized OS for each application with a default instance - Too much overhead impacts performance?

Future plans include offsite replication, perhaps mirroring with failover.

I'd appreciate anyone else's thoughts ideas? How have you tackled this problem in your environment?

Thanks
Scott

Migrating From Named Instance To Default Instance

Oct 30, 2007

I installed SQL Server 2005 recently on a cluster. I didn't go for the default instance and instead I named the instance option. Now I would like to migrate everything from the named instance to the default instance, which I haven't yet installed.

Is this an easy process? What about the logins and the maintenance plans and jobs? Is there anything else I need to be aware of?

Create A Named Instance On Top Of A Default Instance

Apr 13, 2007

Hi

I've never had to do this, but when I downloaded the Web Workflow Approvals Starter Kit, it requested that I install the database into a User Instance of .SQLEXPRESS.

Now the problem is, I've installed it onto a default instance, so I was wondering whether you can create a named instance on top of a default instance... and if so, how would you do that?

Cheers

Chris

Connection String For Default Instance Of SQL Server 2005, On A Box Also Running A Named Instance Of SQL Server 2000

Nov 15, 2007

The box I am trying to connect to is running two instances of SQL Server.
There is a SQL Server 2005 instance which is the default. There is a SQL Server 2000 instance which is named 'SQLSERVER'.
 I can connect to the SQL Server 2000 instance no problem:<add key="ConnectionString" value="server=MYPCSQLSERVER;database=mydatabase;user id=****;password=****" />
However,  I am having trouble connecting to the Default SQL Server 2005 instance. I have tried:
<add key="ConnectionString" value="server=MYPC;database=mydatabase;user id=****;password=****" />
 but it doesn't work. I have tried explicitly setting SQL Server 2005 to use port 1434 (as SQL Server 2000 is running on port 1433), and then used:
<add key="ConnectionString" value="server=MYPC,1434;database=mydatabase;user id=****;password=****" />
but this doesn't work either.
 
Am I mssing something here? Any help much appreciated
Thanks...

 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.
