SQL Server Express Connection Trouble
Sep 29, 2006
I am trying to connect to SQL Server Express using the following VB code from an aspx.vb page: ' Create and open a connection to the database
Dim conn As New SqlConnection("Data Source=YOUR-FE632222CE\SQLEXPRESS;Initial Catalog=scotfree;Integrated Security=SSPI")
conn.Open()
This code fails on conn.Open() however giving me the following exception:
System.InvalidOperationException: Instance failure.
Stack trace:

Here is the way SQL Server 2005 Express is currently setup:
SQL server has IP of 192.168.8.200. (DMZ zone - 192.168.8.*)
Web server has IP of 192.168.8.81. (DMZ zone - 192.168.8.*)
My workstation has IP of 192.168.1.100. (Trusted zone - 192.168.1.*)
So, I've been developing a web application that was stored in the trusted zone, and this application didn't have any problem connecting to the database on *.8.200. I even have SMSE running and I can manage the database without any connection problems. I moved the web application to the web server, without changing the web.config file, and now it will not connect from the webserver.
In the web.config file, the connection string is pointed to 192.168.8.200SQLEXPRESS. I'm confused because it seems that since the SQL server and the Web server are in the same zone, there shouldn't be any connection problem.
In the Firewall, I have port 1433 open for TCP/UDP for ANY -> ANY...so I think the firewall is configured correctly?
Please advise! Thanks!

Well here is my connection string, I used these details to succesfully access the server from mySQL gui.
SqlConnection shhfd = new SqlConnection ("Data Source=http://www.mydomain.co.uk; " +
"user id=mteccles; password=mypass; connection timeout=30; "
then... try { shhfd.Open(); blah blah blah.
The exception caught is as follows.
at System.Data.SqlClient.ConnectionPool.GetConnection(Boolean& isInTransaction) at System.Data.SqlClient.SqlConnectionPoolManager.GetPooledConnection(SqlConnectionString options, Boolean& isInTransaction) at System.Data.SqlClient.SqlConnection.Open() at WebService1.Service1.HelloWorld() in g:inetpubwwwrootwebservice1service1.asmx.cs:line 120
My guess is that something in the web.config isn't right or maybe the host (webfusion) is strange. Thanks if anyone can help.

Hi I have Visual Studio 2005 with SP1 installed, and I want to install the Management Studio. I tried many times installing that and I always got the same problem, which is when I try to create a database in VS I just don’t get trough as I used to. A message appears saying that I’ve to enable some estance. So to resolve the problem I saw if is everything ok with the SQL Server, which seemed to be fine, but I couldn’t start the Report service.
Now I just formatted the computer and I’m afraid to happen all over again. May be the version with only the Management would be fine, I don’t know if it adds something beside of that.
Thank you very much.

Hi there, i have sometimes trouble to write data to a table in a sql server expr. database.
i have a vb.net application that writes every 2 minutes data to a table. sometimes (no regulary phenomen) the error appears after some hours, sometimes after some days. then i cannot write data in the table. it seems that the database sleeps or is offline.
before i write the data i check if the connection is open and i can write data.
if i cannot write the data i try several times and often after the third try i can write the data.
i have checked everything (no power save's on or other power off modes)
i have also test it with SqlClient.SqlConnection.ClearAllPools()
and many other things to find the bug, but no success at the moment.
it seems that the database or the table is away ?? or sleeps for some seconds ?!? i have no idea.
could you help me ?
Greetings Andreas

I am having trouble updating my database. I have seen a couple of other people had the same problem. Two answers I had found and tried did not work. The updating if newer I had already came across in a step by step class room tutorial written by a college professor and to make sure the save procedure came after the update procedure. I did need to make this last change but its still not updating. Any further advice on this subject would be appreciated.

Hello,
I've developed a desktop application for a company. It uses click once deployment and has a few prereqs: .NET Framework 2.0, j# .NET redistributable, windows installer 3.1 and SQL Server 2005 express edition.
Most of the time the application downloads and installs fine. However, one user has a problem. I'm fairly certain it's machine / OS related and I wonder if there is a way to get around it.
The user has a Windows 2000 machine, Pentium III, with 512 MB of RAM.
On their first try, they received an error while installing SQL Server 2005 Express. The error code the user found in the install log was 70095. Apparently the user found some information directing them to install the current MDAC 2.8 SP 1. After rebooting and trying the install again, it errored out. The new error code is 1706. Below is the install log.
As I said, I'm faily certain it's an OS issue, but I do hope there is a way around the issue other than trying to get the user to upgrade. If you need any other information, please let me know and I'll try to get it from the user.
Thanks,

Here is the information that I have... ( ps all information is not the actuall information )
1) URL abc.somehostingcompany.com IP: 211.11.111.1 PORT: 1433 ( NOTE: if I go to a cmd promt and type in ping abc.somehostingcompany.com I get a response )
2) dbname = mydatabase
3) userUid = sa pwd = sa
Inside SQL Server Configuration Manager --> SQL Server Network Configuration --> Protocols for SQLEXPRESS, I enabled TCP/IP and Shared Memory. Inside the properties of TCP / IP, I made sure under the "IP Address" tab that the
IP1: Active = yes
IP1: Enabled = yes
IP1: IP Address = abc.somehostingcompany.com
IP1: TCP Dynamic Ports = 0
IP1: TCP Port = < empty string >
I clicked "OK", and I stopped and started the SQL Server 2005 Services --> SQL Server (SQLEXPRESS). Then I started up SQL Server Brower.
Lastly I go to SQL Server Management Studio Express and try to connect to this remote server and database and I keep getting timeout issues and a message saying that the default settings for SQL Server Express do not allow remote connectioning by default.
Any ideas what I could be doing wrong? Should I use the port number instead of Dynamic Ports? Should I use the real IP address? Does the LOG ON AS under SQL Server (SQLEXPRESS) properties need to be updated?
Any help would be great.

Hi all,
I have a SQL Server 2005 Express edition instance set up on one server, and IIS on another server.
The SQL Server process account is a domain user account, which I have added to the local groups that SQL Server created during installation (I originally used a local user account instead of domain account; however, the problem occurs with both).
SQL Server runs fine, and if I set my IIS application pool identity to a domain admin, my web app can access the database and retrieve the data necessary.
However, I have a domain user account that I want to use to run the app pool and retrieve the data. The domain user account is added to the IIS_WPG group on the web server. On the database server, I have created a login for the account, as well as added it to the db_datareader role of the database that is used for the site.
However, the user is not able to connect to the SQL Server. I get the "Login failed for user <user account>" error in ASP.NET. I also tried connecting with SQL Server Management Studio, and I get the same error. I checked and the user has connect permission to the database server.
With admin accounts, there are no problems logging in, etc.
Any pointers are appreciated,
Thanks,
SA.
Edit: I was able to find out that the State is 11 for the error. According to http://blogs.msdn.com/sql_protocols/archive/2006/02/21/536201.aspx, this indicates "Valid login but server access failure." I am not sure how to resolve this.

Hi
I am installing Visual Studio 2005 Professional Edition. Everything goes well until the installation of SQL Server Express occurs. SQL Express installation progresses fine until very end of the installation. At that point it becomes stuck.
The installation says "Current component is installing" and is stuck on that message. The installer does not seem to be frozen as the picutres changes. However CPU usage for the setup processes is 0.
I have disabled all virus scanning software already.
Any help is apprceciated.

All --
Please help.
I have some questions about connection strings.
BACKGROUND...
Note that I am using the "SQL Native Client OLE DB Provider", SQL Sever 2005 Express, ASP.NET, C#.NET, and VS.NET 2005.
Note that I do not want to use the "Attach a database file" type of connection string.
Note that I am using the site http://www.ConnectionStrings.com as a reference.
Note that this "Standard security" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Uid=MyDatabaseUser;Pwd=MyDatabasePassword;" />...does not work and causes the following run-time error...A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)
Note that this "Trusted connection" connection string...<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Trusted_Connection=yes;" />...works but is less-than ideal because it uses a Trusted Connection rather than a Username/Password combination.
QUESTIONS...
(A) What exactly does the error in Item 4 mean?
(B) Do 4 and 5 imply that one must use a Trusted_Connection for all SQL Server 2005 Express connection strings when the database does not reside in the web application's App_Data folder or use a "Attach a database file" type of connection string?
(C) Are there any alternatives?
(D) What do you suggest?
Please advise.
Thank you.

Hello all,
I'm still having trouble connecting to SQL Server Express from a remote machine.
I read this article
http://blogs.msdn.com/sqlexpress/archive/2005/05/05/415084.aspx
and followed all of its steps. Remote access is enabled through TCP/IP and VIA. The ports are listening when I check netstat -a and netstat -abn on the server computer.
However, my client program still can't connect to the server.
Here is my connection string:
"Data Source=MACHINENAMESQLEXPRESS;AttachDbFilename=C:DatabaseDatabase.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True;Asynchronous Processing=true"
With this connection string, I can connect to the DB only on the server machine.
I've read something about the User Instance part of the string, but nothing really conclusive. All I know is when I have set it to false, I can't connect to the DB on the server machine either.
Not sure where to go from here...

I'm at a loss of where to go next and I need to get these guys rolling!
Next step is to reinstall drivers...but I'm doubting that is going to have any effect.
Thanks for any help

I'm developing an intranet site in ASP.NET 2.0 but I can't seem to connect to the DB from within my code. I've created a .vb class that houses a private Connection() that other functions within the class can call to connect to the database. In the calling function, I've declared my connection object and called the "Open" method on the object. However, when I attempt to execute the stored procedure command by calling the "ExecuteScalar" method, I get the following error:
"ExecuteScalar requires an open and available Connection. The connection's current state is closed."
Here's the code from my class:
Imports System.Data
Imports System.Data.SqlClient
Namespace Encompass
Public Class EncompassSecurity
Public Shared Function GetHRIDByNTUserID(ByVal strNTUserID) As String
Dim strHRID As String
'Create command object
Dim cmd As New SqlCommand("usp_Get_HRID_By_NTUserID", Connection())
cmd.CommandType = CommandType.StoredProcedure
'Open DB connection
Dim DBConnection As SqlConnection = Connection()
DBConnection.Open()
'Input parameters
Dim inNTUserParam As New SqlParameter("@NT_UserID", SqlDbType.VarChar)
inNTUserParam.Direction = ParameterDirection.Input
inNTUserParam.Value = strNTUserID
cmd.Parameters.Add(inNTUserParam)
'Output parameters
Dim outHRIDParam As New SqlParameter("@HRID", SqlDbType.Int)
outHRIDParam.Direction = ParameterDirection.Output
cmd.Parameters.Add(outHRIDParam)
'Run stored procedure
strHRID = cmd.ExecuteScalar()
Return (strHRID)
'Close DB connection
DBConnection.Close()
End Function
Private Shared Function Connection() As SqlConnection
Dim strConnectionString As String
strConnectionString = ConfigurationManager.ConnectionStrings("Conn").ConnectionString
Return New SqlConnection(strConnectionString)
End Function
End Class
End Namespace
Here's the code from my web.config file:

Hi all,
I followed an excellent tutorial (from Microsoft) about creating and using a SQLExpress db table internal to your website and the site I created works just fine - locally. When I publish to my web host provider I get this error:
[SqlException (0x80131904): 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)]
My web host provider supports .NET 2.0 but doesn't support MS SQL Server. But that should matter - right? Because I'm putting the db instance right in the website?
I did a search and followed some of the advice:
I went into the SQL Server Surface Area Config Mgr and set SQLExpress for local and remote connections and rebooted/republished. I also have SQL Server 2005 installed as a separate entity (if that makes a difference).
I still get the above error. This is the connection string from the web.config:
<connectionStrings>
<add name="ConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Customers.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
And this is the call from the markup:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT * FROM [Customer]"></asp:SqlDataSource>
Does any know the fix for this?
Thanking you in advance
Pat

Actually I should have said #22 but this is beyond the point. It seems the errors pop up and then go away for no reason, then appear again.
I had Sql Server Express with Advanced Features set up all right as far as I can see. It is the connection issue that is causing the headache.
Currently when I try to make a connection with an Sql database I get an error in Visual Studio:
Generating user instance in Sql Server is disabled. Use sp_configure 'user instances enabled' to generate user instances.
So I go to Sql Server, log in, open a new query and type:
sp_configure 'user instances enabled'
GO
I get a table where I can see that
name minimum maximum config_value run_value
user instances enabled 0 1 1 1
Are they enabled? I think, yes. I go back to Vsisual Studio and get the same error. It is possible that I will have to log out in order for all this security garbage to take effect and I will try it but in the meantime, how can I set more than one instance.
I want to complain that these new security provisions that came apparently with SP2 and Vista are totally unnesessary for my applications. I do not have any high security info to worry about, e.g. social security numbers, etc. I would not mind to turn all this stuff off if it is possible at all.
So, how can I set up 3 user instances?
Thanks.

When trying to install SQL Server 2005 Express, it hangs up on "Detecting Installed IIS". This happens if I have IIS installed, and if I do not. My computer is running XP Media Edition. I found a similar question asked by flashg on these forums, but there was no answer to the problem. There were a few other people who posted the same problem.
Is there any fix to this? I am writing software that I planned on using SQL Server Express to store its data with. But if SQL Server is going to cause problems on my customer's computers then I cannot use it.
This is the end of the log file for my SQL Server installation:

Hi,
I was trying to install visual studio 2005 and as part of it I wanted to install sql express as well. It installed the rest okay but not the sql express. Going through the log file I figured out that there was some incompatible beta version installed and hence had to be removed. In the log file I got the following error messages. Going through the forum suggestion I was trying to use msiexec /x to deinstall each of them but got the error message that "The setup has encountered an unexpected error in datastore. The action is Write_CommitFlag. The error is unable to write property into cache: flagCommit. Unable to write property into cache: "flagCommit" XmiRW Error: Failure loading xmlrw.dll CheckAllProcedures. returned 2". After this error message when I check the sql server configuration manager, I still see the old instances running.
I followed up another forum suggestion where I completely installed the old CTP and used the tool provided in the DVD(sqlbuw) to uninstall it but it only removes the one instance and leaves the rest on the system.
I will really appreciate help...

First off, I am fairly new to sql.
I've created an sql database in VB express, created some tables, and entered some data in those tables. My problem now lies with actually using that data. What i'd like to do is have a Sub use the database's data and fill in a series of variables. Right now i have the Sub using an Excel file to assign the information, looks like this:
Public Sub CharStatDefault() 'loads each character's default stats
CharSheet = xlBook.Worksheets(2)
P.initialize()
For excelInt = 1 To 22
P.C(excelInt).Initialize()
With P.C(excelInt)
.Vit = CharSheet.Range("AC" & excelInt).Value
.Phy = CharSheet.Range("AD" & excelInt).Value
.Mag = CharSheet.Range("AE" & excelInt).Value
.Off = CharSheet.Range("AF" & excelInt).Value
.Def = CharSheet.Range("AG" & excelInt).Value
.Agl = CharSheet.Range("AH" & excelInt).Value
End Sub
So basically i want to change the CharSheet.Range("XX" & excelInt).Value to something that utilizes the data from my database.

Hello, I'm using Visual Studio 2003 and I need to be able to connect to an SQL Server 2005 Express database on the same machine using ASP.NET pages, but I'm having difficulty getting the pages to make a connection.

hello. after deployment my SSIS code to a different server - I get the following error:
"The file name "C:\Documents and Settings\Administrator\Desktop\filename.txt" specified in the connection was not valid.
"
This is a flat file connection - and the file does in fact exist - but the difference is that I'm running the DTS package under a different account.
I would like to set the flat file connection to run under a different account - can I do that? Is that the "Creator" property?

I am creating an install for our product and as part of the changes I
am making, I want to upgrade a user's DB engine, if they are still
using MSDE 1.0, to SQL Express 2005.
The upgrade path we have chosen is the following.....
MSDE 1.0 --> MSDE 1.0 sp4 --> SQL Express 2005
I believe this should work, yes? Anywho, I am trying to run a
"passive" install of SQL Express and I am using the following parameter
list:
/qb
UPGRADE=SQL_Engine INSTANCENAME=MSSQLSERVER ADDLOCAL=ALL
DISABLENETWORKPROTOCOLS=0 SECURITYMODE=SQL SQLAUTOSTART=1
SQLBROWSERAUTOSTART=1 SQLACCOUNT="NT AUTHORITYSYSTEM"
SQLBROWSERACCOUNT="NT AUTHORITYSYSTEM"
When SQL Express is installing, everything installs properly except the
backward compatibility component....any idea why this is happening?
I'm certain that some of the above parameters (in red) are wrong because if I install all the engines (above in blue) manually then it all works.
Thanks

This is my first post ever so forgive me if this is too basic a question.
I have an Access 2000 database that I'm trying to make into a SQL 2005 Express database. Both databases are on the same machine (I've given up with the networking of this) and, after straightening out several problems I've ran into one I can't seem to fix.
Using the Upsizing Wizard in Access 2000 I try to connect to SQL 2005 Express but I keep getting this error: http://www.paulmauer.com/SQL%20connection%20error.doc
SInce both programs are on the same machine I don't understand what is happening. Any help would be appreciated.

Hi,
I am relatively new to this. I have installed VB 2005 and that has installed a version of SQL Server 2005 Express on my local development machine. I am using VB to develop some demo sites and i can create DB's in the App_Data file and they work when I test and run then by pressing Ctrl + F5.
However i have some demo tutorials that require Northwind and Pubs to do them. So i have installed Northwind and Pubs using the cms prompt and the InstNwnd.sql install. They said everything has been installed fine.
This is where the problem starts. I open new connection in VB, or asses for that matter and try to open my local server machine (just my desktop running WindowsXP pro), Which is called Optiplex. Sometimes i get the optiplex appear in the dropdown that asks for your to choose a server and other times it doesnt. Eevn if the machine appears it doesnt let me chose Pubs or northwind from the second drop down.
I think i must have SQexpress running on the machined named Optiplex because i have the SQL server configuartion manger on it. That tells me i am running SQL Server(SQLEXPRESS) and SQL Server Browser both switched on and running. By the way i have set my SQL manager to run as Local service.
One thing that i consider strange is that when i have had SQLServer Express running on other machines normally there was a little icon running in the right hand corner of the the task bar.
Does anyone know what is going on with my mchine and have i got the SQL server setup correctly?
Just one last piece of additionally information is that i have a folder called C:SQL Server 2000 Sample Databases which is where the MDF files are located.
Thanks a million Sanson

I´m developing an application for PDA that have to connect with a SQL server running SQL espress 2005. First I
coded the app to run on the server machine in windows forms and works fine. Then I coded the app under compact
framework in order to run on a remote PDA and I have connection problems. I´m doing test with visual studio
emulator running in the same computer that sql server is.
I configured sqlserver to allow remote connections and use tcp/ip and named pipes.SQL browser is running too.
The firewall is disabled. I´m using windows auth. I used different users, used different connection strings but
I can´t connect to the server. I have read this configuration web:
http://blogs.msdn.com/sqlexpress/archive/2005/05/05/415084.aspx
The last connection string I used is: Server=192.168.0.3;Initial Catalog=dbase;User ID=guest;
In the connection string I added port 1433, servername instead IP, different users id...but can´t connect.
I can ping visualstudio emulator from sql server, now are in the same lan but in future pda have to connect to
server using gprs.
Where is the error??
Thanks in advance.
PS. I´m reading some post that indicates SQL Server Express doesn´t allow any remote connection?

I am having trouble connecting to SQL Server 2005 Express using ASP.NET written in VB.NET (1.1 Framework) in VS2003. I am trying to programmatically connect to the SQL Server. Since this is a redistributable web application and I don't want to rewrite the connection string every time I distribute a copy, is there any way to automatically get a connection string without prompting the end user for one? I can get the server name and the data base name, but I don't know how to get a username. It returns an error saying SERVERASPNET can't log on. Can anyone help?

I am using SQL server express 2005. I can drag and drop a grid control on to my web form and choose the data source to point to a SQL server database. Then datais nicely displayed on my web form.
Now I need to manually create my connection to the database as I need to read from a text file and then populatea database table with those values I read from the text file. I have not had any success with this though and I am stuck and need some help.
Below is my C# code and I list the web.config code where my connection string is stored.
Note that I can trace into the C# line of code below. If I then do a "Quick Watch" on "myConnection" in the debugger, the followingerror message is displayed:
ServerVersion 'myConnection.ServerVersion' threw an exception of type 'System.InvalidOperationException' string {System.InvalidOperationException}
So I don't know what the problem is here. If someone can help me out I would be forever thankfull
C# code:
SqlConnection myConnection = new SqlConnection(ConfigurationSettings.AppSettings["TheDividerConnectionString"]);
Here is the connection string as defined in the web.config file:
<connectionStrings> <add name="TheDividerConnectionString" connectionString="Data Source=BVCOMPUTERSQLEXPRESS;Initial Catalog=TheDivider;Integrated Security=True" providerName="System.Data.SqlClient" /> </connectionStrings>
