Sql Server Express And VB.net Express - Unable To Connect...
May 31, 2007
Hi!
I'm trying to connect a DB in SQL express with a program in VB.NET Express. I'm using the Data Source Configuration Wizzard. When I select the file (.mdf), the following message appears:
Unable to open the physical file "path to my file". Operating system error 5: "5(error not found)".
An attempt to attach an auto-named database for file 'myFile' failed. A database with the same name exists, or secified file cannot be opened, or it is located in UNC share.
I'm using the Windows authentication for this, but if I try with the sa user, I get the following message:
Failed to generate a user instance of SQL Server. Only an integrated connection can generate a user instance. The connection will be closed.
Any ideas to solve this?
Thanks

Hi, I am trying to connect with Database.mdf(Server Express) which is inside App_data with my ASP.NET website but i am receiveing an error which i have pasted below. Initially i tried using a business Object(.xsd) but while specifying the datasource in DataSourceobject i got nothing using wizard(which lists all the Adapter Methods(insert,select) of my business object) hence i am trying to connect without a business object. i.e just using the connection string(ConnectionStrings:DatabaseConnectionString) but this results below Error. Kindly help:; ------------------------------------------------------------------------------------------ Server Error in '/MapSpeaks1' Application. -------------------------------------------------------------------------------- Unable to open the physical file "c:inetpubwwwrootMapSpeaks1App_DataMapSpeaks.mdf".

Hi,
I installed Sqlexpress server 2005 and am able to connect to the server using the sqlexpress manager.
The connection parameters are:
server: 127.0.0.1 (This is an alias name pointing to TMD03SQLEXPRESS)
username:sa
password:test
mode: sql server and windows authentication mode
TCP/IP : enabled and listening on port number 1433.
But I am not able to connect to the server using PHP's mssql_connect function.
I tried various combinations like
mssql_connect("127.0.0.1","sa","test")
mssql_connect("local","sa","test")
mssql_connect("localhost","sa","test")
mssql_connect("TMD03SQLEXPRESS","sa","test")
mssql_connect("127.0.0.1,1433","sa","test")
but none of them works. I also tried OSQL and SQLCMD and they don't work either. They give me the following error message.
[SQL Native Client]Named Pipes Provider: Could not open a connection to SQL
Server [2].
[SQL Native Client]Login timeout expired
[SQL Native Client]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.
Can anyone please let me know what am doing wrong here?
Regards,
Celia

I have read all of the posts regarding this subject as well as 3"Dummies" guides and I keep having the same problems. I have a verysimple multi-user application that has to hit a database. Wecuerrently have this system deployed and it is working fine on adomain based network. We are scaling back and the network we will beusing is now a workgroup not a domain.It should be simple. I have XP boxes (clients) trying to hit the SQLServer Express database on a Windows Server 2003 machine. It is aclosed network so security is not an issue. I am trying to make thisthing wide open. All I want is for the user to be logged in on hisclient machine, run the application, and access/update the databasewithout having to re-authenticate to the SQL server. I want windowsto handle all of the authentication between the XP machines and theServer 2003 machine.Any suggestions would be greatly appreciated.

My situation: I have one virtual folder on a customer's server that hosts a web service which connects to Sql Server Express. This has been working for months.
The connection string that i use is:
(obviously the names have been changed to protect the innocent)
User ID=auser;Password=apassword;Initial Catalog=acatalog;Data Source=0.0.0.0SQLEXPRESS
I have recently added another virtual folder to the server, and it needs to connect to the same sql server. In this case it is a "regular" web site. I have it set up to use the same connection string as the web services site ( I can't think of any reason why it wouldn't be the same), however when I try to open the connection ( when I call mySqlConnection.Open(); ), I get get this error:
"SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified"
I am stumped as to why code in one virtual folder has no problem, while the other does. Both virtual and physical folders are on the same machine, and the Sql Server Express is installed on that machine.
The server is a MS Windows Server 2003 machine.
More details as requested.
Thanks,
Kirk

Getting error 1326.
I'm running SQL Express on Server 2003 SP1 (workstation - although, I did dcpromo promote and demote prior to installing SQL Express).
I'm trying to connect from SQL Studio Express on Vista.
TCP and Named Pipes are selected in Surface Area Config; sp_config remote, access..., 1 was run (per KB); ports 1433 & 1434 are open (I think 435 also was opened when I ran the KB instructions); Mixed mode is selected, user is set for SQL Auth, password is correct; all permissions are granted.
I found an article online which stated that mixed versions of MDAC can lead to the problem. The server has 2.82.1830 and the client has 6.0.5600.16834. Could this be the problem? If so, how to solve?
Thanks, John

Hi,
I have installed SQL Server 2005 express edition on Windows 2003 Server, but i am unable to make a connection using
sqlcmd -S <servnameinstancename> -U <loginID> -P <pwd> -d <dbname>
but i am able to make the connection using
sqlcmd -S <servnameinstancename>,<portnumber> -U <loginID> -P <pwd> -d <dbname>
What could be the possible reason for this and how can i configure sql
server 2005 express edition to make connections without specifying any
portnumber in the connection string. Both the sqlserver database
service and browser services are running.

I am having trouble to use SSMSE to remotely connect SQL Express server using IPs other than the base IP of the machine.
Machine settings:
(1) Has multiple IP configured. Those IP are accessible remotely
(2) Firewall is not on.
SQL Express server configuration:
(1) TCP/IP and named pipe are on
Browser service state:
(1) running
(2) listening at 0.0.0.0:1434 (UDP)
SSMSE connection results:
(1) with <baseIP><instance>, connects OK
(2) with <otherIP><instance>, connection failed.
Both connections use exactly the same authentication information.
Testing results using telnet:
(1) telnet <baseIP> 1434, OK
(2) telnet <otherIP> 1434, OK
Does SSMSE actually only listen on the base IP even it shows to listen on all the IPs?

Cannot someone please help me with following problem. I am trying to create a program to update a sql datbase from.NET 2003. I am doing this by using SQL Server Express 5. The problem is, is that when I run the program and click the button to view the table in SQL Express 5 I keep getting an 'System.NullReferenceException' and the table is not shown. When I look at the debug details it says that 'object reference not set to an instance of an object'.
Am not sure where am goin wrong as the connection is opened to the local server in SQL Express and I have created a connection object and initialised it to the address fo the datatable in SQL.
Please find below the code I am working on which shows the connection string in question and the table being called in button 6 which causes the exception.
Any help would be greatly appreciated....thanks

Hello
I am able to connect to the server and most of the time I can't connect.
It is important to be able to connect so I can manage my mdf - database.
To test ... I disable the firework but I still can't connect 90% of the time.
Thank you in advance.

Hi,
I had some issues on my server and had to uninstall .Net Framework 2.0, SQL Server 2005 Express, and SQL Express Toolkit. I installed SQL Server 2005 Express and it seemed to be ok.
Then my problems all started when I tried to install SQL Express Toolkit because I needed to install DTS Wizard again, and it errors out and wouldn't let me install it. So I uninstalled everything that's listed above again.
I then tried to install SQL Server 2005 Express again, and on the second from last screen, while its listing all the components and configuring them, I get the following error as it's configuring the last component... which was the SQL Server Database Services.
TITLE: Microsoft SQL Server 2005 Setup
-----------------------------------------------------------
The SQL Server service failed to start. For more information, see the SQL Server Books Online topics, "How to: View SQL Server 2005 Setup Log Files" and "Starting SQL Server Manually."
I tried to re-install the SQL Server Express another 7 times wth no luck.
If anyone can point me in the right direction I'd really appreciate it.
Thanks,
Bill

I've never used SQL Server before. I installed VB 2005 Express (I've been working with VB since I was 16), and SQL Server 2005 Express.
I installed the server with all the default settings and created a small database to handle customer information (a remake of some Access and Oracle databases I've made before).
I'm told, however, each time I try to connect to the database via VB, that SQL Server isn't accepting remote connections...
Remote? It's on a local computer. So is VB...what is going on here? Is there a setting I've missed?

Within SQL Express 2005 running on Windows server 2003 using asp.net as the interface
This Is the Situation, at first i recieved this error
"
Previously we received a €œfailed to generate a user instance of SQL due to a Failure in Starting the process for the user instance. The connection will be closed€?
I looked up this error and it seams to be a flaw/bug in sql server express the error occurs because of the use of remote login on the windows 2003 server.
The solution to this was to delete an sql server directory that resides here
C:Documents and SettingsUSERNAMELocal SettingsApplication DataMicrosoftMicrosoft SQL Server DataSQLEXPRESS.
This indeed solved the failed to generate a user instance once the server was re-started however now I get a responce within the asp.net pages (which will have been built into those pages)
Your login attempt was not successful. Please try again.
now i have checked the simple errors caps lock etc and tried to log on to the SQL pages directly on the server with exactly the same result. the system was built by somone else and has not been modified "intentionally" just recently i added a few extra databases to the same server location, could this have caused the problem. to my knowlage (e.g i cant recall changing any settings)
there are one or two extenuation circumstances just recently the whole file directory was transfered from one HDD to another and then back to it's original position now i dont think this altered data but possibly there is some inbuilt security or something, i would most sincearly appreciate any questions or answers about this possibly things i havent mentioned that you need to know, just let me know i will get back to you
thanks in advance

Everything was working fine. I have been able to connect using windows authentication. Then, I went into the ODBC manager to add a data source and it failed to connect so I went back into the Server management studio to modify users. After doing this I now get an error when I try to conenct the management studio to the SQL server.
I wasn't modifying the login for my windows account that I normally use, I was modifying a different one, however I now get the message "An error has occured while establishing a connection to the SQL server. This kind of problem can ocure because the default behavior of the server does not support all connection methods" blah blah.
Does anyone know how I can attach to the server? Or, do I need to somehow remove the server and create a new one? How would I do that?
Thanks in advance for any input.

I've seen the following error posted when people try to connect to their server via their applications but didn't see anyone having problems when trying to connect with SQL Server Management Studio Express. Am I missing something here? This is the error:<<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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)(Microsoft SQL Server, Error: 2)>>The server is not remote so I don't see why I need to enable remote connection. I am also using the default connection settings.

On my home machine without permanent network connections enabled, I cannot get the Management Studio connect to the database server. Always get this error:
Cannot connect ot MPLIAMSQLEXPRESS
Additional Information:
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, erro: 26 - Error Locating Server/Instance Specified)(Microsoft SQL Server)
I have used the SQL Surface Area Configuration Tool to reset the defaults to allow remote connections, stopped and restarted the server, but still get the same message.
Please help.

Hi,
I have VS Pro 2005 and SQL Server Express 2005 installed on an XP Pro machine. When using VS 2005, in the 'Server Explorer' window I can see and attach to two SQL Server databases that I have set-up. But if I attempt to access the same databases from withn the 'Solution Explorer' window I get the following dialog box message,
"
Required Component Missing (Dialog box heading)
Connections to SQL Server Files (*.mdf) require SQL Server Express to function properly. Please verify the installation of the component or download from the URL: http://go.microsoft.com/fwlink/?LinkId=49251
"
I have uninstalled and then reinstalled both VS 2005 and SQL Server Express twice but it has helped.
I don't understand why I'm getting this error because all of the server configuration tools and connection utilities seem to work fine but VS say's that SQL Server Express is not installed.
Thanks,
CLN
P.S.
I had another application that required MSDE 2000A to be installed. When I removed the other application I also removed MSDE 2000A and that's when the problem began.

Problem: I upgraded a SQL Server Express instance to SQL Server Enterprise, but I'm unable to connect to the SQL server from any remote machine. Only local connections work -- and I've verified that Remote Connections are allowed in the SQL Surface Confg. utility.
Scenario: Server1 has an SQL Enterprise edition installed as a default installation. SharePoint Server 2007 was installed later, and during that install a SQL Express edition instance was installed which is part of the standard SharePoint install. That Express instance contains all the SharePoint content databases.
So Server1 has SQL instances:
Server1 <default install running Enterprise>
Server1OFFICESERVER <previously running SQL Express, now upgraded to Enterprise>
After upgrading Server1OFFICESERVER to Enterprise, everything seemed to work fine (i.e. SharePoint works fine). However when I try to connect remotely to Server1OFFICESERVER I can't. I've verified through the SQL Surface configuration tool that remote connections are allowed. I've rebooted the server as well. I've tried connecting remotely using various PCs and various applications (e.g. SQL Server Mgmt Studio, Visual Studio, etc.).
Any other ideas to try?

I have installed that free express edition of SQL server 2005 and when i am trying to connect to server from my C#.net application i am not able to do it and when i am trying to degug it gives me the error that is the user is not SQL thrusted user. I am able to connect directly thru SQL server using this userid and password but not thru VWD 2005 Express application.
I have read online that so many people are having that problem. so is it the problem of swl server Express edition or do i have to make some setting to connect to the application.
Please please please please someone guide me . I am stuck here in the beginning only. I would really appreciate it.

using System.Data.SqlClient;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
}
}
protected void Submit_Click(object sender, EventArgs e)
{
String querry;
SqlDataReader dbread;
try
{
SqlConnection conn = new SqlConnection(ConfigurationSettings.AppSettings["Conn1"]);
SqlCommand comm = new SqlCommand();
conn.Open();
querry = " Select password from login where userId='" + TxtUser.Text + "'";
comm.CommandText = querry;
comm.Connection = conn;
dbread = comm.ExecuteReader();
dbread = null;
if (dbread.HasRows)
{
while (dbread.Read())
{
if (dbread["password"].ToString() == Txtpwd.Text)
{
Response.Redirect("home.aspx");
}
}
Response.Write("Your Password Doesn't Match");

When I start Management Studio I get the following message and a suggestion to change a setting:
(I can choose to continue and the system databases appear, but the DB I created does not.)
"Unhandled exception has occurred in a component in your application. Cannot create a stable subkey under a volitile parent key."
************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
Any assistance is appreciated.

I'm having a problem connecting with a Java application but I CAN connect using my .Net application - the user name and password are the same for both (using the same database on SQL Server Express 2005).
The error I get is: "com.microsoft.sqlserver.jdbc.SQLServerException: Cannot open database "CORNERS" requested by the login. The login failed." An interesing note - I get the same message if the database is not running.
SQL Server Express 2005 is installed in mixed mode.
Here is my connection string in the .Net appplication: <add key="connectString" value="Server=(local);UID=sa;PWD=myPasswd;Database=CORNERS" />.
These are my values in my Java app web.xml -
<init-param>
<param-name>DBDriver</param-name>
<param-value>com.microsoft.sqlserver.jdbc.SQLServerDriver</param-value>
</init-param>
<init-param>
<param-name>DBURL</param-name> <param-value>jdbc:sqlserver://localhostsqlexpress:1055;databaseName=CORNERS</param-value>
</init-param>
<init-param>
<param-name>DBUser</param-name>
<param-value>sa</param-value>
</init-param>
<init-param>
<param-name>DBPwd</param-name>
<param-value>myPasswd</param-value>
</init-param>.
And yes, the port is 1055 - I checked to find it.
I am using Microsoft SQL Server 2005 JDBC Driver 1.0 (sqljdbc_1.0.809.102).
Does anyone have any idea what is wrong so that the login fails in the Java application but works in the .Net application?

So I download the Visual Web Developer Express version, and SQL Server 2005 Express along with it. Installed both of them, along with the new Atlas component, and headed over to www.asp.net to start some of the tutorials. I choose one of the Atlas how-tos, and the first thing it has me do is make a new SQL DB from the web developer.
I attempt to do so and get the following error message:
An error occurred while processing the local data file: Key not valid for use in specified state.
A database_log.ldf file is created beneath the db icon, but any attempt to open it results in an error.
Under the Database Explorer window, the usernamesqlexpress.pubs.dbo is marked as not working, and when I attempt to refresh it, I get an error message saying that the requested operation was stopped because a System.Exception was thrown. Looking in the Sql Config Manager, I notice that the SQL Server is running, but not the browser.
Any help is appreciated.

I logged on to my SQL Server Express this morning and received the following error:
Cannot connect to MICHELLEWSQLEXPRESS.
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) (Microsoft SQL Server, Error: -1)
What is interesting is that its on a local computer. I followed one recommendation to enable the pipes and tcp but that didn't work either. How do I change the default settings to allow remote connections (on a local computer) when I can't log into the server?
