Can't Connect To SQL Express 2005
Apr 14, 2006
I have a web app running on a laptop (for demo purposes) with the following connect string:
"datasource=<machine name>SQLExpress;initial catalog=BlueTarp;User ID=sa;Password=xxx"
I can connect to this instance using both oSQL or sqlcmd and can select from the tables within BlueTarp, but my web app won't connect, and I can't figure out why!!
When I installed SQL Express, I used a named instance, called "SQLExpress".
I'm using mixed mode authentication.
One strange thing is that I can connect to either SQLExpress or MSSQLSERVER instances, but they appear to be the same instance -- I can use bluetarp in both.
when I use SQLExpress for instance name in web.config I get "SQL Server does not exist or access denied"
when I use MSSQLServer for instance name in web.config I get "Invalid connection"
And in fiddling with the web.config, I somehow did something to get a machine.config error, something like "machine.config couldn't be loaded because of an unloaded appdomain".
It's driving me nuts because I've spent a good 40 hours on this stupid problem, throwing the whole margin down the toilet.
Does anyone have any ideas?
Thank you,
Aarron

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?

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.

Hey all! I am new in this form and also new with the SQL serve. 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.
the code that i wrote is here:----
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");
}
else
{
Response.Write("Your User Name Is Wrong");
}
conn.Close();
}

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.

I've used Sql Server 2000 and Visual Studio 2003 for a few years. I've started a new position and they have access to Sql Server 2005 Standard and Visual Basic 2005 Express which I'd like to use for a new project. So I installed Sql Server 2005 and then VB 2005 Express on my workstation. I didn't choose the Sql Server option for VB Express because I already had Sql Server 2005 Standard installed with a simple database created. I created a simple vb project that justs connects to the database but I get the following error.
Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0000, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I looked at permissions in the database and it looks ok. I'm the db owner and I'm using Windows Auth. My connection string is
"Data Source=MySystem;initial catalog=AdventureWorks;integrated security=true;"
I thought I'd look at the starter kit to get some ideas about what the problem is, but when I started the movie starter kit project, it was upset that I didn't have Sql Server 2005 EXPRESS installed. Yea, but I do have Sql Server 2005 Standard installed.
Any help will be greatly appreciated. Thanks.

Hallo,
i developed a little web-application.
I'm using a SQL 2005 Express edition db but i cannot connect.
i tried the connection strings from connectionstrings.com but unfortunately they dont list connectionstrings for SQL Express 2005.
Thats the one i guess it should work with:
Provider=SQLOLEDB;Data Source=SQLServerNameSQLEXPRESS;Initial Catalog=Lizenzportal;Integrated Security=true
I always receive following error:
No error information available: DB_E_ERRORSOCCURRED(0x80040E21)
Hope you can help me with this issue.

Hi all,
I'm new to this forum and haven't worked with SQL Server for a couple of years. Now it seems I'm getting back into it. I have SQL Express and SQL 2005 installed on an XP sp2 machine with IIS 5.1. I have a C#/ASP.NET web app in Visual Studio 2005 that keeps getting an error on attempting to connect (SqlConnection object). It's a generic error saying a probable cause is SQL Express default setup not allowing remote connections. Remote connections are turned on for both TCP and UDP. I can connect from within a small C# windows application using the same uid and pwd, so I suspect it's something related to IIS talking to SQLExpress. I would appreciate any help on other things to check. I am also fairly new to using IIS in the development environment.
Thanks

I have installed MS Visual Web Developer 2005 Express Edition on my Notebook (WinXP Pro SP2). And it's working fine. Then I tried installed SQL Server 2005 Express Edition SP1. There is no error during installation and it seems to be working as I can see the SQL Server (MSSQLServer) service is running. As SQL server configulation manager., the protocal shared memory , named Pipes and TCP/IP are enabled.
But when I want to add connection using VWD 2005 by pointing to datasource (MS SQL Server database file and selecing file from .mdf file from SQL sample database file. Then test connection, I got a error that
"An error has occurred while establishing a conneciton to the server. when connecting to SQL server 2005, this failure may be casued the the fact that under the default settings SQL server does not allow remote connections. (provider: SQL Interfaces, error: 26- Error locating server/instance specified)
Can you please advise what the missing part of my configulation ?

Hi All:
I'm new to using sql express 2005 as the database, so I apologize if my question is very basic.
I can connect to db through sql mngmt studio, but I don't know how to connect through application code. The authentication mode is windows. I'm having trouble with the provider in the application code.
Can someone please tell me where I can find more detailed information on available providers for sql express?
Thanks for any help, as I'm against a tight deadline.

Hi all,
I try to connect with a java application to a freshly download SQL server express 2005, but I cannot anything I do.
If I try with the following string "10.0.0.82:1433;databaseName=flavio;user=f.palumbo;" I get this message :
java.sql.SQLException: Impossibile eseguire l'accesso per l'utente 'f.palumbo'. L'utente non è associato a una connessione SQL Server trusted.
If I try with this string "localhost:1433/flavio" I get this message :

So I'm getting crazy to find out a solution ... can somebody help me?

I completely uninstalled all of the beta Express products I had and reinstalled SQL Server 2005 Express first, which seems to have installed ok. Then I reinstalled Visual C# Express, but still have the same problem.
This is happening on my home pc running Windows XP Home sp2. I successfully got sql working with VC# Express at work on my WinXP Pro system.

All,
I'm a newbie here so forgive me if I have missed something completely obvious.
I have bought a shopping cart script of a well known company (Evolve Merchant 5) and I wish to set it up locally on my development server, I created a virtual directory, set the web application up and get the asp pages to display perfectly. However, in the configuration file (global.asa & web.config) for the application it reguests information to be provided: <add key="DBName" value="Database name" />
<add key="DBServer" value="IP address of server" />
<add key="DBUserName" value="User name" />
<add key="DBPassword" value="password" />
<add key="AltPassword" value="password" />
What I can't determine is what the SQL Server 2005's IP address is? the pages of this application show when I type http://localhost/catalogue into IE, so I presumed the server address would be the IP of localhost, when typed ping localhost into command promt it gives me 127.0.0.1, but when I enter this into the config file and try to load the application it just hangs and then eventually says:
"Microsoft OLE DB Provider for ODBC Drivers (0x80004005)[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied./catalogue/global.asa, line 54"
I have created a new database in SQL Express called: merchant509 and restored the tables to it as the manufactures help files state, I created a new login called shop which uses SQl authentication, so as I can provide a password. So the settings should look like this:
<add key="DBName" value="Database name" />
<add key="DBServer" value="127.0.0.1" />
<add key="DBUserName" value="shop" />
<add key="DBPassword" value="1684" />
<add key="AltPassword" value="1684" />
But it doesn't work, does anyone know what i have done wrong?? the SQL server is runnign on the same computer as I am trying to access it from, it is set to accept all forms of comunication i.e. TCP/IP etc.. in the server configuration manager the IP address part of TCP/IP in protocols shows IP1 as 192.168.2.2 active yes enabled yes, and IP2 as 127.0.0.1 active yes and enables yes, I have tried the 192.168.2.2 and this gives the same errors, this is my registed IP on my home network.
I'm now stumped, I haven't a clue what else I can try, I would be very greatfull if anyone has any ideas.
Regards,
Daniel Coates

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?

I am trying to do the Chapter 1 project of Getting Started with ADO.net 2.0 Step by Step (microsoft press)...
I enter the data source configuration wizard and select database, and press next.
I then press the new connection button, and the Choose data source screen appears.
In the List are only 2 options:
Microsoft Access Database File
Microsoft SQL Server Database File.
The option they want me to choose does not appear in the list.
Microsoft SQL Server sqlclient
I tried following the instructions in this thread [http://forums.microsoft.com/msdn/showpost.aspx?postid=85686&siteid=1] where a user had a similar problem, but had no success.
I have reinstalled C#, reinstalled SQL Server Express 2005 with Advanced Tools, but neither helped.
Any help would be greatly appriciated.

I've installed SQL server 2005 Express and set up a database called StockData. I'm running the following code in a visual C# windows app to test the connection:
System.Data.Sql.SqlDataSourceEnumerator instance = System.Data.Sql.SqlDataSourceEnumerator.Instance;
DataTable tblSource = instance.GetDataSources();
string strSource = tblSource.Rows[0][0].ToString() + "/" + tblSource.Rows[0][1].ToString();
SqlConnection sqlConn = new SqlConnection();
sqlConn.ConnectionString = "Data Source=(local);Initial Catalog=StockData;Integrated Security=true";
sqlConn.Open();
I have verified that the SQLEXPRESS service is up and running. The strSource variable shows the machine and SQLEXPRESS instance name when I step through, so I know that the application is recognizing the service. But when I get to the "sqlConn.Open()" line, I get the following error message:
Message="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)"
Source=".Net SqlClient Data Provider"
ErrorCode=-2146232060
Can anyone tell me what I'm doing wrong here? This is driving me nuts. Thanks.

I know there have been many posts made on this subject; however, despite the resources available, I have not been able to get this to work! I've spent time working on this here and there over the last couple of months only resulting in frustration. I am finally posting to solicit help for my situation to figure out what is wrong with my SQL Server or firewall configuration.
Two machines connected to a router, one wireless, one wired. Both have SQL Server Express and the Management Studio tools installed. From either machine I can connect to its local SQL Server Express instance.
I have enabled Shared Memory, Named Pipes, TCP/IP, and VIA in the SQL Server Configuration Manager. (BTW what is VIA?)
I have added sqlsrvr.exe and sqlbrowser.exe to my Windows Firewall exceptions. I have tried disabling Windows Firewall. One of the machines is configured as DMZ in the router configuration.
Please, someone offer up some brilliant diagnostic steps I am missing to expose what is wrong in my setup and make this work... Thank you!

All --
Please help.
Is it possible to connect to MDF file without having SQL Server 2005 Express installed on the machine?
That is-- can one connect directly to an MDF in the same way and Access MDB file can be used?
If no, then is there any way around this?
If yes, then are there any limitations?
Please advise.
Thank you.
