Problem Connecting To Sql Server 2005 Express Database On Local Computer
Mar 18, 2008
I have a very basic console application whose sole purpose is to query a database on the same local computer. When i run the application, i get the error message below:
Cannot open user default database. Login failed.
Login failed for user 'someDomainSomeUserName'.
Below is my connection string also
myconnection_string = New SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=C:Reporting SystemApp_Datasafetydata.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True").
After some googling, some post pointed to deleting a user folder at :
C:Documents and SettingsmyusernameLocal SettingsApplication DataMicrosoftMicrosoft SQL Server DataSQLEXPRESS
but still deleting that folder and restarting the machine doesn't help and i also have remote connections enabled. Help is really needed.
NOTE: The same application runs on a different computer with XP but fails on the Pc with windows server 2003.

Hi,
I just installed SQL Server for the first time on a windows 2003 OS which is on its on server. Then, I installed the client tools on my local computer. Now how do I connect to the sql server with my client tools? What I wanted to do is from my local computer use the enterprise manager and pull up the databases that are located on the server that contains the sql server.
Thanks a bunch,
Laura ;)

Greetings friends,
Not sure if this is the right place for my question but here goes anyway.
I have an instance of SQL Server 2005 installed on my DEV PC. A colleague of mine wants to access my server from his machine which connected to the same network.
I logged on to SSMS and added him as a new login.
Will he be able to connect to it now or do I have to do more than just that?
Your help would be appreciated.

I am unable to connect to a remote server on Computer A from Computer B, but when I reverse it I am able to connect to a remote server on computer B from computer A. I have SQL Server 2005 Developer Edition on both computers. I am using the using the SQL Management Studio to connect. Both Computers have these settings
Using Surface Area Configuration both have local and remote connections checked. Both computers using tcp/ip only checked.
Using Configuration Manager both the sql server and the sql browser are running. Both computers have tcp/ip protocols enabled.
Under the server properties on both computers, under the Security Tab, I have SQL Server and Windows Authentication Mode checked. Under the Connections tab I have Allow remote connections on this server checked.
I believe I have the Security for both the server and databases done properly giving them both proper Logins and User Roles with the proper permission.
Also went to my window firewall settings and under the Exceptions tab, I added both the sql server.exe and sql browser.exe programs on both computers on my remote network.
But when I connect on Computer B, I get an error message stating:
TITLE: Connect to Server
------------------------------
Cannot connect to 'ServerName'
------------------------------
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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 233)

BUTTONS:
OK

I tried pinging server a and then server b and they both pinged.
Could someone please tell me what could be wrong on my remote computers.

Hey All,
I am having a problem connecting to a database I have with a java app I am creating for my senior project. I am using the latest MS JDBC for connecting to the SQL Server.
Below is the code I am trying to run:
try {
ds.setIntegratedSecurity(true);
ds.setServerName("localhost\SQLEXPRESS");
ds.setDatabaseName("*databasename*");
con =ds.getConnection();
} catch (Exception ex) {
ex.printStackTrace();
}
The ds and con variables are declared and initialized correctly. The error I am getting now is this:
com.microsoft.sqlserver.jdbc.SQLServerException: Cannot open database "*databasename*" requested by the login. The login failed.
Any suggestions on what I could be doing wrong?

I have an ASP.NET application that runs under the development server. Before deploying to my host I wanted to test it under IIS. I set up a virtual directory under IIS, but when I try to open the home page I get an error Unable to open the physical file
"E:CDiskLocalWebSitesDIWSchedulingApp_DataDIWDB.MDF". Operating
system error 5: "5(Access is denied.)".and a code dump showing that the code is breaking at the open connection. A little research on the error indicates that IIS does not have permission to execute the database operation. I can not find any information on how to give IIS this permission in SQL Server 2005 Express. Any guidance would be appreciated.

I want to use SQL Server to query an Access Database with about 40,000 rows of data. If possible, I don't want to upsize the database because others need acess to it in the ACC97 format. Is there a way to use ODBC to connect to the ACC97 database so that I can use the SQL query capability of SQL server to query the database.
I know access allows you to write some SQL queries but I need the power of the SQL server and now it is a matter of curiosity because I've been searching for this answer for about 8 hours.

Hello,
Sorry for my question, I know, that there were several topics about sql 2000 vs SQL 2005, I read all them but unfortunately I haven't got the correct answer. I must install my intranet application that uses asp.net 2.0 and SQL 2005 Express to a Windows 2003 server with SQL 2000. It is possible to install SQL 2005 Express beside the 2000 server? It is very important, because I have no possibility to test and that Win2003 server there are a few programs that use SQL 2000. What will happen with the 2000 databases and their programs if I install the 2005 Express to the server? They will work fine with 2000 and my application will work with 2005?
Or instead it should I configure my application to use 2000 capable connentionstrings?

Hi,
I've been trying to fix this error for two days! and I really need the advice of the experts please!
Computer XP Professional Service Pack2, SQL Server 2005 and Visual Studio 2005 (both Standard Edition)
ConnectionString:
<connectionStrings>
<add name="MyConnectionDB" connectionString="Data Source=(MyServerSqlServer2005);Initial Catalog=MyDB;User ID=sa;Password=PasswordforSA" providerName="System.Data.SqlClient" />
</connectionStrings>
C# code
string myConnectionString = ConfigurationManager.ConnectionStrings["MyConnectionDB"].ConnectionString;
SqlConnection myConnection = new SqlConnection(myConnectionString);
myConnection.Open();
Here I get 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"}
What I checked so far:
ServerName and Instance Name OK!
Database, Username and password OK!
SQL Server 2005 Surface Are Configuration - Remote connections using both TCP/IP and Pipe Names OK!
SQL Configuration Manager - Protocolos Enabled (TCP/IP, Pipes, shared) OK!
SQL Server Browse running and active OK!
Am I missing something? I never had this problem with SQL Server 2000 and Visual Studio 2003.
Thanks in advance for any help or suggestion you can give me.

Hi all,
In the VB 2005 Express, I can get the SqlConnection and ConnectionString of a Database "shcDB" in the Object Explorer of SQL Server Management Studio Express (SSMSE) by the following set of code:
///--CallshcSpAdoNetVB2005.vb--////
Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlTypes
Public Class Form1
Public Sub InsertNewFriend()
Dim connectionString As String = "Data Source=.SQLEXPRESS;Initial Catalog=shcDB;Integrated Security=SSPI;"
Dim connection As SqlConnection = New SqlConnection(connectionString)
Try
connection.Open()
Dim command As SqlCommand = New SqlCommand("sp_insertNewRecord", connection)
command.CommandType = CommandType.StoredProcedure
.......................................
etc.
///////////////////////////////////////////////////////
If the Database "shcDB" and the Stored Procedure "sp_inertNewRecord" are in the Database Explorer of VB 2005 Express, I plan to use "Data Source=local" in the following code statements to get the SqlConnection and ConnectionString:
.........................
........................
Dim connectionString As String = "Data Source=local;Initial Catalog=shcDB;Integrated Security=SSPI;"
Dim connection As SqlConnection = New SqlConnection(connectionString)
Try
connection.Open()
Dim command As SqlCommand = New SqlCommand("sp_insertNewRecord", connection)
command.CommandType = CommandType.StoredProcedure
........................
etc.
Is the "Data Source=local" statement right for this case? If not, what is the right code statement for my case?
Please help and advise.
Thanks,
Scott Chang

Hi All,
I've developed an application that connects to a SQL Server 2005 Express database. I created a DSN to connect to the database through ODBC. Currently, I am testing locally and everything works fine.
I would now like to install my application on another workstation and connect remotely to the database located on my development machine.
The client workstation does not have SQL Server 2005 Express installed on it because I would just like my application to connect remotely by creating the DSN and using ODBC. What I'm missing here are the database drivers. The "SQL Natice Client" is not available on this client workstation. How can I deploy the necessary drivers with my installation file so that I may create the required DSN name using the SQL Native Client driver?
Thanks!

I have been creating applications using SQL Express and uploading them to my hoster. No problems there. Now, I feel I'm ready to the next step and would like to start using my hoster SQL Server. I have created a database in their server, now how do I move my created SQL Express Database to their regular SQL Server? Is there a way to run a tool against my local DB and create a script to run in my hoster? What is the best practise here?
Your help is appreciated.

I am working with one other person on a VS 2005 vb.net web project that accesses SQL Server 2005. Both the computers are connected and my partner can run the application on his computer from his VS 2005 but we are getting an error on our first databind to a gridview on the page we are trying to run the error is below
A connection was successfully established with theserver, but then an error occurred during thepre-login handshake. When connecting to SQL Server2005, this failure may be caused by the fact thatunder the default settings SQL Server does not allowremote connections. (provider: Named Pipes Provider,error: 0 - No process is on the other end of the pipe.)
I check the properties of the SQL Server and the check box is checked that says allow remote access. I am not sure what to do.

Hello!
I run an application with a SQL Server 2005 Express edition.
I read under
Start menu
--> all programs
--> Microsoft SQL Server Express
--> Configuration Tools
--> SQL Server 2005 Surface Area Configuration
--> Surface Area Configuration for Services and Connections
--> Database Engine
--> Remote Connections
That:
"By default, SQL SERver 2005 Express, Evaluation and Developer editions allow local client connetctions only. Enterprise, Standard and Workgroup editions also listens for remote client connections over TCP/IP. Use the options below to change the protocols on which SQL Server listens for incoming client connections. TCP/UP is preferred over named pipes because it requeres fewer ports to be opened across the firewall."
Here I chose the option "Local and remote connections only, using TCP/IP only".
But still, does this mean that other users can't connect to my database since I'm running the Express edition?
If that's the case, could this be changed by using mySQL instead?
Is it hard to transfer a MS SQL Server .mdf database file into a new mySQL database?

Hi all
I am about updating some fields with local date and time using blw API
Quote
Private Declare Sub GetLocalTime Lib "kernel32" (lpSystemTime As SYSTEMTIME)
Public Function LocalDateTime()
Dim MyTime As SYSTEMTIME
GetLocalTime MyTime
Debug.Print "The Local Date is:" & MyTime.wMonth & "-" & MyTime.wDay & "-" & MyTime.wYear
Debug.Print "The Local Time is:" & MyTime.wHour & ":" & MyTime.wMinute & ":" & MyTime.wSecond
End Function
Unquote
This works fine however due to it's not really easy for an administrator to keep checking every times wheter local date and time are correctly updated for each front end users computer i would that to reconsider my function and making it to read local date and time from remote SQL Server. my concern is to help administrator to save time as he should only need to ensure that Server is running with correct time...
thkx for any advise

I had SQL Server Express Edition installed. I then uninstalled both it and Visual C#. I then installed SQL Server 2005 Developer's Edition and reinstalled Visual C# -- both on the same machine. I can connect to SQL Server 2005 using SQL Server Management Studio. However, Visual C# is a different story. When I try to add a new Data Connection, it defaults the data source to .SQLEXPRESS, which is no longer on my machine. I can select .MSSQLSERVER, but when I click on either OK or Test Connection, I time out with an error message -- error 25 - Connection string is not valid. The connection string that is shown at the bottom of the Advanced dialog box is -- Data Source=.MSSQLSERVER;AttachDbFilename=E:InventoryDataInventory_Data.MDF;Integrated Security=True;Connect Timeout=30;User Instance=True

I am having major issues connecting to SQL Server 2005 Express from Visual Basic 2005 Express, which I have tried on multiple PCs but to no avail. Can somebody please explain to me what I'm doing wrong?
1) I install SQL Server 2005 Express and Visual Basic 2005 Express (With .NET framework and SQL native client of course)
2) I open SQL Server using Management Studio and going in with windows authentication. It automatically sets the log on name to computernameSQLEXPRESS.
3) I create a new database called Test and add one table to it
4) I go into Visual Basic 2005 and create a new project.
5) I go to the projects application settings (Properties - Settings).
6) I set up a new connection string, choosing SQL server as the conection type and then on the Connection Properties window it asks me to select the mdf file for the database. I choose the file Test.mdf from the directory C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData
7) I click on Test Connection.
When I do this on two out of the three home PCs I get the error:
Unable to open the physical file "C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf".Operating system error 32: "32 (error not found)".
An attempt to attach an auto-named database for file C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
The third PC gives me a different error:
Cannot open user default database. Login failed. Login failed for user 'DAVEDavid'.
I get the same errors when I try to use a connection string inside the code directly. Does anyone have a clue as to why these errors are occuring? Do I need to set up security or something else on the database first, or is there another reason? If anyone can please help me get to the bottom of this or provide a web address where I can get the answer (step by step instructions on how to connect) then I would be most grateful.
