Error Connecting To Sql Server 2005 Express
Feb 15, 2006
Just manged to install sql server 2005 express after two days. I have a problem now! When i try to connect to it via my browser (local database), i get the following 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)
I have opened the surface area configuration manager and set the connections to remote and local but it still doesnt work
Any ideas would be great

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.

Hello,
I can connect to amachine using SQL server 2000 using IIS 6.0. However, I am having trouble connecting to my server that has SQL server express using IIS 6.0. I'm using similar setting for both servers. Is there something else i have to do for SQL server express?
I'm not sure why this is the case. Any information that could help resolve this failed connection would be greatly appreciated.
Thank you.

Dear Sir,
We are using VB.NET 2005 (Winform) and the backend SQL Server Express 2005. We would like to connect the Express (.mdf) database from Remote Machine. What type of connection string we have to use?
We tried the following ConnectionString but we got the error:
Provider=SQLNCLI.1;Server=.SQLEXPRESS;AttachDbFileName=S:MLJData.mdf;Database=MLJData;Trusted_Connection=Yes;
Also suggest what are all the prerequisites to run sql server express 2005 database in client machine.
We did installed the following tools in client machine:
1. .NET framework 2.0
2. sqlncli.msi (SQL Server Native Client Setup)
Please provide us the solution for this.
Thanks

Hi,
I am using SQL Express 2005 sp1
When I created a linked Server to the DB2 on iseries ( V4R5) , the SELECT statement fetches me only the first record and the following message appears.
OLE DB provider "MSDASQL" for linked server "DB2TEST" returned message "[IBM][Client Access Express ODBC Driver (32-bit)]Driver not capable.".
Msg 7330, Level 16, State 2, Line 1
Cannot fetch a row from OLE DB provider "MSDASQL" for linked server "DB2TEST".
I am using 'MSDASQL' which refers to the DSN setup on my machine using the ODBC "Client Access Driver 32-bit"
Strangely when I used the same DSN in SQL 2000 within the DTS package, I was able to connect and import data and worked like a charm.
Can anyone advice me were I am going wrong.
Thanks in advance

Hi all,
I am having problems with connecting to a SQL Express server running on server 2003. I can connect with the program concerned from a windows xp client without problems. I cannot however connect from a vista machine using the software. In the logs i see the client trying to logon, wich fails with Login failed for user: 'user'. [client: clientIP] severity 14 state 8. On the vista client i have tried everything from disabling the firewall, windows defender, running the app as admin etc. I can connect using sqlcmd or the management tools with the username the app is using. This is a SQL user, we are not using windows users to connect to the DB.I also ran a app like ethereal to see what is happening packet wise, i see the login failed packet on a windows client, from a XP client everything seems fine and it starts using RPC.
Any help appreciated,
FVader

I've been trying to configure remote connections to my sql server express to no avail.
First here are some constants to clear some things up:
- OS: Windows XP Pro
- SQL Express version: April CTP release
- Windows Firewall: disabled (to avoid any problems there)
- Network type: two computers connected a router.
- Router firewall: Enabled (I may be wrong but the router firewall only blocks external traffic, so I left it on.)
First, I configured my SQL server to allow remote connections in the SQL Surface Area Configuration. (Set it to both TCP/IP and named pipes)
Second, I enabled and configured sql server browser.
Third, I enabled TCP/IP and named pipes in the 'Protocols for SQL Express' option of the SQL Server Configuration Manager.
According to http://blogs.msdn.com/sqlexpress/archive/2005/05/05/415084.aspx
I have done everything I need to (including edit the registry to enable the SQL Server Browser service) and the error I continue to get is:
"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)"
So I tinkered and had no success in messing with anything that would fix it. Although, ***when I browsed for network servers on different machine, the server instance DID show up in the list***. So I find it odd that it can find the instance when browsing, but fails to 'find' it when making a connection.
So I didn't stop there, I decided to try the non-sql server browser method of remotely connecting: specifying the IP.
I went back to the blog of instructions referenced above and re-did the steps, this time specifying a TCP Port for the server instance and then after specifying the port on the remote computer connection string, and attempting to connect, I get this 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: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.) (Microsoft SQL Server, Error: 10060)"
I've done all I know how, read all the possible blogs I can, and nothing's come up. If anyone can shed some light on me, I'd pay you 1 billion pretend dollars. Any help would be appreciated. Thank you!

Hello, I have correctly installed sql express 2005 onto my company server. I can connect to the sql express 2005 fine within sql management studio express. I can also connect to it the within visual studio 2005 server explorer. I have my database (MDF) on our server. I am trying to run my application within my client computer. I have changed the connection string property to connect to the server:
"Data Source=CTSSQLEXPRESS;Initial Catalog=UpdateAttributes;Integrated Security=True"
My program will only work if there is a local copy of MDF database located within my application directory. If I remove the local copy, it errors "No process is on the other end of the pipe" Is it possible to have my application without the local copy of the MDF? I thought the idea is to have the MDF on the server. Then my app would not have the MDF copy!?

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?

In ODBC Data Source Administrator, I add the SQL Server driver, complete a name and select my local SQL Server instance, select Windows NT authentication (the client configuration is set to TCP/IP, dynamically determine port) and on clicking Next, the following errors occur:
Connection failed:
SQLState: '01000'
SQL Server error: 2

Connection failed:
SQLState: '08001'
SQL Server error: 17
[Microsoft][ODBC SQL Server Driver][Shared Memory]SQL Server does not exist or access denied.
I note that in the Help it says: "The SQL Server system administrator must have associated your Microsoft Windows login with a SQL Server login ID".
Is this the problem? If so, where do I make this association?
Thanking you in anticipation.

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.

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.

I have installed Server 2005 Express on a pc running Windows Server 2000 sp4 which I want to use as the server for a network of pcs. However, I am unable to login to SQL Express on this machine from Sql Server Management Studio Express. I am in mixed mode and trying to connect with Server Authentication. I get various error messages none of which seem to point to the problem.
Networked to this pc are several other machines running Xp Professional/Home sp2 and if I install SQL Express on one of these I can log in to SQL Express on that machine without any problem. I can also connect to it via the network from the Win Server 2k machine.
Does anyone know of any issues when installing Server 2005 Express on a pc running Windows Server 2000 sp4.
Any help would be appreciated.
Thanks.
