I receive
this error when choosing the data connection in TableAdapter Wizard for me to
reference the ASPNETDB.mdf database.
Failed to open a connection to the database
"The header for file
'C:InetpubwwwrootWebsites4App_DataASPNETDB.MDF is not valid database
file header. The FILE SIZE property is incorrect.
An attempt to attach an auto-named database exists, or
specified file cannot
be opened, or it is located on UNC share."
Check the connection and try again.
I already have the connection at config but the error
persists.
I am receving this error: Failed to open the connection: [Database Vendor Code: 17 ], from .Net 2003/C# to Crystal Report XI with SQL Server 2000 has backend database.
Is there a security permission that has been overlooked?
//Get Table inf from report DB = reportDocument..Database; tables = DB.Tables;
//Looping through all the tables in CR and apply connection info for(int i = 0; i < tables.Count; i++) { table = tables[ i ]; tableLogOnInfo = table.LogOnInfo; tableLogOnInfo.ConnectionInfo = connectionInfo; table.ApplyLogOnInfo(tableLogOnInfo);
I get the below error only when my IDE open. It connects well when it is found closed. [SqlException (0x80131904): Cannot open user default database. Login failed.Login failed for user 'JPASPNET'.] I could solve this by giving the logged in windows user to impersonate under IIS window > WEBSITE > ASP.NET tab > EDIT CONFIG > APPLICATION tab But I wish someone could give me the proper solution. I almost tried all from giving ASPNET user as a administrator to configuring the same in Express management tool. Environment: XP pro, VWD and SQL Express
when i want to open sql it show me error message and when i try again with ctrl+n it works but not complite! i have both .NET2003 and 2005 in my computer under mssql2005 windows2003EP

I am a newbie in sql server and i am creating a web application using VB.NET
I have a button that when i click it will open the database. Heres the code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim sqlConnect As New SqlConnection("integrated security=SSPI;data source=(local)SQLEXPRESS;persist security info=False;initial catalog = CorporateDB;")
sqlConnect.Open()
End Sub
the problem is when i clicked the button an error will show:
Cannot open database "CorporateDB" requested by the login. The login failed. Login failed for user 'TRANSLTRASPNET'. The CorporateDB is the database. And i don't know where did i got this user 'TRANSLTR/ASPNET' My computer name is Transltr but not 'TRANSLTR/ASPNET'.
I tried using this connection string in creating windows application in VS.NET. It works fine. What did i missed here. Please i need your help.
Hi, I'm getting this error ever since I attached my VWD Express database to SQL Server Express. I detached the database after using it and closed SQL Server but as soon as I tried to run my application again in VWD I got... Cannot open user default database. Login failed.Login failed for user 'xxxxxxxASPNET'. I have tried attaching and detaching the database again in SQL Server with the 'Close Connections' check box ticked but still no joy. I have checked out all other posts on this subject but can't seem to find an answer that works for me. Does SQL Server Express do something to users / permissions when attaching databases? It's all way above my head! My connection string is as follows... <add name="DatabaseConnectionString1" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Database.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
Hey,I renamed a database, and it happened to be my default; so I basically screwed myself, because I can't change it through script (doesn't exist or you don't have permissions). What can I do? Thanks.
Hi, I know that there have been numerous posts on this topic, however none of the suggestions seems to resolve my problem. I am running a ASP 2.0 web application locally using SQL server 2005 express, but after using SQL Server Management Studio to browse the database of the application i get the following error everytime i log into the website: Cannot open user default database. Login failed. Login failed for user '<<machine name>>ASPNET' All i had done is attach then detatch the database in SSMS and it seems to have changed the access permissions somehow.I have ensured that the ASPNET user has full permissions (server roles and User mapping) in SSMS and i have granted the ASPNET user full rights to the ASPNETDB.MDF and log file, but i still get the same error. Its really urgent i sort this problem out as soon as possible, so if anyone has tackled this problem before please help. Ideally i don't want to have to reinstall sql server, but if that is the only option and it will definitely fix the problem then i will. Thanks, Jack
I have created an app which use sqlserver exrpress and works fine. I have now craeted a authentication page login.aspx. I have added users successfully to the asp.net configuartion via the web site admin tool. When I go to login using my page I get the Cannot open default database.Login failed. Login failed for user servetaspnet.
I have looked at the asonetdb in sql server management studio and the serverasp net is set up on the database.
Can anyone suggeste what I ma doing wrong or where I might see a work through of the problem. Thanks

I'm using Visual C# 2008 Express to connect to the Northwind database in SQL Server 2005 Express. My Visual C# project which worked yesterday now yields an exception on build.
The error message is:
Cannot open user default database. Login failed. Login failed for user 'Plesva-PCPlesva'.
The connection string is:
Data Source=.SQLEXPRESS;AttachDbFilename="C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataNorthwnd.mdf";Integrated Security=True;Connect Timeout=30;User Instance=True
In SQL Server Management Studio Express, I can see that the default database for this Login is master. In the master database, the user mapped to this Login is 'Plesva-PCPlesva'. The database role membership for this Login in master is 'public'.
Does this have something to do with user instances? I'm not familiar with that topic, but have seen a few posts here and elsewhere that alluded to it. I couldn't make heads or tails of what they were talking about.
Cannot open user default database. Login failed. Login failed for user '[machine name]ASPNET'.I'm working in VS 2005 with a starter kit. I close VS and open an MDF file in SQL Server 2005 Management Studio to modify a table. I attach the file, change a data type, then detach the file. When I go back to VS and try to run the program, I get this error. Everything runs normally before I bring the file into Management Studio. It is not a permissions issue. Does SQL Server put some kind of lock on the file? This must be a fairly common problem. A developer will sometimes want to modify an .mdf file. How does he do that and then run his program? Thank you for any suggestions I can try.
I have installed SQL Server 2005 Express edition and when i try to run the web site as http://127.0.0.1/SiteName/Login.aspx. I am using default SQL Provider.

I have a problem to connect to SQL2005 Express Database with VC++ as regular user, not window system administrator.(If i login as window system admin, everything's working fine.)
A. I tried to use SQL2005 Express Server authentication, the error msg is: Code= 80004005 €œunspecified error€? Cannot open database ***, login failed.
1. I am using Server authentication with username and password. 2. Gave all the permission of Program FilesMicrosoft SQL ServerMSSQL.1 and Program FilesMicrosoft SQL ServerMSSQL.2 to this regular window user. 3. Connection String is: Provider=SQLNCLI;Initial Catalog=***; User ID=***;Password=***;Data Source=***;Persist Security Info=False;Integrated Security=SSPI;
B. I tried to use Window authentication by adding User Instance, but the error is: Code= 80004005 €œunspecified error€? MS Native Client Description = Invalid connection string attribute.
Connection String is: Provider=SQLNCLI;Initial Catalog=***; Data Source=***;Persist Security Info=False;User Instance=True;Integrated Security=SSPI;AttachDBFileName=directory***.mdf;
I got this application system having SQLExpress as database (ABCSystem.mdf). I'm connecting to the database thru connection string specifying database path in App.config.
At the same time, I got two paths for the mdf files. The first one is the path for my database project while the second one is the path to conduct testing. (This means that I got identical ABCSystem.mdf in two paths)
In my development machine, I can run my application where database path is testing path (number 2).
When I tried to copy the ABCSystem.mdf and ABCSystem_log.LDF and my application program files to another PC to test, I got the subject error message. (note that I copy program files under directory "C:Program FilesCompany ABC LimitedABCSystem" and mdf files under "C:Program FilesCompany ABC LimitedABCSystemDatabase")
I try to edit path from database testing path to database project path in app.config, run the application, and notice that it is running OK.
What seems to cause the problem? Coz I need the database in the testing path which is "C:Program FilesCompany ABC LimitedABCSystemDatabase" AND NOT "C:Program FilesCompany ABCABCDatabaseProject".
Hi when i try and open a database in sql server management studio i get the error "Cannot open user default database. Login failed. Login failed for user 'DOMAINUser'. (.Net SqlClient Data Provider)", what can i do to rectify this, i have googled around and still havent found no answers.
I work with Microsoft visual studio 2005. i get data from a table by ADO.NET :
SqlConnection sqlConn = new SqlConnection(strConnectionString); sqlConn.Open(); .....
it works fine.
but when i open the SQL Server 2005 express edition and connect to the server (inside the same computer) to check something and then get back to the VS and run the code again ,the Open() function fails with the exception :
{"Cannot open user default database. Login failed. Login failed for user 'DOMAIN\asaf_a'."
disconnecting the server doesn't help and even closing the SQL Server 2005 application doesn't help. Only restarting the computer enables the Open() command to work again.
I am getting the above error when I try to create Notificatioin services new Instance.
Additional Information is
Failed to connect to server ABC(Microsoft.SqlServer.ConnectionInfo)
An error occured while establishing connection to the server.When connecting to SQL Server 2005, this failure may be caused by the fact that under default settings SQL Server deoes not allow remote connections.(Provider : Named Pipes Provider, error 40 -could not open connection to SQL Server)(Microsoft SQL Server error: 53)
Please help me I am new to SQL Server 2005.I can't able to proceed.
hi, so i have a new box and I'm trying to get my websites and SQL Server 2005 Standard Edition working on it, but the pages give me the following error when I try to load them: "Cannot Open Database "XXXX" requested by login. The login failed. Login failed for user 'xxx'" Everything seems exactly the same settings and user-wise from my old box to my new one, but nevertheless everything I've tried gives me the same error. I've tried creating new users in SQL Server and giving them appropriate permissions to my database. I've even tried just using the built in 'sa' account. Nothing seems to change the error, except when I give it the incorrect password then it just says 'login failed' This leads me to believe that i'm successfully logging into the SQL Server, but it doesn't want to give me access to the database I'm requesting access too. But "apparently" the account i'm using should have access to the database. If nothing else the 'sa' account should, but that didn't work either. I'm stumped. Any ideas?
Hey Microsoft: this affects development that will eventually sell a lot of seats on SharePoint Server 2007. If you guys and gals can't straighten out this mess, you can't expect custom solutions with custom web parts. So pay attention for your own good. Yes, SPS 2007 is what this is all about. I've created simpe web parts and deployed them, same VS 2005, but I need local development and debugging for more complex stuff. I'm really disappointed that you have no solution for this problem.
I've seen other posts on this, but the result seems to be the same: if you fix it, it's by accident, not by design.
1. I created a blank ASP.NET web site
2. I added a web part manager
3. I added a web part zone
I get the error described above. I have no idea why SQL Server settings are so screwed up.
I've tried all the stuff in the other posts - security settings, command line installation, etc. None of those worked.
The default template(s) don't copy anything into App_Data, nor create an empty folder. I don't know why that is. I have other web sites working just fine, but they use remote SQL databases, or local ones I created, and didn't need profile management (no forms authentication, no web parts, no web zones).
I've also started out with a local database, using SQL Authentication, later moving it to a remote server, and never had any problems. The SQL Server developer edition and Express seem to work just fine. I can also debug stored procs when the .mdf is in App_Data. So the problem isn't one of connectivity.
What would cause the default screw-up? This would seem to point from all directions to a problem with Visual Studio (2005)? The installation is defalt - perhaps some extras included (copy local), but nothing unusual. AJAX for ASP.net is installed, but not used in the above "default web site" trial. Likewise Syncfusion's tools, which work fine on other developer workstations at this same location, all of which are from the same image (purchased at the same time & imaged). That web parts work on other boxes, running all the same management tools (anti-virus, remote sys admin/sms etc.) makes none of those suspect.
I think Microsoft needs to have a clean problem solution and publish it. SP1 certainly doesn't fix it. What's worse is the stupid, lame error message. "I can't open the default database". Well, what did you try? What do you think the default is? What settings are you using? Why is there no debugging information other than the usual worthless trace information showing it's all deep within the ProviderBase and SqlClient namespace code? How is that supposed to be helpful?
If anyone has anything solid, not guesses, I'd like to know.
I am very new to VB.Net but my goal is to build a web app that ineracts with an Access database. This is a very small scale app so I am not interested in using SQL server. I created my Access database and the udl file for connection information.
I created a class that opens a connection to the database when the webpage loads.
I get the following error though,
System.Data.OleDb.OleDbException was unhandled by user code ErrorCode=-2147467259 Message="The Microsoft Jet database engine cannot open the file 'C:InetpubwwwrootTest1RaceData.mdb'.

The database is not open so I know it is a matter of security. I have configured IIS to use an admin account and the Access db does not have security turned on. In the UDL file I have selected read/write access and the test connection works.
Can anyone help me narrow down the root of this error,
<add name ="ASPNETDBConnectionString1" connectionString ="Data Source= .SQLEXPRESS; Integrated Security = True; DataBase = ASPNETDB.MDF; User ID = MyWindowsUserName; Password = MyWindowsPassword; User Instance = False; Connect Timeout = 30" providerName ="System.Data.SqlClient"/>
I tried to research on the internet and i got a solution on changing the permissions for this database to enable user SystemName/ASPNET, but iam not able to access this ASPNETDB.MDF from SqlServer and if i go to server explorer in vs2005, i dint know where to chage the permissions.
Database Connection - Don't have permission to open file
I'm trying to establish a connection to a database file (c: empMine.mdf) through visual studio c# express 2005 edition. I'm using the database explorer/add connection wizard. On the add connection dialog window when i browse and select the db file to connect to i'm getting the message "You don't have permission to open this file. Contact the file owner or an administrator to obtain permission"
I have SQL Server Express 2005 and SQL Server Management Studio Express installed. Within the management studio at the server security level i'm mapped to the db file (Mine.mdf) and have db_owner and public ticked and have also set the default database as Mine At the database security level under usersproperties i have also ticked db_owner. Also when i select properties for the db file itself it's telling me that i'm the owner.
I'm also using vista home premium edition and using windows authentication instead of sql server authentication.
I'm fairly new to all this so there may be something glaringly obvious i've missed!

i'm using the Enterpirse library logger to write logs into a database. When choosing connection string i choose the database i want in the "connection properties" dialog box and push 'Test connection' button. everything goes well.
then i open the SQL Server Management studio express and connect to the databse to check some things, from that point on , when i push the 'Test Connection' button in the Enterprise library i get the error:
"cannot open user default database. Login failed. login failed for user My'server/MyuserName'"
even when i close the sql server manager , it is still stuck - the connection test doesn't work anymore.... it only work when i restart the computer.
I Guys I am trying to create an application that writes data to a SQL database (studio express). The application works fine but as soon as I open the table with the SQL server management studio express the application does not work any more displaying the following message:
€œCannot open user default database. Login failed. Login failed for user€¦€?
If I siwtch off and on the computer the problem disappear till the table will be open with the database management studio express!!!!!
Sir i am trying to connect sql from my LAN to my networked computers but whenever i tried to register it through Enterprise manager i get following "SQL Server registration failed because of the conection failure displayed below.Do you wish to Register anyway? Login failed for user 'SW17/Guest'
where SW17/ is my another computer name... i have checked tcp and named pipes and confirm username for sql authentication too please help me as i being late submit my project
I got an approach like that: 1) Read something from DB - check the value, if true stop if false go on2) Read the second Value (another SQL Statement) - check the value etc. Now I could open the connection at 1) and if I have to go to 2) I leave the connection open and use the same connection at 2). Is it ok to do that? The other scenario would be opening a connection at 1), immediately close it after I read the value and open a new connection at 2). Thanks for the input!
