SQL Server :: Cannot Connect To Database, Login Failed?
Aug 20, 2010
I recently upgraded a WinXP machine that had been running VWD 2005 to a Win7 machine using VS 2010. The application targets .Net 2.0, but since the upgrade, I cannot get VS to connect to my database and this is the first time I've tried working on the site since upgrading, so no changes have been made to any code (with the exception of trying to change my connection string so I can connect). The specific error is:Cannot open database requested in login 'dbName'. Login fails. Login failed for user 'SqlLogin'The sql database is on another machine and I was assigned the login/password; I know the login works because I can connect to it with SQL Server Management Studio. Having read several posts and still having trouble, I tried to do a couple things. First I modified my web.config connection string, which looks like this:
[Code]....
When that did not work, I deleted the connection string from the web config and dragged a sqldatasource control onto a page and tried to use the connection string builder while in design mode. Then the error I got was:The database db1 does not exist or you do not have permission to see it. Would you like to attempt to create it?I'm not sure I understand that there is a problem at all, except that I upgraded the OS/IDE. I'm using IIS 7.5 on my local machine to serve the development site while connecting to the development sql server on the other machine. Since I can't use the IIS aspnet account on the remote sql server and my assigned login is verfied working through sql management studio, what else can I do to get my developement site working again?

I am getting this error when trying to connect a database from another computer in my home network:
System.Data.SqlClient.SqlException : Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.
this database is using windows authentication. sqlserver 2008.
What is the connectionstring that I need to use in order to get the database?

In my website i have used a database file named TRAVEL12.mdf, which is present in APP_DATA folder and some how by default a databse file named aspnetdb.mdf is also present in APP_DATA folder , althogh I have not made it......
Now, my problem is that sometimes when I tries to insert some data at any table(that table is in TRAVEL12.mdf database) error shown that login failed to access the default database aspnetdb.mdf for the user...........
Then I deleted the database aspnetdb.mdf, but now also sometime error shown that login failed to access the default database for the user......
as i mentioned that error occurs sometimes not every time which is also a confusion to me!!!.........
I can't understand why this happening??? I am working with TRAVEL12.mdf and I have used it's connection string in my code as a argument of SqlConnection class, so what is the role of default database here!!!

I am not used to work with SQL Server(usually I just use express). I run it on windows server 2008, iis7.
I have attached the database to my sql server. I made a web site in iis7 but I get this error message.
Cannot open database "Phaeton.mdf" requested by the login. The login failed.
Login failed for user 'NT AUTHORITYNETWORK SERVICE'.
Connectionstring I use
<add key="PhaetonConnectionString" value="Data Source=.;Initial Catalog=Phaeton.mdf;Integrated Security=True"/>

I started a new Sql Server 2008 with mixed authentication Windows and SQL SERVER AUTh... I created a new login account and use it to directly connect in SQL server managment studio BUT... when i create in VS2008 the connectionstring... everytime i try to open the DB connection i take an exception to the login... some screenshots show all the process ;)
LOGIN: admintvmaismais
PASSWORD: ex
Working to connect in SQL SERVER MANAGEMENT...
LOGIN STATUS ON SQL SERVER MANAGEMENTE
Now in VS2008 Web-Config I declare the connectionstring:
<connectionStrings>
<add name="SqlConnectionString" connectionString="Server=JP;Database=tvmaismais;User ID=admintvmaismais;Password=ex;" providerName="System.Data.SqlClient" />
</connectionStrings>
and When i try to open a connection like this:
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["SqlConnectionString"].ConnectionString);
try
{
conn.Open();
...
}
catch (Exception e)
{
retorno = e.Message.ToString();
}
finally
{
if (conn.State == ConnectionState.Open)
conn.Close();
conn.Dispose();
}
I get this exception: Cannot open database "tvmaismais" requested by the login. The login failed. Login failed for user 'admintvmaismais'. What am I missing? What do i need to do, to get this login to work?

I have asp.net application, using LINQ to connecto to SQL Server 2008 R2 databse. My connection string: Data Source=[SqlServerIp];Initial Catalog=[databaseName]User Id=newLogin;Password=newPassword; When I deploy application on my local IIS (which is not the same machine as database server)
it works fine, but when I deploy application on other IIS (the same machine as sqlServer) it throws an exception: System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. how to fix it? Maybe it is due to some bad configuration of IIS?

Here is my connection string:
<add name="yafnet" connectionString="Data Source=localhost;Initial Catalog=Scirra;User Id=Gullanian;Password=12345;" providerName="System.Data.SqlClient" />
And I get:
Exception Details: System.Data.SqlClient.SqlException: Login failed for user 'Gullanian'.
I've created the database 'Scirra'. I've also attempted to add a login, but nothing seems to work. Logging into SQL management via Windows Authentication is the only way I can gain access to my DB's.
Ideally I just want to create a user, and that user having full control of DB. So I can run scripts etc.
Here's a few details:
Microsoft SQL Server Management Studio 10.50.1600.1
Microsoft Data Access Components (MDAC) 6.1.7600.16385
Microsoft MSXML 3.0 6.0
Microsoft Internet Explorer 8.0.7600.16385
Microsoft .NET Framework 2.0.50727.4952
Operating System 6.1.7600
Idk why it says v2 for asp.net, all my application pools are set to 4.0.

I'm using an Oracle database(10g) which contains a stored procedure called Foo. Foo takes 2 datetime as IN parameters and 1 cursor as OUT parameter. I've been trying to make the connection and the query to the database with the OleDbCommand, but since Foo needs a cursor I have no choice but to use a OracleCommand(right?).When I try to connection to the database I get the following error : "OCIenvCreate has failed return code -1". I've gived the correct permissions to ASPNET user for the oci.dll file so that it can read and execute it. Unfortunately, I still get the same error and I'm lost.Here is what cause the error
OracleConnectionStringBuilder conBuilder = new OracleConnectionStringBuilder();
conBuilder.DataSource = dataSrc;
conBuilder.UserID = user;

We have created a windows application which is distributed amongst our clients. The application uses SQL Server 2008 as the back end and each client uses their own database on their own server. The databases are all exactly the same but each clients data is specific only to them.
We would like to offer our clients the ability to log-in to our website which would then login to their own database so that when they are out in the field they can perform similar tasks to what they can do with the windows app.Each of the clients databases has a user table containing their login details, permissions etc.
Our server is running on IIS and has SQL Server 2008 installed but it only contains our data and nothing of the clients.How should we go about this?
What I mean is do we need to make each client have an additional login to our main server which would then hold each clients individual connection strings etc which would then be used to connect to there specific database and then they would need to login again?? Seems like a nightmare for the user.

I'm using Visual Web Dev 2008 Express and created a website. The database is an sql server 2008 db and I have added the ASPNET user login I also have the aspnet db object inmy db. When I run my app I can login using the login page, however when I try to retreive data from the database I get the following:
I tried going to Security | Logins | and seting the NT AUTHORITYNETWORK SERVICE to DB owner, but no luck.
What am I doing wrong here?
Cannot open database "TEST" requested by the login. The login failed.

I use to not get this error while accessing the ASPNETDB database, but unfortunately I don't know what I changed. The error comes up when I try to access a file called Admin.aspx I have in a folder called Admin. I had restrictions set on this folder using the Web Site Administration Tool, but when the error came up I took them all of them off to see what the problem was and I still get the error?? The Admin.aspx file is the only one that gets the error..
My connection string in web.config is:
<add name="WIJLConnectionString1" connectionString="Data Source=localhost;Integrated Security=SSPI; Initial Catalog=ASPNETDB" providerName="System.Data.SqlClient" />
Here is the error:

I was working on a asp.net project earlier but due to some OS problem I had to re-install the OS..so before re-installing the OS I detached my sql database and then attached it back after installation..but I am having a login problem now..the previous servername was XYZ-DB840C74SQLEXPRESS..so this user i.e. XYZ-DB840C74ASPNET is added to the database's permissions..now my new server name is XYZ-8D50FD73SQLEXPRESS..but I am unable to add this user through the permissions wizard..I am getting the following error: Cannot open database "finance" requested by the login. The login failed. Login failed for user 'XYZ-8D50FD73ASPNET'.

I am writing a page for creating a new user for a website. After the user fills out the form and click the "Create User" button, the information provided is supposed to be sent for storage to the database. I have been getting the same error message for a couple of days now and I've ran out of things to try. The message doesn't seem like a complicated issue, in fact it's quite common and found a great deal of information on how to resolve it. However, nothing I've tried works. I'm using VS 2010, and SQL Server Express 2005. The message I get is the following:Cannot open database "[database]" requested by the login. The login failed.Login failed for user "[MACHINE_NAMEUSER]".I have added my current Windows account to the Users folder under the Security folder through Management Studio and granted it all the role memberships. I'm also using Windows authentication. If there's any information I'm not providing to figure out what's the issue, let me know and I'll post it.Stack Trace:
