View 3 RepliesI just installed sql server 2005 to my pc and when i try to log in to the server instance i get an error log in failed for user xxx (error 18456).I browse to the server instance and i keep getting the same error even though i chose windows authentication option during the installation.
I restarted the service for the sql server instance (which is running).The only problem i can think about is a problem with permissions but again there should not be any problem there because i logged in as administrator

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'm carrying out a lot of db updates in succession - bulk inserts, bulk updates, deletetions, and other smaller read/write operations. There can be as many as 80 calls to stored procedures in succession, with a few SqlBulkCopy operations thrown in. It isn't possible to reduce the number of operations further. I'm testing on localhost at the moment.
Intermittently, I'm seeing the error:
"Cannot open database "database_name" requested by the login. The login failed. Login failed for user 'SERVERLogin Name'"
It is not a permissions issue, as the same user is used throughout all operations and the error occurs at different stages each time the routine is run. I'm closing (not disposing) the db connection after each procedure. I've set the CommandTimeout to a more than sufficient period.
Should have mentioned: I'm calling these SPs from a Windows Forms app...
I have created an ASP.Net website and tested it using the default server. I used the integrated membership provider for the users login and everything worked fine.
Now I moved to IIS 7 and nothing works anymore. I disabled the read-only feature but every time I try to either register a new user or add an item to the chart I get this error
Cannot open user default database. Login failed.
Login failed for user 'NT AUTHORITYNETWORK SERVICE'.
I'm running IIS 6.0 on a Windows 2003 server and running an ASP.NET 4 application which connects to an SQL Server 2005 database on another server. I have my Default.aspx page set to Windows authentication with anonymous access disabled.
When I load up the page it asks for a username and password (as expected), I enter my credentials and it comes up with the following error:Login failed for user ''. The user is not associated with a trusted SQL Server connection.
If I add the following to my web.config file: <identity impersonate="true"/> then I get the following error:
Login failed for user 'NT AUTHORITYANONYMOUS LOGON'.
And if I add the <identity impersonate> tag set to true and with my username and password included it connects successfully.
I can't leave this in there as I want each user to connect as themselves, so why is the server not using the credentials that I enter when prompted to connect to the database ?
I'm using this for connection to SQL Server 2005 [Windows authentication]
<add key="ConnectionString" value="Data Source=MALIKsqlexpress;Initial Catalog=gainpeace;Integrated Security=SSPI"></add>
but it generates an error
Cannot open database "gainpeace"
requested by the login. The login
failed. Login failed for user
'MALIKASPNET'.
I've narrowed the problem down to the following:
Receive "Login failed" for user ASPNET error message SQL Server 2005 is db and IIS is web server (both on same computer) Mixed authentication used on SQL Server I have created user ASPLogin with password that is correctly typed int the web.config:
add
name="masterConnectionString"
connectionString="Data
Source=computernameGMOSERVER;Initial Catalog=Portal;Persist Security Info=True;User ID=ASPLogin;Password=password" providerName="System.Data.SqlClient"
/>
I am able to access my webpages that query the database as long as they are not parameterized.However, the parameterized queries (e.g., SELECT * FROM SUPP_DASH_RESULTS WHERE organization_code = @orgcode) are the ones that do not work, and give me the "Login failed" error message
my web-app working well locally, but since i uploaded it and my DB, i keep receiving this Error :
Login failed for user 'XXXXX'.

I checked my Username , Password and its Permissions for thousands time, and everything seems to be alright. I developed the Website by ASP.Net / C# (VS2008) and SQLServer2008 and I guess the problem is with ConnectionString, below you can find my ConnectionString:

I have 3 virtual computers (Windows 2003); domain server, database server(name=SQL2000), application server(name=2003APPSERVER).SQL2000 is hosting Sql Server 2000, in mixed authentication mode 2003APPSERVER is hosting IIS 6 and asp.net 2.0 Both servers are in the same domain - IAW The application pool (for the asp.net application) in IIS is operating under the 'Network Service' identity.I have created a new login to the database - 'IAW2003APPSERVER$' (see -
http://msdn.microsoft.com/en-us/library/ms998320.aspx#paght000015_sqlserver).I have assigned this login as a user in the 'demo' database with the db_owner role.I can connect from my asp.net application using an sql login and credentials (different account [obviously]).But when I use this connection string I get "Login failed for user '(null)'.

When I connect to my SQL Server from a ASP.NET application I get a error like Error to connect user 'IIS [App Pool User]' to SQL Server. It's easy to give permitions to that user, but I want the SQL Server to be logged on with the ASP.NET page User Login and not da Application Pool User. It is. if the user DomainUser1 gets logged in. All the SQL Transactions made by DomainUser1.
View 3 RepliesI've created a data set, which is used by a web service I've created on my Windows 7 Ultimate box. (I'm running VS 2010.) When attempting to run it, I get the following error message:

Now, I've checked for answers to how to handle this, and found the following 2 threads on this website:

If at all possible, I'd rather just use a connection string which I've already specified in my Web.Config file, for the dataset, and associated table adapters.
The problem i have would be im getting - 'System.Data.SqlClient.SqlException: Login failed for user 'discountb1'.' error message. my connection string in ASP was the following
"DRIVER={MySQL ODBC 3.51 Driver}; SERVER=CIServer12; DATABASE=BathroomBitsb1; UID=discountb1;PASSWORD=******; OPTION=3"
now just for my simple asp.net page i'm using the following

i believe i have done everything right, but its obviously not the case.
