DataSource Controls :: Login Failed For User '(null)'?
Jan 28, 2010
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)'. Reason: Not associated with a trusted SQL Server connection".
Having done some reading including here
http://support.microsoft.com/kb/889615 and here http://forums.asp.net/t/1140981.aspx. I cannot see what I am doing wrong.SQL server authentication is set to mixed I am connecting (or trying to) to a windows user not an SQL server login The user has sufficient privileges in the database.
I am trying to use Windows Authentication in my asp code. I have read / tried all answers on the web but couldnt my page to connect to sql. I m using classic asp.
My conn string looks like :
OCONN.OPEN ("PROVIDER=SQLOLEDB; DATA SOURCE myserver; INITIAL CATALOG=nrth; Integrated Security=SSPI; trusted_Connection=yes")

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 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:
I have login page, users enter their username and password ... I want when users enter their password wrong after 3 time they can't enter password until 24 hours after that they can try it again, How i can do it?
When i Run Web Site using Visual studio i dont get the error.it works fine ...But When i run WebSite by publishing on IIS .i am getting the following error.
ERROR:
Login failed for user 'TEGASYSINDTEGADEV3$'.

I use a dbml for my Data Access Layer to provide the data that i need in my app. When i connect from the server explorer everything seems fine. I choose to use my windows authentication and the connection test shows everything works just fine. When i Build my solution and run it on my IIS it says that i'm using a login that is not working.
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 get the above error when trying to run my .net app as it attempts to connect to a SQL database on another server.
The SQL connection string is using a trusted connection. IIS has anonymous access switched off, and integrated windows authentication switched on.
The user the error relates to is "DOMAINNAMEIISSERVERNAME$"
Do I need to add user "DOMAINNAMEIISSERVERNAME$" as a login on the SQL server machine? I expected my username to be passed around - i.e. if I have access to the SQL server then the application would run fine?
EDIT: Should point out that I know it's authenticating OK from an IIS point of view... if I switch to anonymous access it fails my own security as an "Unknown User"... which is what I'm after
