SQL Server :: Login Failed For User 'SERVERLogin Name?

Mar 28, 2011

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...

Security :: Login Failed For User ' Only With Parameterized Query Using SQL Server Authentication

Nov 29, 2010

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

C# - Sys.WebForms.PageRequestManagerServerErrorException: Login Failed For User?

Sep 20, 2010

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

Security :: Login Failed For User 'ADXXWEB1$'?

Jul 31, 2010

I'm developing an ASP.net 3.5 Intranet Site for a client of mine on my development system. Recently, I copied the solution to my Client's Server across a VPN. I was able to access the home page, but that is all. WHen I attempt to open another page I get the following message. Login failed for user 'ADXXWEB1$'.where AD is the name of the Domain and XXWeb1 is the name of the server.Before a user can access any other page I check the user using a vb.net function. I grab the user from the following lineDim usr1 = HttpContext.Current.Userts Saturday night and my clients are off enjoying the weekend (lucky guys) but I would like to try and do more work. I assume I'm getting this message because the server doesn't recognize me because I'm on the VPN. Is there any way around this?

Configuration :: Login Failed For User 'NT AUTHORITYANONYMOUS LOGON'?

Aug 4, 2010

I'm developing an intranet site in asp.net 3.5 using linq to sql. When I run the site on my development system, it works great. I moved the site and SQL Server database to my CLient's Server for testing.

When I execute the following vb.net code

Dim linq1 = From PageGroup In dbs1.ZZ_PageGroups Where (PageGroup.PageName = pasPageName)

For Each PG In linq1

I get the above error message. I suspect the problem may be authenticating the user in SQL Server. When using Linq to SQL, how/where is the connection string set and how does it know the user?
