Configuration :: Getting Error "Login Failed For User 'IIS APPPOOLASP.NET V4.0'"

Dec 22, 2010

I'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:

System.Data.SqlClient.SqlException was unhandled by user code
Message=Login failed for user 'IIS APPPOOLASP.NET v4.0'.
Source=.Net SqlClient Data Provider

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

[URL]

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.

Configuration :: Getting Error - Cannot Open User Default Database. Login Failed

Feb 10, 2011

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'.

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?

Security :: Impersonation / Getting Error / Login Failed For User 'NT AUTHORITYANONYMOUS LOGON

Aug 16, 2010

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 ?

Configuration :: IIS 6.0 MVC 2 Web Site SQL Server 2005 Login Failed?

Dec 22, 2010

I have an ASP.NET MVC 2 web site that runs okay on my local machine. The first page that comes up uses data from a SQL Server 2005 database that is on a separate machine.

When I deploy the website to an IIS 6.0 web server and try to open the website in a browser on the web server desktop I get the following:

Server Error in '/AutoDoc' Application.

Login failed for user ''. The user is not associated with a trusted SQL Server connection.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: Login failed for user ''. The user is not associated with a trusted SQL Server connection.

Source Error:

Line 28:

Line 29: <% Html.RenderAction("GenreMenu", "DocStore"); %>

Source File: c:InetpubAutoDocAutoDocViewsSharedSite.Master Line:
29

Stack Trace: [SqlException (0x80131904): Login failed for user ''. The user is not associated with a trusted SQL Server connection.]
There are so many ways to approach this that IM a little lost in the forest. What is the best way to address giving the hosting web server access to the database server? Or should I say give the web site access to the specific database?
