Login failed for user MCTSERVER01\ASPNET.

Hi,

Hope someone can help me to solve the error message.

I am using Visual Studio 2005 and MS SQL Server 2005. When I tried to run the aspx, I encountered the error listed below.

As the error message states, looks like the user does not have enough permissions. Check under the Database -> Security -> Logins and see what permissions the user has.sql

Login failed for user machinename/ASPNET

Hi all,

I am new to ASP .NET and now I have been messing two days with the connection thing. I use the Visual Studio 2003 provided drag and drop SqlDataAdapter and SqlConnection to connect to the SQL 2000 server, developer edition (configured with the Windows authentication mode), but whenever I tried I always got a "Login failed for user mymachine/ASPNET" error. Can anyone help me with this? I have also tried, as somebody did, adding one line "<identity imperonate="true"/> to the Web.config file, but had the same kind of error. Do I have do make some change to my SQL server?

Thanks a lot!

Yes, to resolve the issue completely, you really need to add the ASPNET account to your SQL login and give proper permissions to it. There are lots of similar posts, for example you can take a look at this post:

Login failed for user computername\ASPNET

Hi all,
I get the error message Login failed for user 'computername\ASPNET'
when trying to log to MSDE 2000 SP 3 with .NET application.
My computer is Windows 2000 + SP4 with latest security patches.
I have tried to set the permissions to the database I am connecting
(mydatabase) with script:
sp_grantlogin 'mycomputer\ASPNET'
go
use mydatabase
go
sp_grantdbaccess 'mycomputer\ASPNET'
go
sp_addrolemember 'db_owner', 'mycomputer\ASPNET'
go
Still the error comes.
Does anybody have ideas what to try next.
PS. Software reinstall has been tried (.NET framework 1.1, MSDE).
Regards
Jarmo
Hi,
Did you logged into your machine using 'mycomputer\ASPNET' ? If not login to
the machine using 'mycomputer\ASPNET' and try
connecting using OSQL and confirm.
Thanks

|||Hi Hari,
Local policy does not allow to log in as aspnet:
"The local policy of this system does not permit you to logon interactively."
It is only permitted to log on as a batch job.

I changed the policy to be able to log in.
When giving the command as mycomputer\aspnet user
osql -E -S mycomputer\myinstance
I get the same error message:
Login failed.
Regards
Jarmo
|||There is no need to log in as ASPNET account
Go to MSDN site and look in SQL SERVER 2000 SDK Documentation (it is valid
for MSDE)
There is explanation how to use ASP .NET applications with SQL Server

|||Hi,
thanks for the answers.
This seems to be a problem only in one computer.
In other machines this is working OK.

Login failed for user COLDFIRE/ASPNET

i have my SQL server in windows integrated security so my connection string doesnt have to have password and uid stuff.
this is my connection string

data source=COLDFIRE;initial catalog=Northwind;integrated security=SSPI;persist security info=True;workstation id=COLDFIRE;packet size=4096

i tried this in windows form project of .net and work fine, i connected easily but when i tried it in asp project i got this error :

Login failed for user COLDFIRE/ASPNET

whats wrong with it?That's because the ASPNet user account, which was created when you installed ASP.Net, is not set up as a user on the SQL Server.

Login failed for user ASPNET

Hello,
I am getting following error when I tried to connect to the database.

Login failed for user 'SHALINI\ASPNET'

I am new to this and don't know how to fix it. I am runningSQL Server Desktop engine 2000. I could connect through Server Explorer window, but not through ADO.NET
Here's my connection string:

sConnectionString = "Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=MyStore;Data Source=SHALINI;Workstation ID=SHALINI"

I have IIS and SQL Server running on the same machine.
Please please help me.
Thanks in Advance

If you are just developing on your local machine, be sure the database has the proper permissions.
Also, you may want to try this conn string...

sql = "Initial Catalog=MyStore;Data Source=localhost;Integrated Security=SSPI;"
But once the database is moved to a production server, you would want to change the string to something like...

sql = "Server=isp.com;Database=MyStore;UID=****;PWD=****;"
But this sounds like a permission problem, one in sql server db and in the folder.
You may also want to check the permissions on you folder where you are developing the app, the one in wwwroot.

Hope this helps,
Zath

Login failed for user <DOMAIN>\<MACHINE>$

Folks,

I have read the posts concerning login failures for the ASPNET user. I have a slightly different problem, as you can see from the title of this post.

My environment is a private domain that has two machines:

1) Windows 2000 server on which SQL Server is running. Let's call it FOO_SERVER.

2) Windows XP Professional on which I am running my IIS and .NET development environment. Let's call it FOO_WORK.

3) Let's call the domain, FOO_DOMAIN.

The user, ASPNET, is not a domain user, but a local user, so I do not know how to establish it as a valid login for SQL Server. But this is beside the point, anyway, as the error I am getting has nothing to do with the ASPNET user. It appears that a different username is being used to access SQL Server.

My connection string is:

"server=FOO_SERVER;database=pubs;Trusted_Connection=yes"

The error I receive is:

"Login failed for user FOO_DOMAIN\FOO_WORK$"

I am using the default settings in machine.config. Specifically <processModel> userName="machine" password="AutoGenerate" </processModel
Thanks in advance for any suggestions.

-JoelAre you using mixed mode on your SQL server? If so, you can get rid of the trusted connection, and have user id=sa;pw=; or whatever you want. Good luck.|||Joel,

To get the trusted connection business to work, you're going to need to create an account with the same username and password on the web box and sql box, or on your domain. ASP.Net will need to be configured in the <processmodel> section to run under this account. Of course, proper SQL permissions will have to be granted to the user as well.

Do you happen to have an <identity impersonate="true" /> line in your web.config file?|||Folks,

Thanks to all.

Two different solutions were found to work.

1) Add to the project's web.config file:

<identity impersonate="true" /
This will be required on a project-by-project basis.

2) Modify machine.config:

CHANGE:
<identity impersonate="false" userName="" password=""/
TO:
<identity impersonate="true" userName="" password=""/
This will be a global change, which can be turned off on a project-by-project basis, if necessary, by adding this to a project's web.config file:

<identity impersonate="false" /
I appreciate the help!

-Joel|||I think I got the same issue: Joel can you confirm if I have to do the same thing. I have been pulling my hair out!

Here is my layout

Server1:Machine name:"MyWeb"
Connected to:CompanyDomain (CorpDom)
Connecting using domain user:cooder.

Windows 2003, IIS6,
1st Nic Connected to domain
2nd Nic with Pirvate IP 192.168.1.1

Server2:Machine name:"db_server"

Windows 2003, SQL 2000
1 Nic card with Private static IP 192.168.1.2
DNS pointing to 192.168.1.1

Connected with crossover cable.

Does anyone have information on how to set this up!
How do you get the trusted connection?

So easy setting it up when the DB is on the same machine as asp.net! Help, help please help!

Login failed for localhost/aspnet - please help, been trying for week to solve

I am really at my wits end. I have been trying for days to find an answer to this, and have tried so many things.

I simply keep getting the error that localhost (Phantomlap in my case)/ASPNET cannot access the DB. This is a synopsis:.
Tools I am using:

V Studio 2005, IIS 5.1, XP Pro SP 2, SqlServer 2005 (using the EXPRESS server).
Configurations:

web.config:

<connectionStrings>
<remove name="localsqlserver"/>
<add name="localsqlserver" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\aspnetdb.mdf;Integrated Security=true;User Instance=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
Website is stored at:
C:Inetpubwwwroot
(within that I have an App_Data folder with following permission):
(I allowed, via security, the ASPNET account read/write access)
SQL Server status:
Phantomlap/aspnet user is added
Phantomlap/aspnet security as just about everything checkmarked

Please note--I am using SQLServer Express--I am not entirely sure I added the ASPNET account correctly--is there a tutorial on how to do this?

Please help,

Kind Regards

The real issue here is that User Instances are just not designed for web applications. Are you running this as a file based web site from within VWD (i.e. F5) or is this an IIS based site in production. If you're in production, you should likely start by changing to a standard connection with your database attached to the parent instance of SQL rather than trying to use the dynamic attach behavior of User Instances.

I've never seen anyone from the VWD team provide good instructions on how to work with applications once a database has been added.

Login Failed

Can anyone explain why each time I want to connect to SQL server, I get this error:
Login Failed "WEBCOMPUTER\ASPNET"?(WEBCOMPUTER is my computer name)Because you are using integrated security, and by default, your ASP.NET pages run under the security context of the ASPNET Windows user. You need to add the ASPNET windows user as a user in SQL Server, or alternately, use SQL Server security and provide a username and password.
