I have just installed Biztalk 2010 server on my machine.
While configuring the server, in the service credentials, no matter what username password I provide, I get the above error.
I used the username password which I use to log into my machine.
Any thoughts?
If its a domain username, use the domain\userid. If its local then use .\userid

This had been working fine in our prior server Windows 2012. New server is 2019.
IIS Setup:
DefaultAppPool using ApplicationPoolIdentity as its identity.
Anonymous and Windows Authentication enabled.
Both prior and current server hitting same SQL Server.
When we try launching the ASP Page, we get this error:
SqlException (0x80131904): Login failed for user 'DOMAIN\MACHINENAME$'.
In other posts I've read that it could be the connection string Trusted Connection setting that is incorrect, but the connection string is built inside the page code and it's never changed.
We've also read that since ApplicationPoolIdentity uses NT AUTHORITY\NETWORK SERVICE as its user, then we'd need to add that service account to the SQL Server.
Again, it had been fine without it in the prior server. But just to try it, we added it to the User list as DB_OWNER in SQL Server.
But still get same error.
Connecting to the SQL server outside of this scenario is no an issue, we can get to it in SSMS and otherwise.
Any ideas and help appreciated!
Thanks
If you see a failure like this: Login failed for user 'DOMAIN\MACHINENAME$'. It means that a process running as NETWORK SERVICE or LocalSystem accessed a remote resource, authenticated itself as a machine account and was denied authorization. When access to the machine account is denied, the machine account must be granted access. If the server denies login to 'DOMAIN\MACHINE$', then you must grant login permission to 'DOMAIN\MACHINE$' instead of NETWORK SERVICE.
I'm trying to fire a web application from my local pc and it throws the error "Login failed for user DOMAIN\USER" (please note that I didn't type my actual values for the DOMAIN and USER in the above error).
I connect to SQLEXPRESS
Database is added through MSSMS and a new user is added to the DB with the values from connection string.
Changed authentication to SQL Server and Windows Authentication Mode but still the same error.
Changed connection string with Windows login details but still the same error
Are you intending to login using SQL authentication or Windows authentication? It sounds like you are trying to login using SQL authentication (i.e. named SQL User and password), but your connection string is indicating to use windows authentication (something like SSPI=True)
So you need to verify what login method you want to use: Windows or SQL
Then you need to post your connection string
I have a local test environment set up with IIS. I'm using the connection string below to connect with c# in the codebehind of an ASPX page using my windows auth. I am getting the error that [PCNAME]/ASPNET login failed. Why is the user name ASPNET attempting to login when I've specified my connection string to use my login?
user id=[UID];password=[PASS];server=[LOCALSERVER];database=db_specialOps;Trusted_Connection=yes
Trusted authentication uses the credentials of the user that is executing the process. If it is specified as yes, then the username and password in your connection string are ignored.
In this case, the ASPNET user account is the user that is running the process, so this is the account that is being used to connect to SQL Server.
Checking, another SO question addresses this issue.
When using Trusted_Connection=true and SQL Server authentication, will this effect performance?
Remove the Trusted_Connection=yes part of the connection string. It tells the sql client library to connect to the sql server, using the Windows auth, with the current process' Windows identity. In the ASP.NET case that is [PCNAME]/ASPNET. That's why you see that error message.
If you want to use sql auth, just supply username and password as you do - without the Trusted_Connection=yes part.
Connection string for Windows authentication:
connectionString="Server=MyServer;Database=MyDb;Trusted_Connection=Yes"
OR
connectionString="Initial Catalog=MyDb;Data Source=MyServer;Integrated Security=SSPI;"
No user/pass
Connection string for SQL authentication with user/pass
connectionString="Server=MyServer; Database=pubs; User Id=MyUser; password= P#ssw0rd"
providerName="System.Data.SqlClient"

Connect to SQL Server using windows authentication and specific account
Here is my Error:
ERROR [28000] [Microsoft][ODBC SQL
Server Driver][SQL Server]Login failed
for user 'NT AUTHORITY\ANONYMOUS
LOGON'. ERROR [28000] [Microsoft][ODBC
SQL Server Driver][SQL Server]Login
failed for user 'NT
AUTHORITY\ANONYMOUS LOGON'.
Here is my connection string at application start up:
MyConnection = New Odbc.OdbcConnection("DRIVER={SQL Server};SERVER=MySqlServer;Trusted_Connection=True;DATABASE=MyDatabase")
Here is part of Web.Config:
<authentication mode="Windows"/>
<identity impersonate="false"/>
Here is my IIS(7) settings:
Authentication
Anonymous Authentication: Disabled
ASP.NET Impersonation: Disabled
Basic Authentaction: Enabled
Digest Authentication: Disabled
Forms Authentication: Disabled
Windows Authentication: Enabled
Connection Strings
MyDatabaseConnection: Data Source=MySqlServer;Initial Catalog=MyDatabase;Integrated Security=True
LocalSqlServer: data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true
I believe you may have to use ASP.Net Impersonation in this case.

As Zach says, you need to change the credentials of the user accessing the database.
So you either need to turn on impersonation as recommended or you should change the user id and password used by the application pool that is used to run your web site. This MSDN article, while a bit old, still applies and should help you do that.
What user account should be used to connect to the database? Your user account, an account on the SQL server, the IIS app pool account?
By default, if you don't give the connection string a username and password, .NET will use the AppPool's credentials, which as Simen says doesn't have sufficient privileges to the SQL server.
If you want to use the credentials of the user accessing the website (probably a bad idea), you need to use impersonation as Thyamine says, but if you want to use a SQL account that is set up for the database, then you need to put the username and password of that user into the connection string. (http://www.sqlstrings.com/SQL-Server-connection-strings.htm)
if your web application is running without Integrated Security. remove the "Allow Anonymous connections" security option. When authenticated by the web server as ANONYMOUS the request will be executed using an identity does not have sufficient privileges to your SQL Server DB.
Edit: If you are running the web server on a separate machine than the client machine you might want to investigate whether the server actually recognizes the account used on the client machine. If the machines are not part of the same security domain, you might even have to go through the questionable procedure of modifying the server's
Local Policies --> Security Options --> Network access: Sharing and security model for local accounts to the setting : Classic - local users authenticate as themselves and creating a user account with the same name and password on the server.
You might also want to investigate http logs on the server
My feeling says it's not posible but anyway I am curious if there is at least a workaround for accomplish this.
Basically I am working at my client site and my machine is not connected to the domain.
What I want to do is running a web application locally under a domain account, and using the webdev server.
The webapp uses the default authentication, windows authentication that is.
I tried using impersonation with domain\user & password but I got the following error
Could not create Windows user token from the credentials specified in the config file. Error from the operating system 'Logon failure: unknown user name or bad password.
I have to mention that the username and the password are correct.
Thanks in advance
Iulian
If you cannot access the domain controller (or your computer does not know what domain controller to use), there is no way finding out if the password is correct or not. What normally Windows does, is asking the DC "does this password match this account" (simply speaking). Now in your scenario, there is no DC. Hence, "unknown username".
