I am facing below error while connecting on premise SQL Server database in Azure Data Factory. I was establish a self hosted integration IR which running fine. Any one help on this please.
Cannot connect to SQL Database: '_&', Database: '', User: '________'. Check the linked service configuration is correct, and make sure the SQL Database firewall allows the integration runtime to access.
Cannot open server '____&' requested by the login. Client with IP address '223.196.174.128' is not allowed to access the server. To enable access, use the Windows Azure Management Portal or run sp_set_firewall_rule on the master database to create a firewall rule for this IP address or address range. It may take up to five minutes for this change to take effect., SqlErrorNumber=40615,Class=14,State=1,
Activity ID: _____________.
Thanks in advance!
Client with IP address '223.196.174.128' is not allowed to access the server.
That's not an error you'll ever get from an On-Prem SQL Server. That error is coming from Azure SQL Database, and it means exactly what it says. Your client IP is not allowed to connect in the Server's Firewall.
We tried to do one poc which meets our upcoming requirement in my personal Laptop. The requirement is migrating the on premise sql database into azure sql database.
The screen shot of error is,
Connection error message and description
Below are steps which we have done.
Step1:
We have created a sql database in azure portal. The server name is like sundar64599.database.windows.net
The Screenshot is here, Sql database in azure poral
Stpe2:
Then We have done the assessments and created the migration project in Data Migration Assistant tool and we deployed it successfully.
Step 3:
Then we created a Database Migration Services and tried to create a migration project.
Here we entered the source server details to connect and it throws the error as mentioned added the screenshot above.
And also we tried the below to resolve this connect issue.
1. In sql server confuguration management,
a. We restarted the sql server and tried to connect. But it fails. The screenshot is Sql server restart
b. Then we had set the TCP port as 1433 and dynamic port as 50313 and tried to connect. But it fails. The Screenshot is, Tcp with dynamic port
c. Then we had set the TCP port as 1433 and dynamic port as empty and tried to connect. But it fails. The screenshot is, Tcp empty dynamic port
2. In Sql database of azure portal, we checked the client ip and added the exact ip and tried. Even it fails. The Screenshot is, Firewall ip settings
Please add your suggestions to resolve this connection issue.
Thanks in advance,

You need to provide the FQDN (Fully Qualified Domain Name) or Public IP of the source server as described here. The way you are providing the source server will work in the local network but not from outside, which is required by the Azure Migration services.
So make sure that your source server is available from the internet. You can have a look at the complete steps here - https://learn.microsoft.com/en-us/azure/dms/tutorial-sql-server-to-azure-sql
Its a bit strange. Until yesterday I was able to connect to all of my SQL Servers. Once I restarted my computer, a new firewall seems to have been unexpectedly added. I tried to sign in to my azure account, but I am still getting the same error.
I have had a similar problem myself in the past, and trying to configure firewall settings through SQL Server Management Studio could not solve it for me. Instead I did this:
Log into Microsoft Azure
Go to your SQL Server that you are having difficulties with
From the menu, select "Firewalls and Virtual Networks"
Select "Add Client IP"
Enter your public IP address.
There is also documentation here
I created an Azure SQL Server. I have set the firewall, added my IP address to the rules. I tried to log in using SQL Server Managment Studio but got the network error every time. I am using the Server Admin Login and password created while creating the SQL server. Are there any more steps required to log into the SQL Server?
Note: I also enabled port 1433 for inbound connections on my PC.
According to the error message, we should check the server name of the database.
We can select the database here, and SQL Server Managment Studio will type the server name automatically:
Another way, we can find the information via azure portal, then type the server name manually:
It seems you are using named pipes to connect to SQL database. What happens if you specify TCP/IP protocol in advanced properties tab?
Thanks Everyone for your inputs. The only issue was, the firewall was blocking the port 1433. After opening it, I could connect to the SQL Server hosted in Azure. The link below mentions the requirement to open the said port. https://learn.microsoft.com/en-us/azure/sql-database/sql-database-develop-direct-route-ports-adonet-v12
I am trying to host a SQL server database, but whenever I try to connect to it I get this error:
The login is from an untrusted domain and cannot be used with Windows
authentication
I am connecting through Matlab using the following command:
conn = database('Clinical_Data','DoyleLab07\Acc','','com.microsoft.sqlserver.jdbc.SQLServerDriver','jdbc:sqlserver://DOYLELAB07\SQLEXPRESS:54287;database=Clinical_Data;integratedSecurity=true;').
Connecting to the database using matlab worked fine as long as I was using matlab on the computer which I was using to host the server. However, when I use another computer and the same Matlab command I get the error I showed above.
When I look under control panel\system. I notice that no domain is listed on my host PC or the PC I am using to connect to the host, but both computers are in the same workgroup. Would I be able to fix my problem by creating a domain and adding the foreign PC and the host to that domain? If so, how can this be accomplished?
Any suggestions will be very much appreciated.
Thank you for reading my post.
Getting rid of Integrated Security=true worked for me.
In order to use Windows Authentication one of two things needs to be true:
You are executing from the same machine as the database server.
You have an Active Directory environment and the user the application is executing under (usually the logged in user) has rights to connect to that database.
If neither of those are true you have to do one of two things:
Establish a Windows Domain Controller, connect all of the relevant machines to that controller, then fix SQL server to use domain accounts; OR,
Change SQL server to use both Windows and SQL Server accounts.
By FAR the easiest way is to change SQL Server to use both Windows and SQL server accounts. Then you just need to create a sql server user on the DB server and change your connection string to do that.
Best case option 1 will take a full day of installation and configuration. Option 2 ought to take about 5 minutes.
If your SQL Server is on one domain controller and you are trying to connect to it from another domain controller then you will get this error when
IntegratedSecurity = true;
This will happen even if you include a valid SQL Server username and password in your connection string as they will automatically be over-written with your windows login and password. Integrated security means simply - use your windows credentials for login verification to SQL Server. So, if you are logged in to a different domain controller then it will fail. In the case where you are on two different domain controllers then you have no choice but to use
IntegratedSecurity = false;
Now, when Integrated security is false SQL Server will use the SQL Server login and password provided in your connection string. For this to work, the SQL Server instance has to have its authentication mode configured to mixed mode, being, SQL Server and Windows Authentication mode.
To verify or change this setting in SQL Server you can open the SQL Server Management Studio and right-click on your server name and then select Properties. On the pop-up that appears select Security and you will see where to alter this setting if you need to.
I've had this same issue when using DNS aliases and hosts files to connect to a machine using a different domain name.
Say you have a SQL server called sql1 on mydomain.com - which is an Active Directory domain - and you also have a DNS zone for mydomain.net, and - for consistency - you set up a DNS alias (CNAME) record for database.mydomain.net --> sql1.mydomain.com
You'll be able to connect to sql1.mydomain.com using Windows integrated security, but won't be able to connect to database.mydomain.net even though it's the same server because the domain name doesn't match your AD domain.
This error message can also occur if the account you are using to access the SQL server is locked out by the domain.
I was facing the issue while connecting to SQL Always On Listener. Disabling the loop back check resolved the issue.
Edit the registry using regedit. (Start –> Run > Regedit )
Navigate to: HKLM\System\CurrentControlSet\Control\LSA
Add a DWORD value called “DisableLoopbackCheck”
Set this value to 1
https://blog.sqlauthority.com/2017/04/18/sql-server-login-failed-login-untrusted-domain-cannot-used-windows-authentication/
Why not use a SQL Server account and pass both the user name and password?
Here is the reason why.
In short, it looks like you have an authentication issue.
The problem with workgroups is there is no common Access Control List like Active Directory (AD). If you are using ODBC or JDBC, the wrong credentials are passed.
Even if you create a local windows account (LWA) on the machine (SE) that has SQL Express installed (SE\LWA), the credentials that will be passed from your client machine (CM) will be CM\LWA.
As mentioned here, you might need to disable the loopback
Loopback check can be removed by adding a registry entry as follows:
Edit the registry using regedit. (Start –> Run > Regedit )
Navigate to: HKLM\System\CurrentControlSet\Control\LSA
Add a DWORD value called “DisableLoopbackCheck” Set this value to 1
If you using windows authentication make sure that password of the user hasn't expired. An expired password can explain this error. This was the problem in my case.
Same Error with Connection String in Visual Studio dev environment
Our development database server was recently given a self-signed certificate so it automatically became untrusted. This resulted in the login error cited above. I added TrustServerCertificate=True to my connection string and it works now.
"Server=TheServerAddress; Database=TheDataBase; User Id=TheUsername; Password=ThePassword; TrustServerCertificate=True"
NOTE: This certificate configuration is not recommended for production environments.
In my case the Aliases within SQL Native Client 11.0 Configuration were pointing to invalid server/IP. Once updated it worked correctly.
To check:
1. Start "SQL Server Configuration Manager"
2. Navigate to "SQL Native Client 11.0 Configuration" and then "Aliases"
3. Ensure "Alias Name" and "Server" match correctly for TCP/IP
Following worked for me to get access from another machine to SQL Server using Windows Authentication. This approach may be useful only in development/test environment. E.g. you need to update password manually once you change it on your working machine.
On machine with SQL Server go to Control Panel and add new Windows User with same username and password as is on your working machine. Then create SQL Server login for this user:
CREATE LOGIN [SQLSERVERHOST\myuser] FROM WINDOWS;
Now you can use this login for Windows Authentication.
If you receive error 'The login is from an untrusted domain', this may mean that you changed password on your working machine and now need to update password on SQL Server machine.
Just adding my suggestion for a resolution, I had a copy of a VM server for developing and testing, I created the database on that with 'sa' having ownership on the db.
I then restored the database onto the live VM server but I was getting the same error mentioned even though the data was still returning correctly. I looked up the 'sa' user mappings and could see it wasn't mapped to the database when I tried to apply the mapping I got a another error "Fix: Cannot use the special principal ‘sa’. Microsoft SQL Server, Error: 15405". so I ran this instead
ALTER AUTHORIZATION ON DATABASE::dbname TO sa
I rechecked the user mappings and it was now assigned to my db and it fixed a lot of access issues for me.
Joining a WORKGROUP then rejoining the domain fixed this issue for me.
I got this error while using Virtual Box VM's. The issue started to happen when I moved the VM files to a new drive location or computer.
Hope this helps the VM folks.
We now use a privileged account management solution that changes our passwords regularly. I ended up receiving this error after my password was changed. Closing and re-opening SSMS with the new password resolved my issue.
I started to get this error when i tried to login to SSMS using 'windows Authentication'. This started to happen after i renamed the Windows SQL server. I tried everything to resolve this error and in my particular case changing the machine names in the 'hosts' file to reflect the name SQL server name change resolved the issue. C:\Windows\System32\Drivers\etc\hosts
I had this problem because we where using a DNS name from an old server, ponting to a new server. Using the newserver\inst1 address, worked. both newserver\inst1 and oldserver\inst1 pointed to the same IP.
Yet another thing to check:We had our nightly QA restore job stop working all of a sudden after another developer remoted into the QA server and tried to start the restore job during the middle of the day, which subsequently failed with the "untrusted domain" message. Somehow the server pointed to be the job's maintenance plan was (changed?) using the ip address, instead of the local machine's name. Upon replacing with the machine name the issue was resolved.
TLDR: Changing the DNS server to the loop back address worked for me.
I am working in VirtualBox and had setup two Windows Server 2016 instances. Server A is configure as a Domain Controller and Server B as an SQL Server. After adding Server B to the domain I cold not connect to with Management Studio from Server A. I was getting the "The login is from an untrusted domain and cannot be used with Windows authentication".
My initial configuration had the server getting its IP from the VirtualBox DHCP server.
I changed this to use static IP and entered the 127.0.0.1 address in the Primary DNS and this worked for me.
Hope this helps someone passing by.
I enabled Trust Server Certificate in the Connection Properties and it worked for me
You might find out that you have more than one connection string, and you forgot to change the other one to Integrated Security to false. It happened to me. This answer might help someone.
I was focusing on the web config and the access rights, after a long hustle i remembered that I have another connection string in one of my classes for the emails, I had to change the connection string on the class to use the web config one.
i removed Integrated Security=true and Trusted_Connection=True both of them , worked for me..
In .net Core also you may get this error if Trusted_Connection=True;
Is set. Sample setting in appsettings.json
ConnectionStrings": {
"DefaultConnection": "Server=serverName; Database=DbName; uid=userId; pwd=password; MultipleActiveResultSets=true"
},
Sometime SSMS hang and close all of sudden ,then you get below error when you reconnect to SSMS
i) The Login is From an Untrusted Domain and Cannot be Used with Windows Authentication
OR
ii) The target principal name is incorrect .Cannot generate SSPI context.
In both cases RESTART YOUR MACHINE.
I also had a similar error but then I realised I just had changed the password for my system which caused this error.
To resolve it , I simply logged out of the current session and logged in again and this time
Please Use This Connection URL It's Work Fine
"Data Source=Your IP Address;Initial Catalog = DatabaseName;User ID =sa;Password =your PassWord;TrustServerCertificate=True"
Example : "Data Source=192.168.150.122;Initial Catalog=StudentDb;User ID=sa; PassWord=123;TrustServerCertificate=True"
If you have two servers on the same domain (eg. APP and DB), you can also use Windows Authentication between the app and MSSQL by setting up local users on both machines that match (same username and password). If you don't have the passwords matched up, it can throw this error.
Following was working for me. hope this helps you
<add name="getconn" connectionString="Data Source=servername;Initial Catalog=DBName;Persist Security Info=True;User ID=sa;Password=***" />
