Setup And Upgrade :: Windows Authentication Not Working After Password Change?
Apr 29, 2015
This morning I attempted to connect to my local copy of SQL Server (2012) (Win 7) using Windows Authentication. I was unable to do so and per the error log it was due to error 18456 (invalid credentials).
Yesterday I changed my windows password. Is it possible for this to be the cause?
FYI, following is from the error logs:
2015-04-27 10:10:32.98 Backup BACKUP DATABASE successfully processed 0 pages in 0.451 seconds (0.000 MB/sec).2015-04-28 00:00:41.90 spid18s This instance of SQL Server has been using a process ID of 2096 since 4/21/2015 9:08:05 AM (local) 4/21/2015 1:08:05 PM (UTC).

This is an informational message only. No user action is required.
The logs showed the error occurred yesterday (4/28) which is about when I changed my password. The 17:09 log (last one) is when I shut down my computer. Note that I was logged into SQL Server when I changed my Windows password and worked with it several times through out the day.
Also, per the configuration manager SQL Server (MSSQLSERVER) (and all other services) is stopped and I was unable to start it ("The request failed or the service did not respond in a timely fashion).
I have instaled SQL Server2000 in Administrator user login.My OS is Windows Adavance Server2000. It works Fine. If i change my Administrator Password and Login with the new Password then Sql Server dosn't Run.It says Authentication error if i try to run from service. I belive DBA's in this forum can help me out.
We are experiencing authentication/ Kerberos issues after a password for the MSA's has changed. We use MSA for our SQL 2012 and windows 2012 combination Servers. This errors creates issues while backing up and Service Broker connectivity.We had to restart sql services to fix it, but this not seem to be a resolution for me because the next time the password changes on these MSA's we may have to restart sql services.There seems to be a known issue for windows 2008 R2 servers and fix is available and we incorporated it. But the issue we are facing is on windows 2012 Server.
I am trying to access the SQL server using windows authentication but its not working. But others can work on their windows authentication for the same server. Anything needs to be done from my end. Please explain.
When logged onto a server and connecting using windows authentication (either by server name or localhost) I am getting in fine, but when I connect using the IP I get the following error.
I can log in using SQL Server authentication with the IP.
I'm trying to connect to a SQL Server 2005 database engine on a local network server. When I am presented with the Connect to Server dialog box, if I select Windows Authentication from the Authentication drop-down, the User name & Password area is grayed out and unusable. The domain user account I'm authenticated with is visible, but grayed out, and the password field is blank and unusable. I'd like to be able to connect as described in help:
User name
Enter the user name to connect with. This option is only available if you have selected to connect using Windows Authentication.
I can connect with either SQL Server or Windows authentication... but with Windows Authentication I'd love to be able to type a specific user name to select with :-)
We need to use SQL Server Authentication for some reason and would like to enforce Password Policy with 90-day expiration period. I found "Change password" dialogue appears when I first logged in with the new user, but don't know
(1)what happens when the user failed to change the password before it's expired or (2)how a user can change his password in advance of the expiration date with no particular server-level permission.
I have a publisher, distributor and subscribed in transactional replication topology, each on a different MS Windows 2008 server. SQL server version is 2008. I changed the password of the service account used to the the sql server and sql server agent services on all 3 servers. But now replication stopped working (Distributor to publishers shows errors in replication monitor for all publications).
I restarted the services and also tried restarting the servers. I did "update replication passwords" and also used sp_changereplicationserverpasswords to change replication passwords. But it doesn't seem to work.
From [MSrepl_errors], i get the below errors:
The process could not connect to Subscriber 'XXX'.
Cannot generate SSPI context
SQL Server Network Interfaces: The target principal name is incorrect.
I have my SQL 7.0 server set for Mixed security. I see now (finally)the advantages of having windows authentication security for windowsgroups.I do most of my developing in Access Projects which require a login ofsome type. I have been using my SQL login to develop with SQL andthen when I give it to the user, I set the project to use Windowsauthentication. I want to be able to have Windows authentication onmy domain account but the user name for my windows account is the sameas my SQL account and it won't let me change the existing account.Now what happens is after I develop the product I have to have theuser login and go in and change to windows authentication. It won'tlet me do it with my sql account.I fear that if I delete my sql account and create a windowsauthentication account all the views, sps, etc. that I have createdwill still have the reference to the sql login and therefore not work.Do I need to have a generic sql account for developing? One thought Ihad was to create a new domain account so I can create that windowslogin and at least get my most recent projects working like I want to?Hope this makes sense to someone.Thanks in advance for your time.Sherry
I am working on SQL Server 2014 and I want to know, Is it possible to change the location of SQL log file and will it affect to the database if it is possible to change its location?
Unhandled Exception: System.Security.SecruityException: Request failed. at Microsoft.SqlServer.Chainer.Setup.Setup.DebugBreak() at Microsoft.SqlServer.Chainer.Setup.Setup.Main()
Then the Managed SQL Server Installer box pops up with Managed SQL Server Installer has stopped working.
I need to change the authentication mode from 'windows' to mixed, its a 4-node participating in always-on... Will this brake/impact alwayson in any way? I know I have to restart the sql instance.
Hi there,I have installed MS SQL Server 2005 on my machine with windows authentication. But now I want to switch the authentication mode to SQL Authentication. I am unable to switch, I can’t find the proper way to do so here in 2005.Could any one help me in doing this?Thank you,-Ahsan
We're doing upgrades from SQL 2008 R2 to SQL 2014. This is blocked due to RS is installed but not configured. Our desired action is to uninstall RS and proceed with the upgrade. But when setuparp.exe is raised, it does not list all the features on the 'Select Features' page. In fact, it only lists the last 2 shared features (SQ Client Connectivity SDK and Microsoft Sync Framework). However, all items appear to be listed on the 'Select Instance' page including RS. I've seen this issue on 2 of our SQL 2008 R2 Servers already.
(Using win2k, sqlserver2k, framework 1.1) I have an fairly data-heavy application that uses Windows authentication (Trusted connection/aspnet account) to connect to Sql Server. The site uses IIS basic authentication.
On the dev server everything works fine but when I move to the live server things get strange and it starts to crawl along. (Pages load OK but then it just crawls as it loads the datagrids etc. Sometimes it brings back incomplete/incorrect data )
BUT When I use Sql Authentication to connect to Sql Server and there is no problem at all!
Ok, there is something obviously wrong with the live server (which is identical setup to dev)but I dont know where to start.
I've got two applications which both have a database on my MS SQL 2000 server. The problem is, one application must use Windows Integrated Authentication (which it is currently using and cannot be changed) whilst the other application which I'm trying to configure must use a SQL password.
Since the server has already been configured to use Windows Integrated Authentication for the existing database and application, how do I configure the other database to use the SQL password?
My work is using a shared application which accesses a MSSQL 2000 database. To access the application, the folder on the Windows 2003 Server is shared and users can access the folder through a shared drive.
For the application to access the database, it uses an ODBC connection to the MSSQL server which originally used the SA password.
We have recently switched to using Windows Integrated Authentication because we believe it offers a higher level of security. However the only way in which we have been able to enable this is to add the windows users to the SQL server.
The problem with this is that the application sets permissions for individual users on what records they can see within the database. We have found that by adding the windows users to the SQL Server, they can bypass the permissions the set by the application by simply using any application that can use an ODBC connection, such as Enterprise Manager, and see all the database.
One way around this would be to set up domains of users with access privileges to the tables which reflect the permissions set by the application, and configuring a view of the data so they may only see the records that they have permissions to. However to do this would require a high administrative cost to ensure that changes made in the application are reflected in the privileges of the SQL server.
Instead, is there a way the SQL server can authenticate that the ODBC connection is coming from the correct application using Windows Integrated Authentication?
This would allow the applcation to determine security, and stop users from connecting to the SQL server using other applications.
Alternatively, can the SQL server, using Windows Integrated Authentication, also ask the application to supply a username and password?
Any help with this matter would be greatly appreciated.
I am receiving the following error message when attempting to create a new SQL Authenticated login id.
Password validation failed. The password does not meet the requirements of the password filter DLL. (Microsoft SQL Server, Error: 15119)
I have four servers all running SQL Server 2005 SP2 on Windows 2003 Ent. SP1. Of the four servers, only one received the above error message using the same TSQL below.
CREATE LOGIN TEST_LOGIN WITH PASSWORD = 'pvif9dal' MUST_CHANGE, CHECK_EXPIRATION = ON
All four servers are in the same domain, which if I understand correctly, the password policies are therefore inherited at the OS level by the domain. The password being used is within the password policies of the domain.
I'm trying to install SQL Server Management studio 2012 on my Windows 7 (x64) standalone laptop. When I click "New SQL stand-alone installation..." it runs a Setup Support Rules check and always fails "Setup Account Privileges". I've looked into the error and I keep getting that I need to change security rules but I don't have that option in window 7. How do I get around this without having to resort to a computer running Windows Server?
I have Visual Studio 2013 premium installed along with Localdb v11. I just want to connect and manage my database engine through SSMS when developing any application.
I just upgraded from Windows XP Pro to Windows Vista Bussiness and tried to reinstall SQL Server 2005 Developers Edition. After the installation i downloaded (using microsoft windows update) and installed all the service packs for sql and vista available.
My problem is when i open sql server management studio and try to connect to my default instance using windows authentication and database engine, an 18456 error occurs.
I enabled all the protocols and all the ports I disabled windows firewall and antivirus (eset nod32) I installed all service packs available I have also installed Visual Studio 2005 without installing sqlexpress
But nothing happens!
Please i am very desperate, any information will be gratefully accepted.
This is my installation Information

I am running a number of SQL instances on my PC. Within the network, I have think server with various System Center components. For compatibility reasons, some features of System Center 2012 R2 had to be delegated to different SQL databases. My question is, because there is now more than one IP address on my system, and each instance of SQL is assigned to its own IP, is there a way to setup DNS and SQL so the namespace points to the desired IP address? For Instance:
MSSQL2008 instance is set to run on = 11.12.13.1 MSSQL2012 is set to run on = 11.12.13.2 IN DNS: A Record: Mike-PC = 11.12.13.1 A Record: Mike-PC = 11.12.13.2
If I want to use MSSQL2008 by specifying Mike-PC as the DNS name, how would I do that with 100% accuracy? If there is another way to get the job done, I am more than willing to approach this differently.
Say, I have configured my SQL to use Mixed Authentication. Now, I have a applicaiton which uses my SQL Server. The application just creates a database in SQL Server and uses the database to store its information.
This application also has a SYSTEM DSN under ODBC through which it accesses the database. For the application to access this database, should I only use SA (as my SQL instance is configured to use Mixed Authentication) or can I use Windows Authentcation too...
If I should only use SA, do we have a documentation which talks about this.
For using different services of SQL SERVER 2005 which is better... Windows Authentication or SQL Server Authentication? what are the advantages and disadvantages of both?
I wonder if it is possible to set forms authentication for report manager but leave report server "as it is". I need to authenticate users from external LDAP and can't use windows authentication for report manager, but I would also like to leave report server open for anonymous users. In that way authenticated administrators could create reports which anonymous users could read.
I tested the Security Extension Sample and got it working when I rewrote the authentication part with my own LDAP authentication.
If I have understood correctly, the report manager is just application inside report server so is it possible to use forms authentication with one application but still leave the report server with Windows authentication?
Hi, I am trying to create a new login with a password. I go to Microsoft sql server management. Right-click on security and create a new login with a custom login and password.I use sql authentication. Now after creation if I check the property of the login, the password is the of same length as 'sa'. The problem is I dont know 'sa' password even. (I use windows authentication to connect to the server.) I need a proper uid and pwd for my .Net application access. Please help Thanks Rashmi
I am in the process of rolling out a sql server 2005 enterprise install and had a question regarding authentication. We will be providing sql hosting for a number of groups on our campus, many who are not using our campus-wide active directory, though they all have an AD account.
Windows authentication via the management studio appears to use your AD authentication tokens and will not allow them to enter a username/password combo. Is there any way to configure this?
I would like to use our campus AD for obvious reasons but if there is a requirement for passing tokens this isn't going to work right? It's also going to make database mirroring more of a challenge.
Hey there, I have a table [user] in a SQLExpress database [Database.mdf] in the App_Data folder. There are two columns. [userId] and [password]. I want to authenticate the user who wants to log in through a Login control. the user should have his userId and password in the [user] table. I digged and made my code. but it doesn't work it keeps giving me that the user is not authenticated. i guess it has no errors. please tell me if you find the error. here is the code: 1 protected void Login1_Authenticate(object sender, AuthenticateEventArgs e) 2 { 3 SqlConnection conExpress = new SqlConnection("Data Source=.\SQLEXPRESS;Initial Catalog=Database;Integrated Security=True;User Instance=False"); //Create the server connection 4 5 try 6 { 7 string id_user = Login1.UserName.Trim(); //Get the username from the control 8 string pass_user = Login1.Password; //get the Password from the control 9 10 //These are a sql and connection Examples 11 string sql = "SELECT userId, password FROM user WHERE userId = @param_Id AND password = @param_Password"; 12 SqlCommand comSQL = new SqlCommand(sql, conExpress); //Create the sql command using sql string and sql connection 13 14 //Add the sql parameters 15 comSQL.Parameters.AddWithValue("@param_Id", id_user); //New on VS 2.0 16 comSQL.Parameters.AddWithValue("@param_Password", pass_user); 17 18 string cod_user = ""; 19 string name_user = ""; 20 21 //Open database connection 22 conExpress.Open(); 23 SqlDataReader dr = comSQL.ExecuteReader(); 24 while (dr.Read()) 25 { 26 cod_user = dr.GetValue(0).ToString(); //The coduser is unique onto database table 27 name_user = dr.GetValue(1).ToString(); 28 } 29 conExpress.Close();//Close Database Connection 30 if (cod_user != "") //The user exist onto database 31 { 32 //Create the session vars 33 Session["coduser"] = cod_user; 34 Session["nameuser"] = name_user; 35 e.Authenticated = true; //Grant the access, Goes to DestinationPageUrl 36 } 37 } 38 catch(Exception)//On Login Error 39 { 40 e.Authenticated = false;//Confirm that you are out 41 conExpress.Close();//On any error case, close the database connection 42 } 43 }
