Who Is The Default Owner For Sql Express In Windows Authentication Mode?
Aug 1, 2007
If i create a database in sql express in windows authentication mode, the database owner is in the format of 'MACHINENAMEUSERNAME'. If i connect this database to iis server i got login failed error message.
This is my connection string in my web.config :
Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=True;Initial Catalog=dbsgh;Data Source=software92sqlexpress
I solved this problem by creating a login in sqlexpress called 'software92/aspnet' and creating a user for my database named aspnet under 'software92/aspnet' login. Then i changed the usrename in directory security of my iis virtual directory to 'software92/aspnet'.
This solves my problem. But i think i m solving this problem in a wrong way.
I think i should create that database under default owner. Who is the default owner?
I dont know the correct procedure to solve this.
Please help.
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
I am trying to create a query that can determine if a user id is using mixed mode/windows/both authentication. I need to do this so that it can run on both sql server 2000 and 2005, meaning I can't use any of the sys.* views. Is there a single query could use for both systems? -Kyle
We have SQL server 2000 on windows 2000. From our desktop MS Access was connected to database through ODBC. Since yesterday (after our consultant had updated another asp application in the same server) we are getting €œSQL Server Error: 18452. €¦.. Login failed for user €˜(null)€™. Reason: not associated with a trusted SQL Server connection. €œ
The consultant saying he did not touch any settings on server (?). And the problem is even server€™s security property shows it has mixed mode authentication. But I cannot connect to server even through my SQL server enterprise manager in windows authentication mode. I can connect if I use SQL server authentication. Through ODBC I can connect also and test fine, if I use SQL authentication. But the Access application wouldn€™t connect using SQL authentication in ODBC.
So, can any one help me to find out what else could be done to make sure that the server is going to accept windows authentication. I€™m thinking any other settings or registry change €¦ etc. Please help.
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.
Having problems connecting to SQL Server Express using 'sa' account and having read threds re problem and MS, advice is that Authenticaion mode needs to be set to both Windows and SQL. I have studio express installed and go to Security from the properties of the Server to change this option to use both authentication modes, however the options are greyed out!
Can anyone advise pse.
And will amending this option help me to enable the sa login which is refused at the moment, error as follows:
Login failed for user 'sa'.The user is not associated with a trusted SQL Server connection
In testing, several people are testing on laptops.
The database on SQL Server Express is local, on the laptop. So is the client applicatioon. When they unplug from the Network, and go home to work, we get "Cannot Find Server" problems.
Why is this? Windows Authenentication turns off? or is it the fact that TCP / IP is open?
What can we do? If we use the SQL Server Authentication, it works.
If we shut down, plug into the network, restart, it works.

Has anyone else experienced SQL Express resetting to Windows Authentication only instead of mixed mode for logins after a power failure. I only noticed it happen today as we had 2 power outages in the office and it happened both times. If anyone has seen this happen or knows of a fix please let me know.
I have a SQL 2005 OTC. CTP version running on Windows 2003 server.
I would like to find out how the SQL server option changed to Windows Authentication mode from Mixed mode over the weekend. From the SQL log, I don't see when it changed. I would like to see Date/Time and client IP. If I can see User ID (windows) that would be great. Where I can find these info in SQL server?
(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 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

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?
Although I am in the DBO role, whenever I create an object I am put in as the object owner. For the way our database is set up, all of our objects are owned by DBO, and it can be a pain to have to remember to set the owner when creating an object. In 6.5, if you were aliased as dbo, all objects you created were owned by dbo. This is the functionality I'm looking for.
Is there any way to have dbo be the default owner of an object when it is created? Again, I am in the dbo role.
HiOverview - non-sysadmin access to SQL 2k box using 2k5 tools. Not used 2k in over a year,Any way to set the default owner for objects created by a user? So if user x runs: CREATE TABLE mytable ( mycol BIT ) it is owned by dbo not x (dbo.mytable not x.mytable)? Note I can't (or won't for now anyway) change the DDL above. I also don't believe I can do this with the SSMS tools (schema <> owner). I also can't use sp_adduser...So 2k comliant T-SQL or at a push SMO only please!Ta
Were working on a Smart Client application. Our customers will have .Net Windows forms on their computers that will access SQL Server data on our server.
I've read that Windows Authentication is the most secure authentication mode. However, since our customers computers are not on our network it would be impossible to use Windows Authentication. We'll have to use Mixed Authentication. I just wanted to confirm this in case my understanding of the authentication modes is wrong.
I folks.I Have installed sql server 2005 express and choosed windowsauthentication on instalation, but i make a mistake and now i needmixed authentication, how can i modify this whithout uninstall andinstall again the application?thanks for the help.
Hello,I have an SQL Server 2005 database that I'm trying to create using script.Everything works fine, but when I click on "Database Diagrams" I get anerror message that there is no database owner, and of course when I show theDatabase Properties, the database was created without one. Is there any wayto ALTER AUTHORIZATION to a default owner or system administrator, somethingvalid?Any direction would be appreciated.Thanks!Rick
I'm getting the "This database does not have a valid dbo user or you do not have permissions to impersonate the dbo user,...." error message when trying to add a Database Diagram from Visual Studio Server Explorer.
I can add the diagram without a problem from SQL Server Management Studio Express CTP.
When I view the properties of the database in VS, the owner shows as XYZMyOldUserName. This is wrong. I just added this database to a new project.
When I view the properties of the database in SSMSE, the owner shows as XYZMyNewUserName. This is correct. It shows the name I am logged onto the PC with.
I'm logged onto a domain using Active Directory. I renamed my user logon name from MyOldUserName to MyNewUserName a couple weeks ago. Now, VS is still picking up that old name somewhere and, despite it showing properly in SSMSE, it does not show properly in VS.
Where is that old user name stored? Why does it essentially show the database as being owned by two different users? (well, at least, the same user with two different names.)
<P Hi Everyone I changed the authentication mode from SQL Server Authentication into Windows of my application (Web application - ASP.NET 1.1, SQL Server 2000, C#). I changed the SqlServer into Windows only mode authentication. The SQL server now contains all the "windows users" as users of the database (Logins as well as Users). But I faced the problem of 'login failed for NT AuthorityNetwork Service'. So I added the Network Service as user. The login problem is disappeared, but when I'm tracing through the SQL Profiler I can see only the Network Service as user and not my windows usernameSQL server login name. what should I do for displaying the windows usernameSql login name in the profiler instead of "Network Service". Please help me.

I would like to set 'SQL Server and Windows Authentication mode' of Sql Server 2005 so when user connects to Server he must supply username and password. Here are steps I make :
1. Open Microsoft SQL ServerManagement Studio Express 2. In Object Explorer right click on first (Server) node 3. Select 'Properties' 4. Select Page 'Security' 5. set 'Server authentication' to 'SQL Server and Windows Authentication mode' 6. press OK 7. in popup window fill password ******** and press OK 8. get error message ''operation is not valid due to the current state of the object. (Microsoft.SqlServer.Express.SqlManagerUI)
