I have a question relating to SQL Server management studio,
I have downloaded the SQL Server Express onto my PC and was told to expect SQL Server to prompt me for a username and password, which I could use to login as "SQL Server Authentication", and use the login and password function.
I followed every single instance of the Installation but was never propted about any such password and user name setting having to be created.
Big deal however I need to practice methods for loging into SQL Server using password and Username functionality ussing vb.net (Automating login procedures).
What are the steps I need to undertake to make correct this?
The Authentication Mode can be changed at any time. In Microsoft SQL Server Management Studio, right-click on your server, and go to properties.
In the Security page, you have the option to change the Server Authentication mode to Windows or Both (Windows and SQL).
Make sure the "sa" user has a strong password (it may be empty or disabled by default).

I installed Windows Server 2008 and SQL Server 2008 R2, after joining to domain I changed computer name and mistakenly I deleted the administrators group from SQL Server login users and now I am not able to login.
Any suggestion?
I know this is old but I just used the Gui instead.
Step 1. Start SSMS
Step 2. Select the server name drop down and click browse more.
step 3. select local or network tab based where the server is and expand Database engine and select the correct computer name\sql server
Follow the steps in this article: http://v-consult.be/2011/05/26/recover-sa-password-microsoft-sql-server-2008-r2/
Basically you have to modify the SQL Server Service settings so that it starts in admin mode. This will only allow one connection to it. Once you start it up you can create a new sysadmin user that you can use from then on.
Also I do know that you need to run certain scripts on a SQL Server if you change the hostname of the server. You should find them if you google them.
If you have mixed mode authentication enabled on the SQL Server instance, you can login using the sa account, with the password that you specified during installation.
If you have only Windows authentication enabled, I'm not sure. You could try running setup again and seeing if it will let you change the authentication mode, but somehow I doubt that it will let you do anything without first connecting to the instance with your Windows identity.
As a last resort, you could try uninstalling and re-installing the SQL Server instance, then re-attaching all your databases.
Add the new name of the computer and you should be able to login again..
We currently use SQL 2008 with Windows Authentication disabled, we only allow SQL Mixed for accessing SQL.
We are wanting to switch our version control software to Team Foundation Server, which requires Windows Authentication.
Which ended up being a bit of a problem, I've talked to our DBA and Windows Authentication is not an option, nor is putting SQL on the server where TFS will reside.
Issue is, from what he is telling me, you are unable to just enable Windows Authentication just for a single user, its either on or off for all users.
Is this correct? What other options are there?
You need to have another talk with the DBA.
There are 2 options for authenticating to SQL Server:
Windows Authentication (only)
Both Windows Authentication and SQL Server Authentication
Yes it is true that if you turn on the latter option also known as Mixed Mode, and it applies to the server (which will now accept Windows Auth) - it does not mean that suddenly all valid Windows users will get access to SQL Server!
The Windows logins still have to be added as SQL users (SQL login != SQL user[principal]) and they can then belong to roles etc, so you would only need to add the users for TFS.
In fact, you cannot possibly disable Windows Auth - so I don't see why the DBA should be complaining about "turning on" Windows Auth.
This is probably what you need to do:
Add a new domain group "sqltfs"
Create a SQL user out of the Windows security Group "domain\sqltfs"
Grant all the access required to the new user (or indirectly through a role)
add all the TFS users into the domain group "sqltfs"
This way you can all continue to use SQL logins where it matter (existing code), while still gaining access via TFS -> SQL Server through the domain group membership
This probably belongs on superuser, but I'll take a stab at it. From my SQL 2008 R2 management console, the DB server can run in either pure Windows Auth mode, or mixed Windows auth + SQL auth. It can't run in SQL auth only.
Since you say you're in mixed mode, I can't see why he can't add another user to the DB that uses a windows domain account, rather than a local SQL server account. Mixed mode allows both.
I authenicate to my SQL Server instance by logging in with a Windows account via SQL Server Management Studio. I want to change this to a SQL server login.
How can I do that?
The default installation of SQL Server only supports Windows Authentication.
If you want to use SQL authentication (e.g. "sa" for the superuser), you need to:
Using SQL Server Management Studio, connect to the server. Use Windows Authentication for now.
Right-click on the server instance you want to modify. This is usually the root item in the tree in the left-hand panel.
Select Properties from the context menu.
In the Server Properties window, select Security from the left-hand panel.
Under Server Authentication, change the radio button from "Windows Authentication mode" (the default), to "SQL Server and Windows Authentiation mode".
Now you can create SQL server logins which you can use to connect to the server.
When you first open Management Studio it asks you what credentials you wish to use to login.
For an actively connected session you need to change the current connection using the button on the tool bar (normally top left) which will pop up the login dialogue again.
Clearly this will depend on you having some SQL Server logins already defined on the server with appropriate permissions specified.
how do i convert my sql server management studio express to server authentication mode.. please help regarding this..
I assume you mean SQL or Mixed-mode Authentication (the ability to login using your SA account). Follow the instructions in this link.
You should be able to connect to it as normal via whatever method you already have (this requires sufficient Admin permissions).
Then to enable access via SQL Logins you can
Right click on the instance name in Management Studio (mine is localhost\SQLEXPRESS (SQLServer 10.0.1600)).
Go to the Security tab.
Then you should be able to enable SQL Logins by clicking SQL Server and Windows Authentication Mode.
Click ok and you're done!
You can now add SQL Logins as connect via them as you would normally.
I just created a new database in "Microsoft SQL Server Management Studio Express" and now I'm in "ColdFusion Administrator" and I'm trying to add my database as a Data Source. How do I do that? I believe the servername is .\SQLEXPRESS but I'm not sure what the default username and password are. I've tried creating a new login through Management Studio with an actual username and password, but those aren't working either. The error I'm getting is:
Connection verification failed for data source: xxx
java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]The requested instance is either invalid or not running.
The root cause was that: java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]The requested instance is either invalid or not running.
I can see that the service is running, and I can connect to it through management studio. I've tried following a couple tutorials online, but they don't seem to be working for me. Ideas?
Server name can be any resolvable hostname or domain name, in case of having SQL Server and CF server on same box localhost should work for you.
Also make sure that user you created has access to the particular database and needed operations. Look into the database permissions for this. This check is not required when using master account (often login is sa), but this is not recommended practice because of the security reasons.
Also make sure SQL Server and Windows Authentication mode is checked. I had an issue with permissions as well when I only had Windows Authentication enabled under:
right click on server (localhost) -> security
Then restart SQL Server Services to save changes. After that I was able to connect my ColdFusion datasource to SQL Server.
For testings sake use the same credentials that you are connected with in Management Studio, likely the "sa" user and password. Once you have it working with "sa" then go back into Management Studio and create an application level user for your CF app and then update the data source to use your new user / password.
