Change Authentication Method In A Local Database File
Apr 13, 2007
I have made a small asp.net project which uses a local database file as a part of the project. The project is running fine om my local machine, but when I upload it to the remote server, the login fails for the server.
I suspect this is can be solved by using sqlserver authentication. But I have now spent a lot of time trying to configure the database file to use this authentication mode. As I see it there are three possible solutions to the problem.
use management studio express to configure the local mdf file (Ecxept that I cant find out how to connect to the mdf-file) and from here change the authentication method to sqlserver authentication.
use Visual Web developer to change the authentication method (but how???)
make the windows authentication work on the server (this would probably require that mannamgement studio express connects to the remote database. (Same problem as no 1)
I am wondering if we could back up the databases to any place outside of the local server system? As I found, we can only back up the database to the local server system, so we have needs to share databases on network places. Is there any method to back up the database on network place rather than first of all I have to back up the database on a local server system, then copy it to the network place, that just sounds really inconvenient.
Thanks a lot in advance for your help and I am looking forward to hearing from you shortly.
I attempted to setup database mirroring using a High Availability scenario but when I installed SQL is chose to use local system accounts for all the services. Consequently, I stubled upon a microsoft article explaining how to setup mirroring using local system accounts and certificate authentication but I am stil not able to get it to work. When I try ti initiate the mirror from the mirror server I receive an error stating "Neither the partner nor the witness server instance for database "EDENLive" is available. Reissue the command when at least one of the instances becomes available." I have checked all the endpoints and everything seems to be in order. I even checked to make sure that each server was listening on the appropriate ports and I AM able to telnet to the ports. Please help!
Hi, can I assign a NAS(Network Attached Storage) server to store the database file(readable and writable) and assign other several MS SQL database servers which will use the same database file in NAS to achieve the objective of high availability?
If it can, how can I set it up in MS SQL Server or it requires another 3rd patry software to set it up?
I am unable to connect to my local sql server express db. I would like to test my app and its not connecting. It works when I use windows authtentication Trusted_Connection=yes but not when i use: user id=sdvaid; password=sdavid
Dim conn As SqlConnection = New SqlConnection(connectionString) Dim cmd As SqlCommand = New SqlCommand("select * from Users", conn) cmd.CommandType = CommandType.Text Try conn.Open() cmd.ExecuteNonQuery() Catch ex As Exception Response.Write(ex.ToString()) Finally
conn.Close() End Try
thanks.
Here is the error: "SQL Server does not exist or access denied."
Hi, I'm trying to work on a database when I'm not connected. I can't figure out how to get a local copy of a database.mdf that I created on the server, onto my hard drive, using SQL Management Studio Express. Does anyone have any suggestions? I'd be forever in your debt. Thanks
Currently, my (small) intranet site is storing it's data on a remote SQL server. The danger with this, as has happened several times now, is that the application is twice as vulnerable; if either the webserver or the dataserver malfunctions or is unreachable, the application won't work.
I only recently discovered the possibility to use local database files (MDF files), and this seems like a much better solution for my site. But now I want to transfer the tables that are residing on the dataserver, to the MDF file. The database only contains tables. How do I handle this? I do not have access to the dataserver, only to a few databases that are residing on it. Is this possible using Visual Studio 2008? I have read about a "Bulk Copy Program" (bcp) which is included with SQL Server, but I cannot find a download for just that application.
Or is this totally not the way to go? I've discovered MDF files are a bit more problematic with concurrent connections; having tables open in Visual Studio results in "Site offline" or "Cannot open database" error messages on the website. Problems I've never had to deal with using SQL Server, but they are only minor problems.
I am using the following C# code to establish a SQL connect to a SQL database file:
// connection string // attach a SQL database file to a local SQL server express instance string _connectionString = @"Server=.SQLExpress; AttachDbFilename=C:BalanceDatabase_1.mdf; Trusted_Connection=Yes; User Instance=True";
// using System.Data.SqlClient; SqlConnection _sqlConnection = new SqlConnection(_connectionString); // open the connection _sqlConnection.Open();
// do something
// close the connection _sqlConnection.Close();
So far, the connection works fine.
However, next, I want to copy the database file to another folder. So the following codes: // source database file name string sourceDatabaseFileName = @"C:BalanceDatabase_1.mdf"; // target database file name string targetDatabaseFileName = @"D:BalanceDatabase_1.mdf"; // copy database file System.IO.File.Copy(sourceDatabaseFileName, targetDatabaseFileName, true);
Then the program came with runtime exception: "IOException was unhandled: The process cannot access the file 'C:BalanceDatabase_1.mdf' because it is being used by another process."
Is it because the database file was sill attached to the local SQL Server express instance? What can I do to bypass this problem? Detach the database file? or dispose the local SQL Server express instance?
I have a web app, designed using VWD Express and using SQL 2005 Express. It has a mdf database called "client". It was created using security of windows authentication. I have already changed my instance of sql server express to accept mixed windows and sql authentication. How do I change my "client" database's permissions to the sql authentication? I need to add a user name and password as a requirement for my web host to be able to attach the mdf to their instance of sql 2005. It has to be the same user and password as I use with my web host's sql server 2005. Thank you in advance.

Change the Authentication Mode of the SQL server from "Windows Authentication Mode (Windows Authentication)" to "Mixed Mode (Windows Authentication and SQL Server Authentication)".
I have a database I need to copy from a Prod server to a Dev server. There is not enough space on the Dev server. In looking at the size of the files on the Prod server, the Initial Size property for the transaction log on the Prod server is set to 100,000 MB though the log is using nowhere near that.
This is a mirrored database so the recovery model is "full". I know that to change the initial log size, I have to put the database in 'simple" recovery model. Is this possible? Can I just:
1. Pause the mirror 2. Switch recovery model to simple 3. Change the initial size property to something smaller. 4. Shrink the transaction log 5. Change the recovery model back to full and resume the mirror?
I honestly don't know if the transaction log is needed on the Dev server. Meaning I may just be able to restore the transaction log to a different location on the server and delete it so that new one is created.
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.
Hello- I recently inherited a SQL 2005 Standard database that I am being asked to change the Server authentication mode for. SQL system is managing a local database for Microsoft Systems Management Server 2003. Currently the system is running in SQL Server & Windows authentication mode. I am going to change it to Windows Authentication mode. Can someone point me to a checklist I could refer to before I make the change to be sure I don't take down my database?
Hi,Does anyone here know whether it is possible to change theauthentication method of a SQL server instance programmatically, ratherthan going through enterprise manager.I am using SQL-DMO (under C#) for some other things, but thedocumentation is so bad that I can't find out whether what I want to docan be done. I have also tried googling but came up empty handed.I hope that someone can help me.CheersJono
Hello, I have several SQL 2000 logins on our servers. I removed the builtin/ groups and only have SQL authentication users, although the server is operating in "Mixed Mode". How can I secure this? I don't understand how we can just connect to any DB without ever being asked to log in. Let me know if you can help. Thanks.
I installed SQL Server 2005 using Windows Authentication Mode (Windows Authentication)"
How can I change the Authentication Mode of the SQL server from "Windows Authentication Mode (Windows Authentication)" to "Mixed Mode (Windows Authentication and SQL Server Authentication)"?
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
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.
Hi all, I've read up on the fact that if you use SQL server 2005 instead of SQL express you need to change the connection string in web.config. Is there anyway to make this default connection type, or do I have to do it for every website I create. i.e. is there a global file that this connection can be entered into. Then whenever I start a new website I don't have to put the string in. Just me being lazy really. But it's nice to know if it's possible.
I use the Mangement Studio Express to manage a MSDE 2000 instance and notice that the Server authentication area in the Security is disabled for that instance. But for an Express instance, the Server authentication area is enabled. Is this difference caused by some settings?
Just spotted that some cowboys install a Live DB Server using Local System Account for the SQL Server Service. Gonna change it to a Domain Admin Account tonight. Anyone got any advice or warnings about any "gotchas" I might run in to during a job like this?
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:

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 am facing a problem in connecting to the local database with server name as (local).
I have installed SQL Server 2005 in my machine. When I try to connect to the SQL server with the server name as SUNILKUMAR I am able to connect but when I try to connect to the same server with the server name as (local) I am not able to connect. SUNILKUMAR is my machine name and SQL server is running locally.
if anyone can help me what is the problem in this case it is highly appriciated.
My goal is to develop the system on a windows application and pda
There is a central server which will create a publication called inventory
The laptops which host the windows application will be subscribers to the central server using merge replication
The client now wants the PDA using SQL Mobile to synchronize with the local subscirber database on the laptop using active sync. They dont want to do it via WIFI to the IIS Server at the central server
I have been reading for days and I am still unsure whether this is possible to do.
I know Appforge provide a conduit for palm to access synchronization but not local sql databases

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.
