HELP: ASP.NET Won't Connect To SQLexpress After De
Jul 31, 2007
Hello,
I have finish building my ASP.NET site using VS 2005 and it compile just fine. Than I try hosting it to the web via IIS v5.1 and I am getting permission error from SQL express.
I have posted a detail question in experts-exchange.com and since you need a user account to even view the thread, I have taken the liberty to save the thread as .html file and host it to my ISP site. You can see the detail problem I am having here: http://users.accesscomm.ca/mm/EEdetail.html
I am going to list out some stuff I have done:
1. I have two database that need access, the ASPNETDB.mdf for user login and another database (PhotoDataBase.mdf) to store information relating to the photo I uploaded to my ASP.NET site.
2. I have already follow this How to site: http://blogs.msdn.com/sqlexpress/archive/2005/05/05/415084.aspx and setup:
- TCP/IP enable, as shown here:
- I have started SQL Browser service
- The firewall part I am not so sure about. I am currently using Zonealarm....
3. I have installed SQL Server Management Studio Express(SSMSE) and attach the two database to it.
4. I have set SSMSE server properties to accept both SQL and window authentication.
5. I have made sure that both database "read only" setting to false
6. I have setup SQL login with User ID = SQLLOGIN
Here is the original connection in web.config:
<add name="ConnectionString"
connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|Da
taDirectory|PhotoDataBase.mdf;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient" />
and here is the new connection I just type in web.config that replace the original one:
<add name="ConnectionString"
connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|PhotoDataBase.mdf; Server=MINGDESKTOP; Integrated Security=False; uid=SQLLOGIN; Password=XXXXXX;"
providerName="System.Data.SqlClient" />
and the error i get are the follow:

Hi, I'm using Microsoft SQL Sever Management Studio Express. But all of a sudden, if I clicked connect button, the messageBox pops up and it doesn't let me connect. It says "TITLE: Connect to Server ------------------------------

whenever i try and choose the database i wish to work with like below. I end up with an error message about the user not being associated with a trusted sql server connection
i figured this was all permission based so i kept dorking around with security adding my user name to anything i could find, and also went through and dozen or so connection strings and found when i take out the DB name that i can open a connection.... as the code below works...
I plan on importing another database so how will i later on choose between the two, i notice i can create logins only at the security for the sqlexpress and not for my database? did i mess up how i created the database? i have added my username and given permissions to the security for the database i wish to connect to, but is there another step im missing? i would keep trucking but i would like to have multiple DB on the sql express and pick and choose at the code level, maybe im misunderstanding what the catalog should include or i can change the connections database at another point?
I am trying to use built-in login authentication using SQLExpress (SQLMembershipProvider Class). I have run the utility "aspnet_regsql" both with and without the following switches "-E -A m". Either way it fails to connect and tells me I may need to enable remote connections. I have done that and set it to use both TCP/IP and pipes, even though the connection is local. I still get the same error message. If I open up SQL Server Manager, I can see that there is a user account set up for ASPNET.

I have set up a database in SQL Server 2005 (The express version) and am trying unsucessfully to make a connection to it from MS Visual Web Developer 2005 Express version. I always get the same error: "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this error may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - could open a connection to SQL Server)" How can I set up SQL Server to allow remote connections? I am trying to establish a connection from my web page to this database. Is there a user that I need to establish on the SQL Server side?
I am trying to connect to a SQLExpress installed on Vista through the network. I did enable all protocolls and in the Surface Area Configuration I activated Remote Connections ("using both TCP/IP and named pipes"). But still I get the following error:
"An error has occured while establishing a connection to the serveR. When connection to SQL Server 2005, this failure may be caused by the fact that uder the default settings SQL Server does not allow remote connections. (provider: SQL Network Interface, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server)"
I have installed SQL Express 2005 on a machine and I am trying to run a script file via SQLCMD from my application. I keep getting an error stating that SQLCMD can not connect to the server. Remote connections are enabled for both tcp/ip and named pipes. Sql Browser Service is enabled and running.
This is the error message HResult 0x2, Level 16, State 1 Named Pipes Provider: Could not open a connection to SQL Server [2]. Sqlcmd: Error: Microsoft SQL Native Client : An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.. Sqlcmd: Error: Microsoft SQL Native Client : Login timeout expired.
I can open Management studio and run the script and it works perfectly so I don't really know what is going on. Thanks for any help.

Please help! I am really running out of ideas.... and I need to have this setup in a few days....
I am trying to set-up membership options on my MS Server 2003.
I also have a Computer running MS XP Professional sp2.
With the Advanced in stall of SQLExpress - trying to establish cojnectivity on the server fails when using the ASP.NET Configuration button.
This works fine on the XP box.
On the security tab the following message apppears:
There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store.
The following message may help in diagnosing the problem: Unable to connect to SQL Server database.
I've compared all settings in ssemee, surface manager etc. - all identical.
run aspnet_regsql on both machines. Added the SERVERASPNET account to SQLExpress and to the aspnetdb database.
I've enabled TCP,remote connections, named pipes etc. to no avail.
Any suggestion as to what the error could be would be most appreciated - been trying now for 3 days to get this working without any success.
Please if any one can answer.I am developing .net vb app sqlexpress database.
In single user work ok.In multiuser from other computer on network I cannot get data.Any form without data workok fine . The error I am getting is as follows.
Application attempted to perform operation not allowed by the security policy.
I am using the following connection string to connect to SQL Server 2005 Express Edition installed on my local PC. string sqlstr = "Server=(local);Database=MyDB;User ID=sa;Password=sa;Trusted_Connection=False";
And it gives me the following error. The string works fine in computer with SQL Server 2000 instance but fails with 2005. The string also fails for "Server = localhost". However the string works very fine if I use the name of Server 2005 i.e ./SQLExpress
===================================
Cannot connect to (local).

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (.Net SqlClient Data Provider)
Now the main problem is that, of course I could use a named instance, but since I am embedding the Connection String in a dll file so that any user can use it to connect it to the local instance of the SQL Server 2005 installed in his/her computer, I need to use "server = localhost". Doesn't SQL 2005 support this. If yes, where could i find option to enable it?
I have enabled every option available in surface area configuration for SQL Server 2005, but nothing seems to help out. I even use local as well as remote connections using both TCP/IP and named pipes. Can nyone help me out?
I installed SQL Server Express and SQL Server manager, then tried to start manager. SQL Service is running, but SQL Manager attempt to connect to SQL Server instance times-out even though I correctly identify instance as SQLEXPRESS? Everything seems to be normal - both SQL Server and Manager are on a single Windows XP home machine. Any suggestions. Thanks
Here is my problem: I have SQLEXPRESS running with Windows Authentication on a "server" PC named "ASUS1", and I need to connect from a "client" PC named "Presario1", user "Mauro", connected through a peer network (I use a cross-over cable); both PCs belongs to the same workgroup named "RMT-WORK", and they can see each others shared folders without problems.
I have installed the connectivity components + Management Studio Express on Presario1, and enabled named pipes and TCP/IP protocols; then I've got SQL Browser running. I have also added the Login "Guest" on ASUS1SQLEXPRESS.
When I start Management Studio Express on Presario1 and browse for servers I can select "ASUS1" as database engine but when I try to connect I receive "Error 40: could not open a connection to SQL Server" (same result using SQLCMD); I have tried to add on ASUS1SQLEXPRESS a user "Presario1Mauro" with "CREATE LOGIN [Presario1Mauro] FROM WINDOWS" but I receive a "Windows user not found" error...
I have to deal with a private network of laptops which are all equiped with preinstalled "Windows XP home"
I've installed SQLExpress on one of these, but I cannot connect on it from the rest of the laptops. (I've successfuly done this with "Windows XP profesional" though, and local connections work fine as well).
I've already setup the SQLExpress to accept conections throuigh TCP/IP but I can not think of something else. (Security comes to mind, but I do not know how to resolve it on "Windows XP Home").
Hi all,I'm having a big problem here. I can't seem to connect to a database of MSSQL Server 2005... Here is what I've did:1. Under the Server Explorer>Data Connections. Right click and choose "Add Connection..."2. Data Source was "Microsoft SQL Server Database File". Click OK.3. I browse to the database in the MSSQL.2/MSSQL/Data folder.4. Click on the "Advanced" button, and change the default DataSource from .SQLEXPRESS to .MSSQLSERVER. Click OK5. Received this error:An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default setting SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid) Only .SQEXPRESS that I was able to connect to... i've tried the solution from Microsoft, opened SQL Server 2005 Surface Area Configuration and enabled "Local and remote connections", checked the option "Using both TCP/IP and named pipes" but it didn't help. This is frustrating because I can't get the Membership provider, login to work on my host. Please help. Thank you very much,Kenny.
Hi all, I'm having a little trouble connecting to a SQLExpress instance on a remote domain using SQL Server Management Studio Express.I've read that by default the program is set up locally only, so have edited the Surface Area Configuration. It only gives me the option to edit 'Services and Connections' on the localhost, but have edited the Remote Connections to use TCP/IP and Named Pipes. In the Management Studio, I enter the server name, and login credentials. On the Connection Properties tab I changed the network protocol to TCP/IP though everytime I attempt to connect I get the following error message: Any help would be greatly appreciated. Rich
The SQL ERRORLOG shows: Error is 3414, Severity 21, State 2 and says: "An error occurred during recovery, preventing the database 'model' (database ID 3) from restarting." Just prior to this, I get a warning: "did not see LP_CKPT_END".
Any thoughts why this might be and how I can fix this?
I have created an installation application which will install the application with SQL Express and .NET Framework 2.0.
If i install this application in a Fresh system(i.e which is not having SQL Express), it is installing the application with new database instance successfully.
But if i try to install the same in a system which is already having SQL Express, throwing "Object reference exception" because it is not able to create the new database instance.
Because of numerous problems trying to get sqlexpress working, I uninstalled it with the intention of reinstalling (via Add or Remove Programs). However, now when I try to reinstall it, I get a message that the I am not making a changes so it won't let me install it.
I do have sql server 2005 developer's edition installed; is that the reason? and does that mean I cannot have both installed on the same machine?
Hi All,I've been struggling with this for hours...Could someone please advise me on how to convert my current File based SQL Server Express website to a Server based SQL Express one.Particularly interested in what I need to do in the SQL Express management tool, changes I need to make the projecvt itself and changes needed to get IIS to understand things have been changed.Thanks,Martin.
I designed the AlwaysOn wrong, but every time we fail over from primary server to another server, my applications cannot connect because the sql logins cannot connect to their default databases. Once I run the command to link the login with the user in the default database then the users are able to connect. Did I do something wrong when designing AlwaysOn?
I try to import my SSIS packages which are created using the Business Intelligent studio into SQL server 2005 but I cannot do that.
I am running SQL server 2005 enterprise edition.
Also when i tried to connect to Integration services using Object explorer, it only prompt me for server name. I cannot change the username and password which is disabled.
Then how am i supposed to connect to Integration services on a server in this case?
I'm having a problem connecting with a Java application but I CAN connect using my .Net application - the user name and password are the same for both (using the same database on SQL Server Express 2005).
The error I get is: "com.microsoft.sqlserver.jdbc.SQLServerException: Cannot open database "CORNERS" requested by the login. The login failed." An interesing note - I get the same message if the database is not running.
SQL Server Express 2005 is installed in mixed mode.
Here is my connection string in the .Net appplication: <add key="connectString" value="Server=(local);UID=sa;PWD=myPasswd;Database=CORNERS" />.
Hi I'm pretty new to all of this. I downloded a starter kit and am a bit confised as to SQLExpress. I have SQL Server already installed and just wondering what the option are. I am currently using Visual Web Developer Express Edition and in the config file data source is SQLExpress and can't go any further. I don't want to mess with my current setup so just want to get some sugestions first. Anyway hope this makes sense. Thanks GP

I am new to this forum . I am running through few problems for sqlserver account settings .
I) My registery key entry for MSSQLserver just has a client folder . 2) My sql server configuration manager just has sqlserver 2005 services , native client configuration and 2005 network configuration.
I can't see any server name or databases under it.
3)I normally work on EMS lite so I can see my ./SQLEXPRESS as server and databases under it and i can create logins etc ..I assigned db_owner role to one of my recent created database. but when I try to connect it says :
The user is not associated with sqlserver connection.
5) i have sqlserver express service running, vss and sql server browser running.
I googled and searched for the solution and it says the authentication mode should be turned to mix mode form win authentication.
But from where. Have i missed some installation .I am able to connect to my other database from EMS.
I am trying to write an application for a MSSQL database, using SQL Express,and Visual Studio (Express edition)I tried to connect to an existing database (named testing) but to no avail.Visual Studio claims the database does not exist.Any ideas?TIA--Q: What is the difference between a mathematician and a philosopher?A: The mathematician only needs paper, pencil, and a trash bin for hiswork - the philosopher can do without the trash bin...
Installation of SP2 in step "Feature Selection" shows SQLEXPRESS unchecked and can''t be edited/checked. I tried it many times on different servers with different OSes, etc
Does it mean that SP2 for Expres Edition should be downloaded and applieŠ² separately?
