Unable To Connect To Database.mdf(SQL Server Express)
May 15, 2007
Hi, I am trying to connect with Database.mdf(Server Express) which is inside App_data with my ASP.NET website but i am receiveing an error which i have pasted below. Initially i tried using a business Object(.xsd) but while specifying the datasource in DataSourceobject i got nothing using wizard(which lists all the Adapter Methods(insert,select) of my business object) hence i am trying to connect without a business object. i.e just using the connection string(ConnectionStrings:DatabaseConnectionString) but this results below Error. Kindly help:; ------------------------------------------------------------------------------------------ Server Error in '/MapSpeaks1' Application. -------------------------------------------------------------------------------- Unable to open the physical file "c:inetpubwwwrootMapSpeaks1App_DataMapSpeaks.mdf".

just installed a new machine with windows 2003 server and SQL SERVER EXPRESS; I am able to connect to the SQL Server using my windows credentials however I am unable to log on to it using 'sa' (and no password) user; i get the following error message.
2007-05-07 15:42:12.32 Logon Error: 18456, Severity: 14, State: 7. 2007-05-07 15:42:12.32 Logon Login failed for user 'sa'. [CLIENT: <local machine>]
I'm trying to connect a DB in SQL express with a program in VB.NET Express. I'm using the Data Source Configuration Wizzard. When I select the file (.mdf), the following message appears:
Unable to open the physical file "path to my file". Operating system error 5: "5(error not found)".
An attempt to attach an auto-named database for file 'myFile' failed. A database with the same name exists, or secified file cannot be opened, or it is located in UNC share.
I'm using the Windows authentication for this, but if I try with the sa user, I get the following message:
Failed to generate a user instance of SQL Server. Only an integrated connection can generate a user instance. The connection will be closed.
I installed Sqlexpress server 2005 and am able to connect to the server using the sqlexpress manager.
The connection parameters are:
server: 127.0.0.1 (This is an alias name pointing to TMD03SQLEXPRESS) username:sa password:test mode: sql server and windows authentication mode TCP/IP : enabled and listening on port number 1433.
But I am not able to connect to the server using PHP's mssql_connect function.
but none of them works. I also tried OSQL and SQLCMD and they don't work either. They give me the following error message.
[SQL Native Client]Named Pipes Provider: Could not open a connection to SQL Server [2]. [SQL Native Client]Login timeout expired [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.
Can anyone please let me know what am doing wrong here?
I have read all of the posts regarding this subject as well as 3"Dummies" guides and I keep having the same problems. I have a verysimple multi-user application that has to hit a database. Wecuerrently have this system deployed and it is working fine on adomain based network. We are scaling back and the network we will beusing is now a workgroup not a domain.It should be simple. I have XP boxes (clients) trying to hit the SQLServer Express database on a Windows Server 2003 machine. It is aclosed network so security is not an issue. I am trying to make thisthing wide open. All I want is for the user to be logged in on hisclient machine, run the application, and access/update the databasewithout having to re-authenticate to the SQL server. I want windowsto handle all of the authentication between the XP machines and theServer 2003 machine.Any suggestions would be greatly appreciated.
My situation: I have one virtual folder on a customer's server that hosts a web service which connects to Sql Server Express. This has been working for months.
The connection string that i use is: (obviously the names have been changed to protect the innocent) User ID=auser;Password=apassword;Initial Catalog=acatalog;Data Source=0.0.0.0SQLEXPRESS
I have recently added another virtual folder to the server, and it needs to connect to the same sql server. In this case it is a "regular" web site. I have it set up to use the same connection string as the web services site ( I can't think of any reason why it wouldn't be the same), however when I try to open the connection ( when I call mySqlConnection.Open(); ), I get get this error:
I am stumped as to why code in one virtual folder has no problem, while the other does. Both virtual and physical folders are on the same machine, and the Sql Server Express is installed on that machine.
I'm running SQL Express on Server 2003 SP1 (workstation - although, I did dcpromo promote and demote prior to installing SQL Express).
I'm trying to connect from SQL Studio Express on Vista.
TCP and Named Pipes are selected in Surface Area Config; sp_config remote, access..., 1 was run (per KB); ports 1433 & 1434 are open (I think 435 also was opened when I ran the KB instructions); Mixed mode is selected, user is set for SQL Auth, password is correct; all permissions are granted.
I found an article online which stated that mixed versions of MDAC can lead to the problem. The server has 2.82.1830 and the client has 6.0.5600.16834. Could this be the problem? If so, how to solve?
What could be the possible reason for this and how can i configure sql server 2005 express edition to make connections without specifying any portnumber in the connection string. Both the sqlserver database service and browser services are running.
I am trying to connect to sql server from a small c++ program , I am getting the following error
An error has occured when establishing connection to server. The failure may be caused by the fact that under the default settings does not allow remote connections.(Sql network interfaces error no 26 error locating server instance specified )
I chkd the default settings and it allowed remote connections. I also have default instance for the sql server
I am trying to connect to another computer in my local network which has Windows XP installed. It has SQL server 2000. I get an error message 'Time out period elapsed' when i try to connect to SQL server 2000 thru SQL Server Management Studio Express' Please guide.
I have a c# application running on my machine. I want to point to a sql server data base express edition running on other machine. By default, from server explorer Ionly acces data base files of the local machine. I dont have acces to remote servers.
I used the file explorer and opened the mdf file on remote server. I tried to acces the mdf file remotely but i got excepcion.
My questios are:
- Is sql server 2005 express edition supporting remote connection to mdf data base file?
- In other words, I can remotelty conncect to mdf file from remote machine ?
So, I how can point my application to remote sql server 2005 express edition data base running on other machine?

Hi, I am working through "Sams Teach Yourself ASP Dot NET 2.0 in 24 Hours" I am upto hour 20 where it says Configuring an ASP.NET Website to Support Membership To configure our website to support membership, we must launch the ASP.NET Website Administration Tool. To accomplish this, either click the ASP.NET Configuration icon at the top of the Solution Explorer or click the Website menu's ASP.NET Configuration option. Either way will open a web browser pointed to a page through which the ASP.NET site can be configured. Figure 20.1 shows the ASP.NET Website Administration Tool. To add user account support, click the Security link. This will take you to the Security screen shown in Figure 20.2. From this screen, you can specify the user accounts in your system, what roles for users exist, and the access rules for users. However when I click security I get the following error message; "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." If I test the provider I get this error; "Provider Management""Could not establish a connection to the database.""If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider." I am using MS VWD Express with MS SQL Express. I have run the 'aspnet_regsql' tool on my database which the book fails to mention and verified that the tables were created correctly. I have tried copying the MDF file directly into my 'app_data' directory but this made no difference. I have googled these errors and nothing seems to help. I can connect to the database through a 'SqlDataSource' and have had no trouble with the database in the previous sections of the book. I think it may have something to do with how I setup SQL Express or database permissions, I hope someone can help. Thanks in advance.

I recently installed VS2005 Prof edition and SQLExpress 2005 and have been teaching myself C# using the book
Microsoft Visual C# 2005 step by step.
I have done all the examples including the examples on databases without problems up to chap 27 which is trying to demonstrate adding security to a web site using the ASP.NET Web Site Administration tool.
After opening the tool and clicking on "security" the error message appears.
Unable to connect to SQL server database
As I understand it a database provider AspNetSqlProvider is supposed to create a database called ASPNET.MDF in the App_Data folder of the web site. Needless to say nothing is produced.
I have read various posts and done the following without success.
1 explicitly stated servr.exe as an exception in windows firewall
2 Run Aspnet_regsql at the command prompt. It bombs when I try to put a database name into the list box or even just click on the list box to see what it reveals. ( unfortunately I do not have the exact error but it sugested that it did not have read/write access to something
I do not really understand this . I am just an old fashioned amateur C++ programmer who thought he better get into the new world!
I get the following error trying to use ASP.NET configuration
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.

If I try to run the application it starts up OK but it bombs when you try to put a password in because the database in App_Data has not been created.
hi... i am new to ASP2.0 and i was trying to use the properties associated with the profile class. here what i was trying to do... in "Web.config" <anonymousIdentification enabled="true"/> <profile enabled ="true"> <properties> <add name="p1" allowAnonymous ="true"/> </properties> </profile> in "Default.aspx.cs" protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { Profile.p1 = "Welcome"; LabelResult.Text = Profile.p1; } else{ Profile.p1 = "you'v been here"; LabelResult.Text = Profile.p1; } } but i had the exception ( Unable to connect to SQL Server database) at "App_Code.qzomymsu.0.cs" public virtual string p1 { get { return ((string)(this.GetPropertyValue("p1"))); } set { this.SetPropertyValue("p1", value); } } i know the problem has something to do with providers, and i want to store the values to an XML file.... thank you for helping.
Hi Eevryone: I seem to have corrupted my ASP.net Web Site Administration Tool some how. It worked fine a few days ago, but reloaded SQL Server 2005 Express Edition W Adv Services SP1 yesterday I can not get past the "Unable to connect to SQL Server database" error. I have run the aspnetdb.exe and created both a aspnetdb.mdf and loaded the tables to into a existing mdf. I have checked all the permissions. So any ideas on what I am doing wrong, or can you point me to some documentation on the 'AspNetSqlProvider'
New forum member here, and pretty new to SQL Server. My question is I'm having an impossible time trying to connect MS Access on Computer A to a database running on SQL Server 2k (SP3) on Computer B. Every time I try to create a new ODBC connection on Computer A, I get the dreaded Server Error 17 (SQL Server does not exist or access denied). I have no problems making the ODBC connection on the computer running SQL Server (Computer B).
My connection settings are as follows:
Computer A name = MAINDESKTOP Computer B name (contains SQL Server) = HOMELAPTOP Workgroup name = WORKGROUP
Server Properties:
Name = HOMELAPTOP Authentication = SQL Server and Windows Registered SQL Server Properties = Use SQL Server authentication, and I'm using a login name and password Server Network Utility = TCP/IP network protocol enabled, with default port 1433 Server Client Network Utility = TCP/IP network, default port 1433
Under "Security", I have created a new login using SQL Server Authentication called "bradley", and have assigned a password to the new login. I've noticed that when I open the login properties dialogue, there are always more ***'s in the password field than the number of characters I originally used, but I suspect that's normal. I have assigned a database called "Costume" to "bradley", and have verified that the permission is checked on the Database Access tab for user "bradley".
Under "DatabasesCostume", I have verified that there is a user called "bradley" with the same login name and user name.
No matter what I try, I can't get Computer A to connect to Computer B's SQL Server database. I have no problems with any other types of connections (pinging, internet, file transfers).
I would like to setup the membership and role in web administrator tool, however, under Security section, I got the error message of "Unable to connect to SQL database". I tried to run aspnet_regsql.exe to edit the config(C:WINDOWSMicrosoft.NETFrameworkv2.0.50727>aspnet_regsql.exe), however, it still shows this error message. I am using web developer 2008 and SQL Server 2005. Please advice me how to tackle this problem.
We are unable to connect with Client SQL database server using VPN connection, even we are able connect with their intranet site.
We tried to connect using IP address, but no success. After that tried to ping that server with server name and IP address using command prompt, but got request time out error.
Cannot someone please help me with following problem. I am trying to create a program to update a sql datbase from.NET 2003. I am doing this by using SQL Server Express 5. The problem is, is that when I run the program and click the button to view the table in SQL Express 5 I keep getting an 'System.NullReferenceException' and the table is not shown. When I look at the debug details it says that 'object reference not set to an instance of an object'. Am not sure where am goin wrong as the connection is opened to the local server in SQL Express and I have created a connection object and initialised it to the address fo the datatable in SQL. Please find below the code I am working on which shows the connection string in question and the table being called in button 6 which causes the exception. Any help would be greatly appreciated....thanks

I am unable to connect to express edition by specifying 'TCP/IP' in the Network Protocol option of 'Connection Properties' in managment studio. It gives the following error.
TITLE: Connect to Server ------------------------------
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)

I had already enabled TCP/IP from SQL Server Configuration Manager.
Hello I am able to connect to the server and most of the time I can't connect. It is important to be able to connect so I can manage my mdf - database. To test ... I disable the firework but I still can't connect 90% of the time. Thank you in advance. ~ Peaches ~
Hi, I have VS Pro 2005 and SQL Server Express 2005 installed on an XP Pro machine. When using VS 2005, in the 'Server Explorer' window I can see and attach to two SQL Server databases that I have set-up. But if I attempt to access the same databases from withn the 'Solution Explorer' window I get the following dialog box message,
" Required Component Missing (Dialog box heading)
Connections to SQL Server Files (*.mdf) require SQL Server Express to function properly. Please verify the installation of the component or download from the URL: http://go.microsoft.com/fwlink/?LinkId=49251 "
I have uninstalled and then reinstalled both VS 2005 and SQL Server Express twice but it has helped.
I don't understand why I'm getting this error because all of the server configuration tools and connection utilities seem to work fine but VS say's that SQL Server Express is not installed.
Thanks,
CLN
P.S. I had another application that required MSDE 2000A to be installed. When I removed the other application I also removed MSDE 2000A and that's when the problem began.
