Aspnetdb Connection Could Not Establish But Database Correctly Created.

Sep 2, 2007

I installed netframework 2.0 Visual Web developer and MSSQL 2005 express edition with SQL Server management express.
I have got this configuration: 2*256 mb ram Intel Pentium 3.2Ghz Windows XP HUN SP2 latest version.
server name: localhostSQLEXPRESS
Authentication: Windows Authentication

I run aspnet_regsql.exe and the setup wizard created aspnetdb see here, Microsoft sql server management studio can see the database:



But! When I run to the asp.net web application administration tool in Provider Configuration and choose
AspNetSqlProvider only 1
then I click Select a single provider for all site management data link -> then test

The Tool write this:
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.

Asp.net SQL Server 2005 Setup. Unable To Establish Database Connection Correctly.

Feb 20, 2008

I am setting up a web server and I'm having some issues with database connections.  I am running Windows Server 2k3 and SQL Server 2005.  The error I get is when I attempt to connect to the database, it's the following:
     Cannot open database "dbReseacher" requested by the login. The login failed.     Login failed for user 'userRes'.
The following is my connection string:
    <add name="RESEARCHER" connectionString="Data Source={Sql Server}; Server=THRALL2; Database=dbReseacher; Uid=userRes; Pwd=password;"/>
In SQL Server Management Studio, the user userRes is listed under Security -> Logins, but it is not listed under Database -> dbResearcher -> Security -> Users.  Originally it was listed under both and this didn't solve the problem. 
Please let me know if you any ideas or questions that I can answer.  Thanks a lot.

Not Able To Establish A Connection To My Database In C#.

May 2, 2007

Could someone help me out? I am stuck and I don't have $245.00 to pay for Microsoft Technical phone support.
Basically I am trying to establish a connection to my database using C#. When I try to connect I can step into the line of code, but an exception is thrown.
Error message in the debugger:
ServerVersion = 'myConnection.ServerVersion' threw an exception of type 'System.InvalidOperationException'
 
C# code:
SqlConnection myConnection = new SqlConnection("Data Source=BVCOMPUTER;Initial Catalog=TheMarket;User ID =bill;Password=celebrate4ever");
When the above line of code is executed, then In the IDE debugger when I do a watch on myConnection, there is a tree node labeled "ServerVersion" The following messageis displayed there:
Also there appears to be a property of "ServerVersion"  named "base".The error message stored there is the following: base {"Invalid operation. The connection is closed."} System.SystemException {System.InvalidOperationException}
----------------------------------------------------
Note that I can drag and drop a grid control on my web form and point to the database I want to connect to. But for some reason when I manually try to connect, I am not able to.

Could Not Establish Connection To Database

May 12, 2007

I am having a great deal of difficulty connecting my version of visual web developer 2005 express to the AspNetSqlProvider as stated in the tutorials online at the web developer center. I keep getting the error below.



"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. "



When I run the utility I still get a connection error using the hostname of my computer and windows authentication.



The setup failed message is as below also:-

The AspNetSqlProvider Could Not Establish A Connection To The Database.

Aug 8, 2007

Hi!
When I'm going to the Web Site Administration Tool at the Provider tab I click to test the AspNetSqlProvider, but it says
"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 have enabled the TCP/IP and name pipes at the SQL Server, and I have created a database using the aspnet_regsql and when I'm going to test the provider it always says me that "Could not establish a connection to the database..."
Can anybody help me?
Thanks

Error 'Could Establish Connection To The Database '

Mar 16, 2006

Hi,
I encounter few errors when I try to create a login page using tool in Microsoft Visual Studio 2005, please refer to below :



'-------------------------------------------------------------------------------------
 I create a Login screen from Toolbox.
 When I try to configure the setting for Provider Configuration in the ASP.NET Website Administration Tool using Select a single provider for all site management data or Select a different provider for each feature (advanced) options, the error ‘Could not establish a connection to the database’ appear.


I have tried to run aspnet_regsql to configure the server and database and return to this tool to configure the Provider configuration but the same error ‘Could not establish a connection to the database.’ appear.
When I click the Security Configuration link in ASP.NET Configuration, the error as shown below appear :
'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 below button to be redirected to a page where you can choose a new data store.
The following message may help in diagnosing the problem: An error has occured while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact under the default settings SQL Server does not allow remote connections.(provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)'
When I try to choose Data Store in the Security Configuration screen(Figure 4),  the same error(‘Could not establish a connection to the database’) appear.
 '----------------------------------------------------------------
 
I also have tried to configure the SQL Server Surface Area Configuration but the same error still appear….
Is there any other configuration I need to set before I can create this login page?
 Any advices or help is much appreciate.
 
Thank you.
 
 
Regards,
Vicky

How To Establish Connection Between SQL Server Database && VWD 2005

Mar 24, 2007

I just got a shared hosting plan with godaddy (economy plan) ...
I wrote a simple application with a database. it works fine on my local PC.
I tried to upload my files to the server, but i couldn't get database file on godaddy's server. I did a little research and found out they dont allow uploading database files to their server nor they allow remote access either.
so I logged in to my account and found a database links and I created one (SQL Server)




Host Name
whsql-v44.prod.mesa4.secureserver.net



Database Name
DB_43434



Database Version
2000



Description
maindb
I then logged in to the database and created a new table .. but now I dont know how to make a connection between this database and my application on my pc.
I later found that I must modify my web.config file for the database to work. http://help.godaddy.com/article.php?article_id=689&topic_id=216&prog_id=GoDaddy&isc=

<connectionStrings><add name="Personal" connectionString="Server=whsql-v04.prod.mesa1.secureserver.net;Database=DB_675;User ID=user_id;Password=password;Trusted_Connection=False" providerName="System.Data.SqlClient" /><remove name="LocalSqlServer"/><add name="LocalSqlServer" connectionString="Server=whsql-v04.prod.mesa1.secureserver.net;Database=DB_675;User ID=user_id;Password=password;Trusted_Connection=False" providerName="System.Data.SqlClient" /></connectionStrings>
Now- I am new to web developing, but I do understand that this code is not enough to create the connection to the database. I researched alot but I cant get further.
 What code/ settings/ steps do I need to do to get my gridview and other database items connect to the database on godaddy's server ?
any help would be greatly appreciated...

Need To Establish A Remote Connection To An Sql Database On A Local Server (same Domain)

Feb 16, 2007

Hi, I have been creating a web store, which we will be hosting on our Windows Server 2003 system.  I am also writing a windows application that will be running on our client systems on the same network/domain.  I have no need to allow internet access to the database, just within our domain.  Pretty much the windows application will be running and whenever a customer places an order, the program will automatically pop-up the needed information for our credit card processing, and shipping department.  So far I have been able to establish a connection to our server by creating a data connection under the server explorer.  However, it does not list any databases whatsoever, the web site has been published using Visual Studio 2005 Professional on the server, and is in 100% working order.  I have searched and haven't found anything concrete on this, i'm sure its just something simple that im missing.  It appears that the server is definetely connected to the database (since the website is fully functional), but it is not listing the information for other systems to access it.  If anyone has any ideas, please let me know.  Thank you

I have the following query in an ExecuteSQL Task:

Moved Aspnetdb To SQL Server - What Permissions Do I Need To Give The ASP IIS Service Account For That? (Getting: Cannot Open Database Aspnetdb Requested By The Login. The Login Failed.)

May 12, 2008

I am getting the error:
Cannot open database "aspnetdb" requested by the login. The login failed.
When I browse to my ASP.NET 3.5 LINQ web application on the IIS 6.0 server on Server 2003.
I imagine this is because while I granted SQL Server 2005 login and permissions to my database that the application stores its data in, I did NOT grant any rights to the service account the IIS Application Pool uses for its identity to the aspnetdb database on SQL Server which is where all my roles information is stored at.
My question is what are the MINIMUM permissions needed for this database so it can perform its roles related functions?
I'm using Windows Authentications with the SQL Role provider for authorization.
 
Thank you.
 
 
EDIT: I think I only need to open the aspnetdb database and add my login to the aspnet_Roles_FullAccess role.  Is that correct?

How To Establish Connection To SQL Server?

Mar 31, 2004

in the Quick start, it used connection string ("server=(local)NetSDK;database=pubs;Trusted_Connection=yes") to connect to the SQL db.

Now my working environment is, Im working on my client running .NET Framework as a webserver, and the SQL Server is on another PC as a db server (IP: xxx.xxx.xx.xx, user: webuser, pwd: webuser).

1st Question:
how do I build my connection string for this??
I tried following but no luck:
"user id=webuser;password=webuser;Initial Catalog=Bei;Data Source=xxx.xxx.xx.xx;Integrated Security=SSPI;";


2nd Question:
I just happened to see that ODBC is no more recommended in ASP.NET ?? if that's the case what is the new way to connect to DB ?? by using connection string or what ??


Thanks heaps!

I can't register any other new servers, even ones in my workgroup. I'm connecting using named pipes, but have also tried using TCP/IP setting it up using Client Network Utility.

When i log on to another machine using my network login - I can connect.

There have been no problems connecting in the past and I haven't changed anything on my machine - any ideas???

Client Unable To Establish Connection

Hi Guys.

We have a clustered server. When i create DTS packages in the secondary server I can get all the connection. But when i create DTS package that has connection to other servers. I am getting the follwing error. So my jobs that runs the DTS packages are failing.

Error Source: Microsoft OLE DB Provider for sql server

Error Description: Client Unable to establish connection.
Connectionopen(createfile())

I deleted all the entries in the Client network utility and recreated with ip addresses and TCP/IP protocol.

Added all the ip addresses to Lmhosts and host files.

Check the Server Network Utility.

I dont have a clue now.

Anyhelp are well appreciated.

-Thanks

Long Time To Establish A Connection

Jul 23, 2005

When I login using QA to my SQL Server database, it takes 15-20 secondsto establish a connection and open a query window. Drilling into adatabase via Enterprise Manager is similar. Once the connection isestablished, the server runs plenty fast however.Can someone tell me why it could take a long time for a connection tobe established?This behavior occurs when I am local on the box.Thanks,John

Unable To Establish Connection With The Microsoft SQL Server 2005

Jun 19, 2008

Hi,   I am using Microsoft Visual Web Developer 2008 Express Edition. I wanted to add a database to the Project. When i add it, it says "An error occured while extablishing an 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). Please let me know what is the cause of this error. Initially i downloaded Microsoft Adventure works database and saved the file as .mdf and tried to access it through the data grid. I got the same error message as above. I changed the settings in SQl server to enable remote access and also changed firewall settings to allow SQL server exe files. Then i uninstalled works db and now have disabled remote access and still have the firewall settings to allow SQL server on. Thanks,Vidhya

The Underlying Connection Was Closed: Could Not Establish Secure Channel For SSL/TLS.

Nov 20, 2007



Help.

Today while trying to get the Windows NT security working i upgraded my reporting services IIS server to a domain controller and it screwed up all of my settings. First it changed password for ASPNET user and so I reinstalled .net framework.

Now i get the



The underlying connection was closed: Could not establish secure channel for SSL/TLS.


error message.

I do not want to use an SSL certificate for I do not have one right now. How can I configure my SQL Server 2000 Reporting services to not use SSL. I see they added something to SQL Reporting Services 2005 in the configuration tools but I cant find out how to modify the config files with SQL 2000 RS to eliminate the SSL.

Please help, my company is down waiting for me to get this back up.

Thanks a ton,

deep

Get New Database Created Then Running Script To Created Tables / Relationships

Jun 29, 2015

trying to get a new database created then running a script to created the tables, relationships, indexes and insert default data. All this I'm making happen during the installation of my Windows application. I'm installing SQL 2012 Express as a prerequisite of my application and then opening a connection to that installed SQL Server using Windows Authentication. 

E.g.: Data Source=ComputerNameSQLEXPRESS;Initial Catalog=master;Integrated Security=SSPI; Then I run a query from my code to create the database eg: "CREATE DATABASE [MyDatabaseName]".

From this point I run a script using a Batch file containing "SQLCMD....... Myscriptname.sql". In my script I have my tables being created using "Use [MyDatabaseName]   Go   CREATE TABLE [dbo].[MyTableName] .....". So question is, should I have [dbo]. as part of my Create Table T-SQL commands? Can I remove "[dbo]."? Who would be the owner of the database? If I can remove the [dbo]., should I also remove dbo. from any query string from within my code?

The Underlying Connection Was Closed: Could Not Establish Trust Relationship With Remote Server.

Sep 21, 2007


I am trying to setup SQL Server 2000 Reporting services with an SSL connection. The SQL Server (Windows Server 2003 SP2 Standard) and Reporting Server (Windows Server 2003 R2 SP2 Standard) are on separate machines. I have tried setting up Certificates from both and Stand-Alone and Enterprise CA. I have tried several combinations of the Issue To name (server | server.company | server.company.local) I have modified the rsWebApplication.config and rsReportServer.config to match the certificate€™s Issue to exactly. I have tried installs with both Domain Accounts and NT AUTHORITYSYSTEM logins. I have managed to get https://server/ReportServer to work but I have had no luck with the report manager https://server/reports. How do I fix this error?


Thankyou

The Underlying Connection Was Closed: Could Not Establish Trust Relationship For The SSL/TLS Secure Channel

Nov 17, 2006

I'm using SQL Server 2005 (SP1) Reporting Services on Windows Server 2003 SP1. I access the report server from Internet using SSL, but the server is not exposed directly to the internet. It is behind a firewall, where the required ssl port is setup and is working fine.

In my Reporting Server, the /ReportServer folder works perfect and I can navigate and view all reports. It is the /Reports folder the one that does not work fine. I can enter the /Reports folder, and can list all the reports. But, when I select one of the reports, and it starts rendering, I get the error message:

"The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. The remote certificate is invalid according to the validation procedure."

How can I fix this?

Thanks,

Julio

Accessing MSDB Shows Client Unable To Establish Connection... Encryption Not Supported Error

Nov 23, 2006

Hi,

I currently have SQL2005 Std, using 2 separate domain accounts for both SQL server and SQL agent. When accessing the MSDB stored packages folder from mgmt studio, I get the following error:

Client unable to establish connection.
Encryption not supported on SQL server.

I did google for this error, but have tried all suggestions, including updating the MsDtsSvr.ini.xml file with the servername. I am using a default instance.

Also, I am only able to access the MSDB folder if I set the SQL service account to the local admin account. I have also set the SQL service account to be part of the local admins group, but without any luck.

TIA.

Aspnetdb Connection String

Jul 9, 2006

Hello,  I'm getting up to speed with VS2005 and use SQL Server 2005.  I'm using the login control in a test web app.  When I run the app I get this error:
Cannot open database "aspnetdb" requested by the login. The login failed.Login failed for user 'UserIDASPNET'.
The connection string I'm using is:
data source=localhost;Integrated Security=SSPI;Initial Catalog=aspnetdb;
The AspNetSqlProvider in the web administration tool connects to the database.
My question is, Is this a connection string issue, and user ID issue, a rights issue or is it something else?
Thanks,
Gaikhe

ASPNETDB Connection Problems - Please Please Help!

Mar 29, 2006

Hi I am working on my final year project and after over coming one major problem with sql server I have encountered another.

It feels as if I have tried everthing to solve it but cant get my head around it. I really do not have much time left to finish my project and am very worried in case I cant get the app / db fixed in time.

The problem started when I was showing my friend the website over the internet. There was a space in the address / folder name so I decided to create a new folder and copy the contents of the code from the old folder to the new one. This included the app_data directory that holds the databases for my system.

After setting up a virtual directory in IIS v 5.1 i ran the website only to be confronted with not being able to log in.

I have three connections ..... aspnetdb.mdf, x.mdf, y.mdf.

x.mdf and y.mdf are both being read from ok when I run the app but it doesnt seem to be reading from the aspnetdb.mdf database.

I have tried all sorts of things and had all sorts of error messages including:

cant write to database as its read only

cant access database because its already there.

It seems to me that there is more than one aspnetdb.mdf file attached therefore the app is reading from the new one and not the one i want it to.

I will paste the web.config file below. Please note that before i copied and pasted code to a different location this web.config was working fine. Also note that when I hit ctrl+alt+del it shows up 3 sqlservr processes -

sqlServr.exe - Network Service
sqlServr.exe - Rodney (my log on name)
sqlServr.exe - ASPNET

<connectionStrings>

<add name="Classes" connectionString="Data Source=.SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|Classes.mdf"

providerName="System.Data.SqlClient" />

<add name="Iftams" connectionString="Data Source=.SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|Iftams.mdf"

providerName="System.Data.SqlClient" />

<remove name="UsersDB" />

<add name="UsersDB" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|ASPNETDB.mdf;Integrated Security=True;User Instance=True"

providerName="System.Data.SqlClient" />

</connectionStrings>

I have tried reinstalling sqlserver, creating a new website from the vs2005 ide and also creating a virtual directory first and then copying files to it.

I have also tried attaching to management studio, changing user settings etc

I really dont know what to do next. My head is fried. Please help.

I would really appreciate your help on this one.

Regards in hope

Rodney
