Can't Connect To Sql Server 2005 From My Asp.net Application

Apr 3, 2006

Hi

I can't connect to sql server 2005 from my asp.net web page. I seem to be able to connect to it when i run the application from within visual studio but i can't connect to it when i run the application from IIS.

I am new to sql server 2005 express so please bear with me.

The error message i get is:

 Cannot open database "Vets" requested by the login. The login failed.
Login failed for user 'OSCAR2K4ASPNET'.

I don't know where this user OSCAR2K4ASPNET came from but i looked in sql server 2005 and there he is. In the left hand pane I went to Security and then logins and found oscar2k4asp.net there. I went to the properties for this user and went to User Mappings. There was no tick next to my Vets database so I added one and ran the application from IIS. I also added the user to every single role in the vets database (including dbowner). I also went into the vets database itself and found the oscar/aspnet user and made sure he was added to every role.

I ran the application again. This time i got a lots of different errors. If the page was trying to run a select procedure I got the error user does not have select permission. If the page was running an SP i got the error or user does not execute permission


I have never had this problem before so I don't understand.

Where did this user come from? Was he created automatically when i configured my database for membership and roles? How do i set up this user so he can access the databsae from IIS.

The only way I could get the application to run from IIS was to go to Security - Logins for sql server and add the oscar2k4asp.net user to the sysadmin role.

I find this very strange. Naturally i don't want to leave oscar2k4 in sysadmin.

Please help :) I can't upload my website until i fix this

Thanks, andrea

How To Get A Web Application To Connect To SQL Server 2005 Express

Dec 12, 2006

All,
I'm a newbie here so forgive me if I have missed something completely obvious.
 I have bought a shopping cart script of a well known company (Evolve Merchant 5) and I wish to set it up locally on my development server, I created a virtual directory, set the web application up and get the asp pages to display perfectly. However, in the configuration file (global.asa & web.config) for the application it reguests information to be provided: <add key="DBName" value="Database name" />
<add key="DBServer" value="IP address of server" />
<add key="DBUserName" value="User name" />
<add key="DBPassword" value="password" />
<add key="AltPassword" value="password" />


 What I can't determine is what the SQL Server 2005's IP address is? the pages of this application show when I type http://localhost/catalogue into IE, so I presumed the server address would be the IP of localhost, when typed ping localhost into command promt it gives me 127.0.0.1, but when I enter this into the config file and try to load the application it just hangs and then eventually says:
"Microsoft OLE DB Provider for ODBC Drivers (0x80004005)[Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied./catalogue/global.asa, line 54"
I have created a new database in SQL Express called: merchant509 and restored the tables to it as the manufactures help files state, I created a new login called shop which uses SQl authentication, so as I can provide a password. So the settings should look like this:
  <add key="DBName" value="Database name" />
<add key="DBServer" value="127.0.0.1" />
<add key="DBUserName" value="shop" />
<add key="DBPassword" value="1684" />
<add key="AltPassword" value="1684" />
 
But it doesn't work, does anyone know what i have done wrong?? the SQL server is runnign on the same computer as I am trying to access it from, it is set to accept all forms of comunication i.e. TCP/IP etc.. in the server configuration manager the IP address part of TCP/IP in protocols shows IP1 as 192.168.2.2 active yes enabled yes, and IP2 as 127.0.0.1 active yes and enables yes, I have tried the 192.168.2.2 and this gives the same errors, this is my registed IP on my home network.
 I'm now stumped, I haven't a clue what else I can try, I would be very greatfull if anyone has any ideas.
Regards,
Daniel Coates

Connect To SQL Server 2000 Through An ASP.NET Web Application

Apr 30, 2005

Hi!I am going to connect to "SQL Server 2000" through an "ASP.NET Web Application". My development environment is "Visual Studio .NET 2003". In my "Toolbox" -> "Data", I drag a "SqlConnection" and drop on the page. It would automatically be named "SqlConnection1". In its "Properties" -> "ConnectionString" -> "<New Connection...>", I would enter my Server Name (SAMIEI), select "Use Windows NT Integrated Security" and Select the Database on the Server (Northwind). Then such Connection String would automatically be generated:
"workstation id=SAMIEI;packet size=4096;integrated security=SSPI;data source=SAMIEI;persist security info=False;initial catalog=Northwind"
Now, I may see "SAMIEI.Northwind.dbo" in the "Data Connections" row of "Server Explorer" with its all "Database Diagrams", "Tables", "Views", "Stored Procedures" and "Functions".Please take a look at the following code:
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Try            SqlConnection1.Open()        Catch ex As SqlException            Response.Write(ex.Message)        End Try
    End Sub
It would unexceptedly encounter such error:
"Login failed for user 'NT AUTHORITYNETWORK SERVICE'"
Please tell me the reason. I am much obliged to you for your attention.
Regards!M.Sadegh Samiei

Report Server Direct Connect From ASP.NET Application

May 9, 2007

OK, I am not a programmer, but administrate the Report Server and its security. The .NET programmers want to connect direct to Report Server using WEB.CONFIG settings (see below).



<appSettings>
<add key="ConnectionString" value="Server=bpatlqddwatlqddw01;Database=MP2_NET_STAGE;Integrated Security=False;User ID=MP2_Net;Password=xxxxx;Persist Security Info=false"/>

<add key="LogPath" value="\bpga030wde01wwwroot$MP2_NetLogs"/>
<add key="Url" value="http://bpga030wde01/MP2_Net/" />



What do I need to do to ensure their dynamic reports can run against my Report Server? What kind of rights do I assign the "MP2_Net" (above) login? All of this is outside the IIS-Report Server security environment? Do I assign rights via SQL Mgr? I cannot find any doco on this process.

Can't Connect .Net Application From Windows Server 2003 To Database Server (SQL Server 2000)

Apr 3, 2008

Hi,
I am having a problem connecting my .net applications from the application server to the database server. When I run the application from my windows xp (sp2) box it works fine. When I try to connect via SQL Management Studio to the database server from the application server I get the same error.
Here is the error:
System.Data.SqlClient.SqlException: 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)
 Here is the Environment:
App Server:
Windows Server 2003 Standard Edition
Inside Company's Firewall/ Network
Database Server:
Windows Server 2000 Advanced Edition
SQL Server 2000 SP4
Remote Connections to the Server is checked
Enable Protocols: Named Pipes & TCP/IP
TCP/IP Port: 1402 (I don't know why it isn't the default of 1433)
The db server is sitting out side the Company's firewall (don't ask me why). I can access it fine from inside the firewall on my XP box but not from windows server 2003. There is a web server outside the our network that also connects to the db server with no problem and that is running Windows Server 2003 Web Edition.
I can ping the db server from the app server using the IP address.
I tried using the IP address and the port 1402 in my connection string but that didn't work from any machine (XP and Server).
I imagine the issue is somehow related to the company's firewall but why would it only block Windows Server 2003 and not XP?
What do I tell the network admin to change?
Any help would be appreciated.
Thanks,
Oran

Can't Connect To SQL2000 On Windows 2003 Server Through UDL Of VB6 Component Of ASP Application

Feb 1, 2008

I have problem connecting to a SQL 2000 server that is hosted on a Windows 2003 server. My application uses classic ASP with VB6 components. VB6 components connect to SQL server and return data to ASP application. Everything was working fine when the application and SQL server was hosted on NT machine. Recently we have shifted to Windows 2003 server. Since then we could not establish connection to SQL2000.


I'm using UDL as connection string.
IIS and SQL2000 hosted on the same machine with Windows 2003 OS.
This seems to be a security issue. Earlier I faced this issue for a .net application which I resloved adding a domain account to both SQL server and IIS directory security.
Request your input to solve this problem.

Cannot Connect W/ Java App But Can Connect W/ .Net App - SQL Server Express 2005

Dec 12, 2006

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" />.

These are my values in my Java app web.xml -

<init-param>
<param-name>DBDriver</param-name>
<param-value>com.microsoft.sqlserver.jdbc.SQLServerDriver</param-value>
</init-param>
<init-param>
<param-name>DBURL</param-name> <param-value>jdbc:sqlserver://localhostsqlexpress:1055;databaseName=CORNERS</param-value>
</init-param>
<init-param>
<param-name>DBUser</param-name>
<param-value>sa</param-value>
</init-param>
<init-param>
<param-name>DBPwd</param-name>
<param-value>myPasswd</param-value>
</init-param>.

And yes, the port is 1055 - I checked to find it.

I am using Microsoft SQL Server 2005 JDBC Driver 1.0 (sqljdbc_1.0.809.102).

Does anyone have any idea what is wrong so that the login fails in the Java application but works in the .Net application?

SQLCe Errors When Doing Developing A SQL Mobile Application With Visual Studio 2005 And SQL Server 2005 Tutorial

Feb 26, 2008

I'm attempting to use RDA to synchronize a pocket pc emulator with SQL Server 2005 database by following tutorial http://msdn2.microsoft.com/en-us/library/aa454892.aspx, which uses AdvWorksMobile database that comes with SQL Server 2005.

When get to testing of "To test application features " ( step 4 of the merge replication setup lab ), I am receiving SQLCe Exception errors.

ORIGINALLY, I was able to deploy an application and view the local database on the emulator, but once I clicked "InitSinc" button, I received an error.

"Failure to connect to SQL Server with provided connection information. SQL Server does not" exist, access is denied because the SQL user is not a valid user on the SQL Server, or the password is incorrect.
Found this error listed in Server Agent Errors log http://technet.microsoft.com/en-us/library/ms172357.aspx, but it wasn't very helpful since it doesn't provide any suggestions on fixing the problems.

I am brand new to SQL CE Server , mobile programming and .NET framework in general so please bare with me



All the connections / security settings, etc that were set up were taken from a tutorial so I am not sure what SQLCeServer is complaining about. Reading up on the error on the web didn't help, it all pointed to making sure that the snapshot folder had correct permissions set up. I verified that MACHINENAMEUISR_MACHINENAME guest user had Read rights to the database so I don't think that piece is the problem. Otherwise ,Merge publication has been setup in Microsoft SQL Server Management Studio by following the tutorial.


I am trying to run this sync on my home pc so there should be no issues with any user permissions


I have IIS installed


I did NOT have SQL Server Agent running in management studio at this time


I am trying to run this tutorial on an XP machine, which is my regular home PC so I dont think there are any special networking settings to consider


I am able to hit http://localhost/AdvWorksMobile/sqlcesa30.dll from my pc OK, but when I try to hit it from a cradled emulator ( after replacing "localhost" with "MACHINE_NAME" ), Internet Explorer on the emulator gives me a "Cannot Connect With Current Settings" error message. This part wasn't part of tutorial but decided so not sure if I am supposed to be able to hit it from my emulator..so I am not sure if the fact that I can't hit it is related to the problem.
AFTER STARTING SQL SERVER AGENTin Microsoft SQL Server Management Studio, I killed the application, and after relaunching it, it hits "The Specified table does not exist [Vendor]" error. This time it doesn't even launch first - that is I dont even get to pressing "InitSinc" button. Debugger is showing that this error is hit on the following line in AdvWorksMobile.AddWorksDataSetTableAdapters

int returnValue = this.Adapter.Fill(dataTable);

I am not sure why the errors changed on me after starting SQL Server Agent.
What can I do to fix this connection problem?

Thank you so much for your help!

Can't Connect From Web Application

Oct 21, 2004

Hello,

For my application, I need to consult a database located on a server on the local network. The application is located on my pc. I use the connection string
Code:

"Integrated Security = SSPI;database=dbName;data source=serverName"

(I program in C# and connect with ADO.NET)

When I compile my project as a windows application, this works fine. But when I compile as a web application in ASP.NET and try the same connection, it won't connect. How can this be solved?

May 7, 2002

Hi guys.

We have an external webserver(server1 on domain1) is a DMZ, and sql server7(server2 on domain2) inside the firewall.

Domain1 trusts domain2 but domain2 does not trust domain1.

Our firewall hosting by outside vendor and they told me they already opened up the port 1433 for server2.

I put a small asp.net application on server1(this application works fine in intranet. 2000 server,iis5,virtue directory, and .net frameword were well installed and configured), and I got S'QL server does not exist or login fail error'.

Any idea about that? And how to test the port was opened?

Any input appreciated.....

Visual Studio 2005 Unable To Connect To SQL Server Express 2005

May 26, 2008

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.

How To Call SQL Server 2005 From ASP.NET Application?

Apr 17, 2008

I am trying to call a view that is already in SQL Server 2005 from my ASP.NET 2.0 application.  I get the following error message:
 The request for procedure 'vwMyView failed because 'vwMyView' is a view object.
 I thought I could call a view the same way that I call a stored procedure but I guess I was wrong.  How can I fix this?
 Here is some sample code too:
Dim Results As DataSetDim Cmd As IDbCommand
Dim Adapter As IDbDataAdapter Results = New DataSet
Cmd = DB.CreateCommandCmd.CommandText = "vwMyView"
Cmd.CommandType = CommandType.StoredProcedure
Adapter = DataSource.CreateDataAdapter
Adapter.SelectCommand = Cmd
DB.Open()
Cmd.Connection = DB
Adapter.Fill(Results)
Cmd.Dispose()
DB.Close()
Return Results

Problem In VB6 Application With SQL Server 2005

Apr 2, 2006

I have got a VB6 application where I update local SQL server table from MS Access table with code like that:

----------------------------------------------------------------------------------------------------------------

Dim rst As ADODB.Recordset
Set rst = New ADODB.Recordset
rst.Open "SELECT * FROM Table1 WHERE [Fld1]=" & v1, Cn, adOpenKeyset, adLockOptimistic
'check if exist if not exist create new
If rst.EOF Then
rst.AddNew
rst("Fld1") = v1
rst("Fld2") = v2
rst.Update
End If

rst.Close
----------------------------------------------------------------------------------------------------------------

On rst.Update I have got an error message that the server has to be added to syservers as linked with stored procedure sp_addlinked srever. Why?

Anyhow I executed the stored procedure then I've got error message 16933, "The cursor does not include the table being modified or the table is not updatable through the cursor."

I had to rewrite the code to "INSERT INTO (Fld1, Fld2..." and it works.

Is something wrong in SQL Server 2005 installation or any other reason?

Please help.

Connect A Report To An Application Database

Aug 3, 2006

I added a database named appdata to the app_data folder to hold temporary application data.  I want to show this data in a report.  I created a dataset and an object to select the data.  I then created an report.fdlc and a report.aspx with a ReportViewer on it pointing to the dataset object.  If I right click on the report.aspx and View in Browser, it work perfectly.  But when I upload it to the server I get and browse to it I get (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified).  The server does allow remote connections.  So I am thinking it's my connection string of the fact that the server doesn't have Sql Server Express.?
Here's my connection string.  What am I missing here?
<add name="appdataConnectionString"
connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|appdata.mdf;Integrated Security=True;User Instance=True"
providerName="System.Data.SqlClient" />

Can't Connect To Sql Server 2005 Database Using Vb 2005 Express

Nov 21, 2006

I've used Sql Server 2000 and Visual Studio 2003 for a few years. I've started a new position and they have access to Sql Server 2005 Standard and Visual Basic 2005 Express which I'd like to use for a new project. So I installed Sql Server 2005 and then VB 2005 Express on my workstation. I didn't choose the Sql Server option for VB Express because I already had Sql Server 2005 Standard installed with a simple database created. I created a simple vb project that justs connects to the database but I get the following error.


Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0000, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I looked at permissions in the database and it looks ok. I'm the db owner and I'm using Windows Auth. My connection string is

"Data Source=MySystem;initial catalog=AdventureWorks;integrated security=true;"

I thought I'd look at the starter kit to get some ideas about what the problem is, but when I started the movie starter kit project, it was upset that I didn't have Sql Server 2005 EXPRESS installed. Yea, but I do have Sql Server 2005 Standard installed.
Any help will be greatly appreciated. Thanks.

Application Insist Open SQL Server 2005 While The Host Still With SQL Server 2000

Mar 12, 2007

I don't know why my application on the internet try to access the SQL Server 2005, when the host still having the 2000 edition. I put the following connection string: 
        Data Source=##DBSERVER##;Initial Catalog=##DBNAME##;User ID=##DBUSER##;Password=##DBPASSWORD##;       
 
Isn’t everything fine with that? I created the table by host but dosen’t work. I’m wondering if can I conect straight with Data Base, without register in the server, like with mdb?
 
This is the error that I’m getting.
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)

MSDTC - Remote Accessing SQL Server 2005 From A Desktop Application - Windows 2003 Server

Dec 6, 2007

Hi,

I am developing a windows application that needs to communicate with a remote SQL server 2005 database. Server allows remote connections and MSDTC service also running. Do I need to run MSDTC service on the client machine where I use desktop application ? any ideas ? It's throwing some error like
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.

But my SQL Server allows remote connection, and I am able to do a select statement.
But when I insert/update anything, it's throwing this error. I guess some problem with MSDCT. Anybody have any idea ?

SQL Server 2005 - Windows Application And Website

May 25, 2007

Hi there,
I have a question which I put the company that host my website but I didnt get a conclusive answer. Maybe someone here will be able to advise or help me with my situation.
I want to build a database that I will run on my local server and the front end of this will be run using a windows application. I have a website which I run the database on the remote server. What I would like to do is to be able to synchronize certain tables between the two databases (such as updating products table, or orders table). I am using sql server 2005 and I am using the sql server management studio to access my database on the remote server. I did notice there is a synchronzie button. I also came across some 3rd party tools. Not sure if that is the way to go.
If anyone as done this before or can give me any suggestions, I would be delighted.
Thanks
 Anthony

SQL Server 2005 Application Role's Problem

Oct 8, 2007



Hi all.

I have developed a VB6 program which will activate an Application Role to UPDATE and INSERT some tables in SQL Server 2005.

My program will login with a username, say USER and then run with the rights of the Application Role which will SELECT, UPDATE and INSERT the following tables:
1) Table A
2) Table B
3) Table C

The USER login is a restricted user which has only SELECT permission to Table A, B and C.

I encounter a problem in which my program can only UPDATE table B and table C but Table A. I have double checked the settings of Table A, Table B and Table C. Theirs are all same. Fyi, the column which can't be updated is of type "datetime".

Once i grant USER login UPDATE permission to Table A, my program works perfectly in which it can UPDATE all the tables including Table A.

I have tried for almost 2 days but am still clueless. Any ideas?

Thank you so much.

Accessing SQL Server 2005 From C# Using Multithreaded Application

Apr 18, 2007

I have a C# program that access SQL Server 2005. The program have 4 threads that performs the same method and are used only to improve performance of the system
The C# accesses the SQL Server using OleDbConnection and

OleDbCommand classes. Sometimes (very rare) I get exception to method ExecuteNonQuery() with message: "Table does not exist.".
The command text for the query is a constant string in the format: "insert into my_table€¦".
Can any one tell me what could be the problem?
