No Access From Application To SQL Server 2000
May 19, 2006
I have installed the SQL Server 2000 and its up running.
I can connect to the database direct as administrator, but my test application(asp.net 2.0) returns an exception.
SqlConnection sqlConn = new SqlConnection("data source=10.61.90.24;initial catalog=testdb;persist security info=False;user id=sa;pwd=data;Type System Version=SQL Server 2000;");
sqlConn.Open();
I receive this exception:
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)
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

First off, sorry if my cross posting offends anyone. I'm posting thisin Access and SQL Server groups - not sure which one is appropriate.I have a relatively simple ASP.NET/VB.NET application that is nowhitting an Access 2000 database over an intranet. We have to migratethe database to SQL Server 7. My experience with ASP.NET is prettylimited and my experience with SQL Server is nonexistent.We have an MSDN subscription, so I went to the downloads section to getSQL Server 7. Guess what? SQL Server 6.5 is available, as is 2000 and2005, but no SQL Server 7. So my first question is, does anyone know ifit is available for MSDN subscribers?The next question is, does anyone know of a good resource that explainshow to make the transition from Access 2000 to SQL Server 7? I know thedata has to be migrated and the connection between the application andthe database modified, but am really not sure exactly what to first andthe correct way to go about it. The application is a simple productconfigurator. There's not a lot of data and it's not a very complexdatabase.Thanks in advance. If you'd like, please copy responses tolcifers(AT)yahoo.com (AT) = @TIA.Cheers.- Luther

Hello all, We have a SQL database that uses a MS Access projectfront-end, which I am now creating an ASP.Net application for (And am completely new to so may be missing some foundation concepts). With the Access project I added Active Directory groups to the database to use for permissions, logins, etc. For the ASP app I have it set to use Forms authentication with Active Directory (ActiveDirectoryMembershipProvider). I can login to the app with the AD usernames/passwords but the connection from ASP.Net to SQL is using the ASP User. Is there a way to provide the authentication from the ActiveDirectoryMembership through to the SQL server, so the user: bobuser would be authenticated to SQL instead of ASPNETUSER?Or do I need to have the ASP.net app handle the permissions of which SP's a user can execute?Any help or suggestions are appreciated.Thanks,Jamie.

Hi,
I have recently transfered data from MS Access to MS SQL Server 2000 and created user interface in MS Access Project (ADP). Now I need to secure the data on server and want to access it ONLY through interface I created in MS Access. Every user has to log in the application (user id and password). Users may have the same access rights to the server (so maybe just one account or whatever I need for all of them). Can anyone advice me how to set it up? To access sql server from MS Access I am using ADO.
Thank you.

Hi all
Certain people in our company want to use Crystal Reports for data-processing. Problem is we want them to NOT be able to access data in databases within the live server.
Given that we use trusted connection to validate all kind of data-access, I am wondering if there is a way so that (via NT administration or via some SQL Server security features)
the live-server can refuse any connection request from the Crystal Reports application. At the moment the same group of people are allowed access to database (and should remain to be so) on this "live" server via some other applications (e.g. Microsoft Access).
Any advice is welcomed.

Hi there,I have written an application which uses MS Access for it's database engine.Due to the large size which the database has become I have decided that itwould be sensible to use SQL Server with the application instead.I am an extreme SQL Server newbie so I am not really sure what I'm doingyet! I have successfully downloaded and installed the MS SQLDE 2000 andservice pack 3.What do I need to do next? Ideally I would like to convert the existingAccess database to MS SQL Server format. Also I would like to know if it ispossible to create an SQL Server database from scratch using a guienvironment similar to Access and if so which software (preferably free) doI need to achieve this?Many thanks,Clive.

I have a ASP.NET time sheet management application I designed - today I put it live on the webserver and recreated the database on my SQL 2000 server. When I attempt to view, all of the pages where I query the database I catch the error "SQL Server does not exist or access denied".
The concerning part of this is that I have tested the live database from my development PC (remote - offsite) and it works fine. This shows that the database that I brought over is intact and the user has the appropriate permissions. The only thing that I changed in the application when I copied it to the server was the connection string server name to reflect the location change.
The setup is as follows:
Development PC on a broadband connection running Windows 2003 server enterprise, SQL Server 2000 SP3a, Visual Studio 2003 Enterprise.
Web/Database/Email server running Windows 2003 Standard, SQL Server 2000 SP3a, Exchange 2003, Active Directory, DNS etc.
When I run the application on the Web server from a browser with local names ie. http:\SERVER1application I get the "SQL Server does not exist or access denied" errors. When I try to connect to the application on the web server from my development PC i get the same problem.
When I changed the connection string on my development PC to the webserver/dbserver it runs fine.
I don't understand how a local proccess is having difficulty authenticating to the database when I can access it remotely just fine.
Anyone have any suggestions?

My database knowledge are with MySql and Oracle, but recently I was asked to evaluate the migration of an existing (and maybe more) from ms access to sql server. My question is simple, if all of the sql are hard coded into the code ... how well this sql will work, I mean is the sql between access and sql server are plug'n'play ? However in any case, I always rewiew all of the sql.

Hi guys
I'm writing a C# application which connects to a local SQL database for data access. The application connects to SQL Server through windows authentication, but opens up the port and sqlbrowser to others on the network wanting to access the database through SQL Server authentication, and also allows remote users to connect to this server remotely if they have the login and password (and because the port is already open)
I understand this is not secure and open to attack, and am unsure of how to secure these processes without blocking these three types of access, from A.) the local user, B.) the network user and C.) the remote user across the net.
Have researched this a fair bit, but get somewhat lost amongst all the jargon.

All:
I am writing an Internet/Extranet based (ASP.Net 2.0) web application that uses SQL server 2005 as the database. I am using forms authentication on my web application. I am also storing the connection string to SQL server in my web config file. The conn string is encrypted using DPAPI with entropy. I currently have created a SQL login account on my SQL server for use by the web application. This is the user ID I am using in my conn string. The reason for this is because all persons using the application will NOT have a windows login.
Here is my question: The login I created currently has defaulted to the "dbo" role and therefore has "dbo" rights to the database. I want to setup up this login account so that all it can do is execute stored procedures. I dont want this SQL login to be able to do anything else. In my application I am using stored procedures for ALL data access functions, via a data access layer in my application. Can someone guide me step by step as to how to setup this type of access for this SQL login.
Thanks,
Blue.

Hi,
first time poster/newbie here.
I've
got a football (soccer for the yanks!) predictions league website that
is driven by and Access database. It basically calculates points
scored for a user getting certain predictions correct. This is the URL:
http://www.pool-predictions.co.uk/home/index.asp
There
are two sections of the site however that have almost ground to halt
now that more users have registered throught the season. The players
section and league table section have gone progressively slower to load
throughout the year and almost taking 2 minutes to load.
http://www.pool-predictions.co.uk/home/players.asp?tab=a_d
http://www.pool-predictions.co.uk/home/table.asp
All
the calculations are performed in the Access database Ive written and
there are Access SQL queries to get the data out.
My
question is, is how can I speed the bloody thing up! ! Somone has
alos suggested to me that I use stored procedures and SQL Server to
speed things up? Ive never used SQL Server before so I am bit scared
about using it (Im only a hobbyist), and I dont even know what a SP is
or does. How easy will it be upgrading the whole thing to SQL Server
and will it be worth the hassle, bearing in mind I expect my userbase
to keep growing? Do SP help speed things up significantly? Would
appreciate some advice!
Thanks in advance,
John.

We have applications connected to SQL using windows authentication. While having connection with Application user can also access to Database instance on the same time as well. We need to limit the access of user outside application.

Hi Everyone,
I have a software solution that consists of two separate applications that share a SQL Server Express database on a single computer. Everything is working great, except when both of the applications want to access the database at the same time. All I can find is information on configuring multi-user access in a distributed system. I'd appreciate any information on configuring multi-application access on a single computer.
Thanks,
Mike

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

Hi guys,I'm not sure if I'm just bad at googling but I can't seem to find a way to set an ASP.NET 2.0 web application to connect to SQL Server 2005 using the current client's user credentials. My web application is using Integrated Windows Authentication so its Page.User.Identity is set to a DOMAINusername value... I want to pass that to my connectionstring or have my connections pick up the identity automatically and use that Identity when accessing the db server.Oh and another thing, my IIS Application Pool is using a specific Identity itself, so I don't know if that might affect the above.Hope someone could help.

I have to create a query that will be returning the users and the application modules they have access for. Along with the list of users and modules the query should also return if any module is not accessible for that user.
The 'ApplicationUsers' table is like this:
CREATE TABLE #ApplicationUsers
(
userId INT,
UserName VARCHAR(50)
)
INSERT INTO #ApplicationUsers VALUES
(1, 'Daniel'), (2,'Martin'), (3, 'Brandon'), (4, 'Doug')The 'ApplicationModule' table is like this:
[Code] .....
I used pivot query but there are a couple of limitations in it(may be I am making mistakes in it). First, the pivot columns are static whereas I need dynamic column names(Application Modules). Second, I need to include all the users with all the modules with access or without access that I am unable to achieve.

Here is my situation: I am creating a database driven ASP.Net web application that will be used over the internet. My ASP.Net application connects to my SQL server 2005 database/server by using a SQL server login. I am using the DPAPI API to encrypt my connection stings with a hidden entropy value for extra security. I am using the SQL login for obvious reasons, as my users will not have a windows login.
What I am trying to do: I want to limit this SQL login account to be able to just run/execute stored procedures and NOT access the tables or views directly. In my ASP.Net application I am using the MS applications data block, and I am using stored procedures for every single database access action. There is no inline SQL being executed from my web application.
What I have tried so far:
I created a new schema and made the above SQL login account owner of this schema. I then granted "Execute" permissions to the SQL login and DENY permissions to all other permissions.
I created an database role with "Execute" only permissions and DENY permissions to all other permissions.
What Happened: In BOTH of the above scenarios I tested a direct SQL statement against one of my tables, from my ASP.Net application and I was able retrieve data back, NOT GOOD, exactly what I am trying to STOP.
If someone could give me (Step-by-Step) guide on how to setup the situation I am looking for, I would be very grateful!
Thanks to all that help!

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

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.

I've created a small company database where the tables reside in a SQLServer database. I'm using Access 2000 forms for a front end.I've got a System DSN set-up to SQL Server and am using links withinAccess 2000 to get to the SQL Server tables.My forms worked fine until I made a few minor changes to the databaseschema on SQL Server (e.g. added a foreign key, or added a column).After that, all the links break - I click on a table link and get anerror msg like "invalid object name."Deleting the links after a schema change and re-adding the links seemedto fix the problem. The forms I'd already created seemed to work fineafter re-creating the links.But then I got more advanced with my forms. I have it set up so thatfor certain entry fields, the combobox gets populated with values froma table (the description appears in the drop-down and the correspondingprimary key value gets populated in the table). I created a number offorms using this technique, entered data, and everything worked fine.Made a small schema change and it broke everything -- not the actualtable links, but the functionality for the drop-downs. My values nolonger appeared, and this was true for forms that accessed tables whoseschemas did not change.This is driving me nuts. Is there any way to keep my forms frombreaking each time I make a small schema change?Thanks.- Dana

I am developing an application that uses Access database (mdb file) to store the user data. The user of this application is not interested in the database file (to view in MS Access Environment). Does the user machine requires MS Access installation to run my application or just some couple of dlls (OleDB driver, Access DB Engine,..) should be enough to run my application?
