Security :: Failed To Connect Sql Server 2008 On The Same PC?
Mar 12, 2010
In the VS2008, everything works just fine. But after deploy app to the IIS7, tried to access SQL Server 2008 on the same PC, I got the following errors:
[SqlException (0x80131904): Login failed for user 'NT AUTHORITYNETWORK SERVICE'.]
System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) +4846887
System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) +194
Upgraded from SQL Server 2005 to 2008, now when my app tries to execute If Membership.GetUser() Is Nothing Then it says A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified). Confused as to whether this is a problem connecting to ASPNETDB.MDF or my DB in general so I went into Server Explorer and created a connection to my DB, tested successfully, then grabbed the connection string. It matches what's in my web.config so I think the problem is ASPNETDB.MDF only works with SQL Server 2005 Express. If this is true, what do I need to do to use this app with SQL 2008? Should I just delete ASPNETDB.MDF?
I have asp.net application, using LINQ to connecto to SQL Server 2008 R2 databse. My connection string: Data Source=[SqlServerIp];Initial Catalog=[databaseName]User Id=newLogin;Password=newPassword; When I deploy application on my local IIS (which is not the same machine as database server)
it works fine, but when I deploy application on other IIS (the same machine as sqlServer) it throws an exception: System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. how to fix it? Maybe it is due to some bad configuration of IIS?

I recently upgraded a WinXP machine that had been running VWD 2005 to a Win7 machine using VS 2010. The application targets .Net 2.0, but since the upgrade, I cannot get VS to connect to my database and this is the first time I've tried working on the site since upgrading, so no changes have been made to any code (with the exception of trying to change my connection string so I can connect). The specific error is:Cannot open database requested in login 'dbName'. Login fails. Login failed for user 'SqlLogin'The sql database is on another machine and I was assigned the login/password; I know the login works because I can connect to it with SQL Server Management Studio. Having read several posts and still having trouble, I tried to do a couple things. First I modified my web.config connection string, which looks like this:
[Code]....
When that did not work, I deleted the connection string from the web config and dragged a sqldatasource control onto a page and tried to use the connection string builder while in design mode. Then the error I got was:The database db1 does not exist or you do not have permission to see it. Would you like to attempt to create it?I'm not sure I understand that there is a problem at all, except that I upgraded the OS/IDE. I'm using IIS 7.5 on my local machine to serve the development site while connecting to the development sql server on the other machine. Since I can't use the IIS aspnet account on the remote sql server and my assigned login is verfied working through sql management studio, what else can I do to get my developement site working again?
I just installed SQL Server 2008 Management studio Express on my Vista machine.i tried connecting to local machine using :
.sqlexpress, (local)sqlexpress, or .SQLExpress, MyPCNAMESQLExpress
nothing is working, getting this error:
----------------------------- Cannot connect to PC-NAMESQLEXPRESS. A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) ----------------------------
I have installed sql 2008 R2 and also sql management studio. I am able to connect to the db through windows and sql authentication. I have then installed VS2010 express edition. When I goto Database explorer, right click on data connection, I can see only add connection which is not grayed out. From here no matter what I do, I cannot connect to the db. Infact I get 3 optins 1. Acess database file, 2. sql server compact 3.5 , 3. sql server database file
I am using Sql Server 2008 to connect to a Remote Server. Everything was working fine for the last couple of months, and i was successfully connecting to the remote server. Today it suddenly stopped connecting to the remote server. note that i did not alter any configuration settings. Did my isp block Sql Server. My ISP is using ISA SERVER? The error details are:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (.Net SqlClient Data Provider) I am using Microsoft Firewall Client For ISA Server for opening ports. But today nothing is working.
OLE DB provider "SQLNCLI" for linked server "xx.xxx.xxx.xxx" returned message "The partner transaction manager has disabled its support for remote/network transactions.".

be it's a wrong place to ask the following question. Sorry for that. Our hosting provider has recently upgraded their database server from Sql Server 2005 to 2008 and I'm getting errors to connect with remote server from my development machine. Error Message "Invalid connection". Tried to find solution on net but couldn't find it.I'm using .Net 1.1. Though we've updated versions 2.0,3.5 & 4.0 but due to some certain circumstances I've no way to update it. It's a web based project. The following connection string works fine for Sql Server 2000 & 2005 but not for 2008.<add key="ConnectionString" value="Data Source=Remote Server's domain name;Initial Catalog=database name;User ID=user name;Password=surround;Persist Security Info=True;Pooling=false;Connect Timeout=45;" />Here Remote Server's domain name indicates to remote db server like: test.mysite4now.comdatabase name for example: test_surrounduser name like test_surroundpassword: surround.Can anyone inform me what's wrong with the above connection string to connect to Sql Server 2008.
I'm trying to publish an ASP.NET website over an IIS 6.0 (Windows 2003 Server), and I have some troubles trying to connect to the database. Curiously, I have installed another ASP.NET website into the same IIS 6.0 with the same properties and security parameters and can connect without problems with the same database. The application that works fine is almost the same that the one that can't connect with SQL Server (actually is the same but with several modifications).I'll enumarate some information related to the problem:
S.O: Windows 2003 Server SQL Server Engine: SQL Server 2008 SQL Server accept remote connections? Yes. ASP.NET version: 2.0.50727 The connections via TCP/IP are enabled to the SQL Server instance? Yes. The corresponding user that I have in the connection string, actually exists into the database with the "owner" role? Yes. ORM Tool used: nHibernate
I get the following error when I try to run the aplication into the browser:
Error while establishing a connection to the server. When connecting to SQL Server 2005, this failure may occur because the default settings SQL Server does not allow remote connections. (provider: Shared Memory Provider, error: 40 - Could not open a connection to SQL Server)
I made some test. For example, using the web app that works fine I can connect without any problema with the database that uses the web app that can't. With this evidence I concluded that the problem is within the web app and not into the SQL Server instance.
I am using Integrated Windows authentication and Role based authorization.The web.config file has two Active Directory groups.Sample code of web.config file for Role based authorization (Actually I got this sample code from a moderator of this site Gary works well).
So user's who doesn't belog to "Group1" AD group, should get Unauthorized error. It works exactly like that. But, before getting unauthorized error, it shows a pop up screen (as shown in the attached picture) prompting to put userid and password. If a user in AD group "Group1" accesses "Blood group. aspx" page, popup message doesn't come which is correct. Following is the code in web.config file to handle errors:
Code: The <customErrors> section enables configuration of what to do if/when an unhandled error occurs during the execution of a request. Specifically, it enables developers to configure html error pages to be displayed in place of a error stack trace. -->
Question 1: why does the popup box prompting user id and password comes up? Question 2: I have put in web.config file in customErrors tag to direct to Errors.apsx page when I get 401.2, it should be redirected to Errors.aspx page. But it is not getting re-directed.
in my ASP.NET applicaton I have ftpdata folder, where is MS Access 2010 somename.accdb file. On my local computer (Win XP), there is no problem to connect with OleDb to this file and read write datas into and from tables. But on server (Windows Server 2008), I cannot connect to the same file like on localhost.
I have an asp.net 2.0 application that is suppose to pick the Identity of the currently logged in user on a client machine and use it to setup working environment for the user. On win xp and windows server 2003 this works fine. but on moving the application to Windows Server 2008 R2 .
I started a new Sql Server 2008 with mixed authentication Windows and SQL SERVER AUTh... I created a new login account and use it to directly connect in SQL server managment studio BUT... when i create in VS2008 the connectionstring... everytime i try to open the DB connection i take an exception to the login... some screenshots show all the process ;)
LOGIN: admintvmaismais PASSWORD: ex Working to connect in SQL SERVER MANAGEMENT... LOGIN STATUS ON SQL SERVER MANAGEMENTE
Now in VS2008 Web-Config I declare the connectionstring:
<connectionStrings> <add name="SqlConnectionString" connectionString="Server=JP;Database=tvmaismais;User ID=admintvmaismais;Password=ex;" providerName="System.Data.SqlClient" /> </connectionStrings> and When i try to open a connection like this: SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["SqlConnectionString"].ConnectionString); try { conn.Open(); ... } catch (Exception e) { retorno = e.Message.ToString(); } finally { if (conn.State == ConnectionState.Open) conn.Close(); conn.Dispose(); }
I get this exception: Cannot open database "tvmaismais" requested by the login. The login failed. Login failed for user 'admintvmaismais'. What am I missing? What do i need to do, to get this login to work?
I am using VS 2008 that worked fine using the standard ASP.net security with the Web Administration Tool and SQL Server 2005.
I had to install SQL Server 2008 which also meant I had to uninstall SQL Server 2005. Now when I try to use ASP.net security by pulling the Login box from the toolbox to my form and then go to configure this I get an error.
"Unable to connect to SQL Server database."
How do I change this to work with SQL Server 2008?
