DataSource Controls :: How To Connect Server Explorer To A Remote SQL Server Database
Mar 13, 2010
I have created web pages using VS Web Developer that use a local Developer Edition of SQL server database on my PC with LINQ to SQL. When I deploy my website to a remote web host SQL server, I need for my web pages to be able to use the remote database instead of the local database. So, how do I get the Server Explorer to connect with a remote SQL Server database?
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 tried this code by inputting the ftp address as ftp//: and the correct username and password and I get the following error
"Unable to connect to the remote server" on line :
FtpWebResponse Response = (FtpWebResponse)Request.GetResponse();I tired this on my ftp server provided by a hosting service and an anonymous ftp located at 193.166.120.5 ?
Note: I was able to connect to both of these ftp through filezilla, via a webbrowser, and through windows command line.
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.
By right clicking on my database i created a query in server explorer. But where are this query stored can't find them back. I should aspect that their is a folder query's like there is a folder tables but this isn't the case.
I have a problem, my database reside on a separate server and my online website need to access that server to get some data. The server is in my office and connected with Internet.
I have configure the SQL server 2005 on the server to allow remote connections. Enabled TCP/IP and named pipeline. The port is 1433.
2. <add name="DatabaseConnectionString" connectionString="Data Source=nt1111;Initial Catalog=testdatabase; User ID=test;Password= "***"; User Instance=False" providerName="System.Data.SqlClient" />
3. The same as 2 but with IP <add name="DatabaseConnectionString" connectionString="Data Source=999.99.9.99;Initial Catalog=testdatabase; User ID=test;Password= "***"; User Instance=False" providerName="System.Data.SqlClient" />
This issues has been driving me nuts. I am trying to follow the tutorial on [URL] I am trying to connect to a database in Microsoft SQL Server 2008. The way I do this is by right clicking on the "Data Connections" > Add Connection. Afterwards the Add Connection window comes up, I make sure my data source is "Microsoft SQL Server (SqlClient). And, I choose a server name; the only server I can choose is DomainSQLEXPRESS. The issue is when I go down to the "Select or enter a database name" drop down box, I do not see my database listed. I have also made sure in the SQL Server Management Studio that I have given my user all the privileges for the database. I know my explanation is kind of vague, but would anyone know the reason why I would not see my database?
I need to insert a record in table which is in remote server....I am using two connection strings for local and remote....both the servers are in same workgroup only...so am able to connect the both.The problem is am filling data of local table in on dataset1 and remote server table data in another dataset dataset2..Now whil inserting a record local an error occured like "This row already belongs to another table" after googlingI found like this like "Dataset.importrow()" instead of "dataset.add()" method...then there is no errors but the inserted record is not inserting in remote server database...
I have installed oracle odp.net (11.1.0.7.20). This client installation includes all VS developer tools.
All my application seems to be working ok. I have never attempted to use VS Server Explorer.
For ReportViewer I was trying to create a dataset and in the server explorer I was trying to create a new dataconnection for oracle. As soon as I click new connection I get the following error.
An unexpected error occured in Oracle Data Net provider for .NET. contact the provider vendor to resolve this problem.
Also I am unable to add a server to the server explorer. When I enter the IP address of
oracle DB Server, it gives the following error.
An error occured while connecting to 999.99.99.999
I just ran a project that I've been working on and the project couldn't connect to the sql server engine. This project worked fine yesterday. This morning I installed the new Adobe Flash player 10.0. That's the only thing that's changed sine I last worked with my project.
I got an exception for the sql server error when I run my app. This is the exception from the app:
Exception Details: System.Data.SqlClient.SqlException: 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 tried to connect to the engine with the ssms but couldn't connect that way either. This gave me an error that said:TITLE: Connect to Server
I am unable to connect to my local instance of SQL Server 2008 Express using SQL Server Management Studio.I believe the problem is related to a change I made to the connection protocols. Before the error occurred, I had Shared Memory enabled and Named Pipes and TCP/IP disabled. I then enabled both Named Pipes and TCP/IP, and this is when I started experiencing the problem.
I have now set Named Pipes and TCP/IP back to disabled. When I try to connect to the server with SSMS (with either my SQL server sysadmin login or with windows authentication), I get the following error message:
"A connection was successfully established with the server, but then an error occurred during the login process. (provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233)"
My first question here is: why is it returning a Named Pipes error? Why isn't it using Shared Memory? It seems like it is not listening on Shared Memory for some reason?When I set Named Pipes to enabled and try to connect, I get the same error message.My windows account is does not have administrator priviliges on my computer.
I have 2 servers. the database server (DB1) which has sqlserver installed and the application server (WEB1) which has my web application. They are both on the same network and both have the same administrator login.
My web application on the application server needs to access the database on the database server. sqlserver is set to mixed mode in security. i created a random sqlserver user login that can only access my database and set it as the db owner. I use the username and password for this in my connection string. when i run my web application i can read information but i cant write to the database. My app is using windows thentication. I have set my NT AUTHORITYNETWORK SERVICE account to db_owner for my database as well... grabbing at straws!
Question 1: When my application talks to sqlserver does it use the administrator login or the NT AUTHORITYNETWORK SERVICE account which i got from using windowsidentity.getcurrent()?
Question 2: If I use ASP.Net impersonation, what does this do exactly? Because if i run the ndowsIdentity.GetCurrent() i get the username that i specified. How does this tie in with my connection string?
Question 3: If I dont use impersonation what and how do i have to configure sqlserver to accept my insert/update requests? Do i need to work with the NT AUTHORITYNETWORK SERVICE? or can i just use my user login? What do i need to add or remove from my connection string? (see below).
how to edit my web.config connection string mentioned above using the details provided above so that it connect to my MSSQl2005 hosting provider .... ?
I don't know how to edit connection string to do that !!

I am working on a project where one of the requirements is to re-write an ASP.NET application. The old ASP.NET application was based on .NET Framework 1.1. The new ASP.NET application is based on .NET Framework 3.5.
One of the functions in the old web application was the ability to send email. The old code used the System.Web.Mail.SmtpMail class, whereas the new web application uses the System.Net.Mail.SmtpClient class.
In testing this on our development servers, everything worked fine. However, we have two beta clients testing out our software, and they both run into problems sending email in the new web application.
The specific exception is as follows:
"Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it"
Both the old and new ASP.NET application are on the same server (Windows Server 2003). They both are using the same Exchange mail server. Why is it that the old ASP.NET application can successfully send email, but the new one cannot?
I looked at the old code, and it did not use any form of authentication, it just specified the sender's email address, the recipient's email address, the subject, body, and server, and sent the message. I did the same thing in the new code, with the only difference being that I used the SmtpClient class.
Below is a code snippet from the new ASP.NET application:
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage(); mail.To.Add(messageTo); mail.From = new MailAddress(messageFrom); mail.Subject = messageSubject; mail.Body = messageBody; SmtpClient client = new SmtpClient(); client.Host = smtpServer; client.Send(mail);
when I call the web service from the windows service. But I can visit this web service through IE and I also wrote another console application to call the web service and it works fine, too.
The exception infomation is below:
A socket operation was attempted to an unreachable network 127.0.0.1:8888
I try many methods, like turn off the firewall and anti-virus software, set the web services proxy property to null. but still cannot solve this issue.
I have a local database which is updated regularly. Now I need a good way to reflect the local database changes into the remote sql server. Both the server have same database structure.
All the above pocess should work automatically from the local database server because I need to update the remote one so that the website visitor can get the updated results in the morning.I need a detailed description/ procedure to accomplish the work.
My site sends confirmation emails from a purchase. 95% of the time, it works. The other 5% after clicking the 'Confirm' button that runs the payment and should send the email, i get the following exception:
Details: Exception: Failure sending mail.
Inner Exception: Unable to connect to the remote server
Inner Exception(2): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 72.167.234.197:25
The code to send the email is this:
Dim smtpClientPayPalSuccess As System.Net.Mail.SmtpClient = New System.Net.Mail.SmtpClient() smtpClientPayPalSuccess.Host = "relay-hosting.secureserver.net" smtpClientPayPalSuccess.Send(mailMessagePayPalSuccess)
FYI: I have confirmed with the hosting that I don't need any credentials, or a different port number than 25. This is also running over https. why this would be happening only a small percentage of the time?
