VS 2008 How To Connect To A Database On A Remote Server
Apr 15, 2010We have a database on our server, here at the office. We now want to create a asp.net website that will be accessible to the public.
Say the domain of the website is [URL] and it's hosted on a webserver of HeartInternet.
When someone connects to that domain, that webpage must be able to pull data from our server that is located here in our office.
In other words the webpage cannot just load data out of the MySQL database loaded on its server, but it has to connect to our server and get data.
DataSource Controls :: How To Connect Server Explorer To A Remote SQL Server Database
Mar 13, 2010I 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?

How Does Web App Connect To Remote Sql Server
Jan 25, 2011I 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).

SQL Server :: 2008 Connect To A Remote Server - Network - Related Or Instance - Specific Error
Aug 4, 2010I 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:

C# - SmtpClient - Unable To Connect To The Remote Server
Jul 13, 2010I 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);

C# - Unable To Connect To The Remote Server From Windows Service
Nov 9, 2010I have got this error
Unable to connect to the remote server
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
Here is my code:
WebImageSVC webSvc = new WebImageSVC();
ConfigManager.LoadConfigManager();
webSvc.Url = ConfigManager.WebSvcAddress;
webSvc.Proxy = null;
webSvc.CanUpload(0, "");
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.
Asp - SmtpClient.Send Exception - Unable To Connect To Remote Server
Mar 6, 2011My 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?

Can't Send Smtp Email From Network Using C# Error / Unable To Connect To The Remote Server
Apr 1, 2010I have my code here, it works fine from my home, where my user is administrator, and I am connected to internet via a cable network.
But, problem is when I try this code from my work place, it does not work. Shows error:
"unable to connect to the remote server"
From a different machine in the same network:

I checked with our network admin, and he assured me that all the mail ports are open [25,110, and other ports for gmail].
Then, I logged in with administrative privilege, there was a little improvement, it did not show any error, but the actual email was never received.
note that, the code was tested from development environment, visual studio 2005 and 2008.

SQL Server :: Use Management Studio With Database Created Within MS Web - Connect To New Database?
Mar 30, 2011I have created a web application and an SQL database using Web Developer 2010 Express. I have SQL Server 2008 and SQL Server Management Studio Express. In order to deploy the database to my hosting space I need to create a .BAK file from my new database. I think I can do this from with the Management Studio, but can't figure out how to get it to connect to the database.

How do I connect to my new database?

SQL Server :: Project Executable Can't Connect With Database Unless Installing SQL Server
Nov 7, 2010I am developing and app to find automatically characters stats with the 2nd edition dnd rules to be easy for my party to create characters when we play.
I am using Visual studio 2010 c sharp express and Sql 2008 express R2.I have added a database in the project to have all the data needed. When I use the release folder or the debug folder on other pcs the app doesn't run. Wherever I install SQL server (database and management) things are fine. I googled but I am not sure what to look exactly for and made a brief search here but with no results. I am trying to make sth that has almost no dependencies but well I can't avoid installing .net framework 4 everywhere...
Is there anyway to make database work without installing SQL? Is there any workaround like a dll or sth?
