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.
I had this one working a while back i try to upload file to my root folder it works locally but when i try it from my website i get the following error: exception details: system.bet .webexception. unable to connect to the remote server

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).

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 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 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.
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?
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" />

Below is sample code. This is working fime with out threads..if i am using thread only one request is getting executed and all others are giving error.
why I'm getting this error? I just re-created (not migrated) my app that was in ASP.NET 1.1 to ASP.NET 2.0. Whole app works perfectly. The only problem I'm getting with this piece of code for the Web Services. I'm running both versions at the same time side-by-side and it works fine in 1.1 and doesn't work in 2.0.

Bam! Error! The remote server returned an error: (500) Internal Server Error.
In IIS we have a virtual directory (named as "Documents") with in application virtual directory (named as "Reference") that points to an shared folder.All the files with in the "Documents" folder are listed and opened by the user (by clicking on the file name) with in the application
"Reference" application runs under an application pool. This application pool is configured to run with an Active directory account. This AD account has been granted write and modify permissions on the shared folder that contains the html files.
When user tries to open any of the html file located with in the shared location from the application following error is thrown.
System.Net.WebException: The remote server returned an error: (500) Internal Server Error
I tried to browse to the location manually and I can see the required files there.
These files where accessible from our application until yesterday. But we started encountering this error from today.
Is there any IIS settings that needs to be modified?
