Web App Unable To Access Remote File Through IIS 5.0
Jul 27, 2011
I have this web app that works just fine when I run it on IIS 6.0, but when I run it on a different machine with IIS 5.0, it ends up having file access problems. Basically, my web app uses a COM object, and this COM object uses resources, such as files, and these files are located in remote machines. A sample code would be:
Code:
MyComObj com = new MyComObj();
com.UseDataFiles("machineBdata.dat");
Again, it works fine on my machine with IIS 6.0, but in my other machine with IIS 5.0, it gives me an error. To be more precise, it's the COM object that gives me an error; the com object tells me that it can't find the file. What's weird is that when the web app calls this line:
System.IO.File.Exist("machineBdata.dat");
It returns True, which means my web app has permission to read, but when it does it through my com object, it can't see it. Again, I dont' think it's the COM object that has the problem since it runs fine on IIS 6.0. In fact, I ran a windows form application (that uses the COM) on the machine with IIS 5.0, and it works fine.
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
the code bomb at the following line
requestStream = uploadRequest.GetRequestStream() 'This is where the exception occurs fileStream = File.Open(localFile, FileMode.Open) [code]....
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.
the below code is use for my website to insert photos, On my compouter, i can insert pics but when i transfer it to the remote machine, i get error message. Here is the code:
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 am not able to debug a Remote web project (Where the project files are located in another server which is in the same network). I am getting the below error message:

It works fine when i try to access the website through IIS. Shud i do some setting changes on VS 2005?
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 made a project to use the access membership provider from [URL] and it works. But I need to edit my database but when I configure my database, I cannot see the tabel, I can only see the queries in mdb file. when I select the field from query, I am unable to update it. My code is as follows:
I have a form wilh couple of Drop downs and text boxes and a Data Grid View which displays data from Access Table. When I hit add button on the form, I can see the data being added to the Grid View. But when I close the form and open the Access Database File (.mdb), the respective table is empty. The Access Table is not being updated. Second time if I open the form, the Grid View is also empty.I am pasting my code here.

I'm trying to force a large (200+ MB) file to download that's on a remote server. The problem is that I can't use the "WriteFile()" function, since I'm not using a virtual path. Then, when I try:
I have an ASP.NET MVC site that is running into some conditions that it is pegging the processor on the iss boxes it's running on. I don't have access to these servers (it's a farm of about 5 iis6 boxes behind a netscalar). I am doing some logging to a sql database, but the problem is that when the cpu pegs my database starts timing out. The iis servers are hosted in house, but I can't get access to them.
And to make things ever more complicated, I can't reproduce any of these issues in my qa environment (which I don't have access to either). QA is setup to similarly to our prod environment, but it runs on a single box that isn't behind a netscalar.
We have staging server and production server for website. We will move the changes from the staging server to the Production server through the FTP.
Since we have the product release for every 3 months. So, we need to redirect to the latest version in the Production server IIS. Is it possible to access the Production server IIS and redirect the web site link from staging server ?

i have created a bat file to run the aspnet_regiis exe to encrypt the connectionStrings of web.config file on the remote machine. the same is working when i ran the file on remote machine itself. but is it not working when i call it from another bat file from my local machine which is shared with remote machine. my code loos like:
I am uploading video files, which are somewhat large (5mb - 50mb) via asyncfileupload. I am able to successfully uploaded files of all sizes up to 1.5gb, that I've tested, on my test server and also locally on the production server. It works great, locally.
However, when I process the form that is hosted on my VPS server from my home, it tanks out and I usually receive the error: Access is denied. However, it works occasionally for small files. <1.5mb
I have edited and re-edited all of the associated config files, etc...So it shouldn't be a file size issue-especially since large files are successful locally.
I've also adjusted the UploadReadAheadSize attribute as described in another forum.
I set all of the folder permission so that everyone can read write as well as IUser, IIS_WPG, IIS_Iusr, Network Service am I missing a permission field?
Does anyone know of other settings that I would have to implement in order to get this working for my users.
are there any c# tricks for slower connections?
