Configuration :: Unauthorized Access Exception Copying Files From One Server To Another?
Dec 21, 2010
I have been struggling with an issue that sounds like it should be quite common but I can't seem to get the thing working no matter how much I research it!
I am using an AJAX file uploader to upload files (up to 100MB) to the webserver and when the user clicks a button to complete navigate to the next page, I then attempt to move the files off the webserver onto a file server on Page_Load. Both servers are WinServer 2003. There just isn't enough space on the webserver to hold all the uploads once we go live with this solution so I have to get the files off the webserver.
Uploading the file and creating a new subdirectory on the webserver (to hold the file) works no problem at all. When I do the file copy to our file server locally on VS2008, again, no problem. However, when I delopy to the live server and try the same thing, the upload happens ok, but the file copy does not. I get an UnauthorizedAccessException. I don't have access to the webserver myself (but can request it if absolutely necessary) and our file server sits within the same domain (Active Directory).
I do not want to use Impersonation at a high level (web.config), so I tried it programmatically for the purposes of the copy file but it did not work. I used one of our general clerical accounts to pass in the credentials and gave full permission to this account on the file server to create/modify files.
I have created roles and users using ASP.NET configurations for login validations, it works fine if I run my application within project but when I publish my site and try to run from my Inetpub it giving this error. I tried all shorts of solutions posted in website but nothing worked for me.

Lately it's been taking about 15-30 seconds for my site to respond after copying new files into the bin folder. I do updates throughout the day to fix bugs, add new features, etc. It used to only take a couple seconds.
I have 4 files that get copied into the bin directory regularly. 2 DLLs and 2 PDB.s I use debug mode (I prefer it for the errors since right now I'm updating frequently), but have also tried release mode and it didn't make a difference. 3 files are 1MB and the other is 400KB. I've also cleaned and re-built but still the same.
It was only taking a couple seconds for the app to restart until a day or two ago. I'm not sure what changed. This is an active site so having a long delay is a problem. I've been tempted to try an iisreset, but that'll really create a problem for users on the site.
This is with IIS6, Win 2003, and .NET 3.5.
I looked in the .NET temp folder and it's not filled with garbage.
For a church website I'm managing, there is a need to place audio files (sermons) on the website. There will be two categories of audio files; one will be a sample size of the audio file, around 5 minutes in length. The other will be the full-length of the sermon (30-50 +/- minutes).
I have decided the best setup would be to place the audio files on the server. I would then store the audio information, as well as the path to the audio file, in a database. I had thought about placing the audio files in the database as a BLOB, but it seemed inefficient. My concern, is with tools like Mozillza plug-in "Download Helper" , it is so easy to simply grab the media files off the server. This would not be a big deal, except we want to sell the full-length audio files. I am running ASP.NET 3.5 on IIS 7.
I know you can copy a Website intact to the server and have it run normally (security and compilation time aside). What about the projects that are in the solution? [whose dll's are copied to the bin when built]. Is there a way to copy the projects' code files to the server as well?
My goal is to be able to debug [by modifying code in the project if needed] directly on the server without having to install an IDE [or keep building on dev machine and copying over dlls]. I can debug/modify the website files, but not the projects.
I am new to MVC. I am using MVC and VS2010. I am trying to publish my website to a remote server. All files are copied except some static pages i have kept inside a folder. for e.g. i have a folder named Content. I have around 5 .pdf files inside this folder and also a .css. When i do Build->Publish <appname> all the files including the .css is copied but not the .pdfs.
My code can be found here http://stackoverflow.com/questions/3604864/c-asp-net-ftp-error I am trying to download a file from an FTP server when I try to download it it says I do not have access I have been googling this all morning and have not had any luck. I went to the designated folder and added Everyone with full permissions hoping I was missing a user and that did not work. I tried giving full permissions to myself, Anonymous user, network service, and a few other users that I have found. I have tried using
<identity impersonate="true" /> and <identity impersonate="true" userName="myfullusername" password="mypassword"/>
I am still not having any luck the full error I get is:
System.UnauthorizedAccessException: Access to the path 'C:UsersmynameDocuments' is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy, Boolean useLongPath)
I have wav/mp3 files that I want to grant access to only users after signing into my webapp. I have the user credentials being checked through a mySQL db. I do not want the files to be able to be accessed by url. I have found that adding the mime type to the web.config section at
will disallow access to the files by url, but how can I allow access programmically to the files after signing in?? Currently using godaddy hosting.
Apparently, DNN installations do not like to be precompiled (they won't be able to find any localized strings then). Our installation is safely put in SVN, which means I cannot just copy the whole directory. To publish everything, I need to copy the whole website directory without the SVN files and directories. So far, I've been messing with good old DOS commands, which is time consuming and error prone.
an MS-Built script or step to do just this? Or can I do this using default Visual Studio 2010 commands?
I have subdomain "s1" which points to "a" folder. I want to know how could I access to files stored in "b" folder form subdomain "s1". My issue is that files I have some html content which saved in DB Records and their path are base on webroot i.e. "<img src="/b/movie1.avi" /> .Could any one tell me how I could show these files via subdomain "s1"
I am working with Staff Images and Staff Dependants Images (photos) and I have to deal with such images among Adobe LiveCycle Forms, File System JPEG Format, Storing them in SQL Server, and finally, displaying them in regual web forms (ASPX).
In order to have the most reasonable and flexible desing, I did the following to:
1. Load the image from predefined location defined in web.config.
2. Convert the images to Memory Stream,
3. Convert the images to Base64 format,
4. Convert the image to XML Node.
In web.config, I defined the following:
I load the Staff Photo into Memory Stream as follows:
And I create the Base64 XML Node as follows:
As a matter of fact, all above is working 100% correctly while dealing with Adobe LiveCycle Form, for Loading and Saving Imgaes from/to PDF.
The above method will allow me to finally save images to SQL Server field type varbinary(max) and also into File System as regular image files. Also, I have full security and control over the images, becuase the above method will allow me to have full control for who is authorized to get/view the images. The end-user does not have direct access to where the images are stored.
How to use the above method to display the image on a regular ASPX Web Page using Image Server Control ? I do not want to use the src='path to image file', I want to be able to push the image content/binary to the IE without providing a link to the image file, how I can do this ?
My objective is to prevent the user from having direct access to the image files from the Browser.
I wanted to transfer the website I was creating on my PC to the laptop so I can show it to other people, but when I try to start the copied website I get the following error: "Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class (e.g. Page or UserControl)." File is: MasterPage.master.cs and the Line is: 1.
As the website on my laptop is the exact copy of the website on my PC I don't understand what the problem is and why did it happen.
Am I doing something wrong? Is there any other way of transferring website from one PC to another. I have to add that the website is running on localhost.
I'm setting up a new site on a new server. I created the site in the IIS manager and pointed it to my site directory. But, I now receive this error each time I try to navigate to the site.
I didn't receive this error on the other server, so I'm a little confused. I looked this up, but most of the information I've found is about configuring the users that people have setup. But, this site won't be secured like that. No one will need to log in.
We recently migrated our ASP.NET 2.0 application to ASP.NET 4.0. It is running on Windows 2003 with IIS 6.0. After migrating, we have found that the ASP.NET 4.0 worker process w3wp.exe crashes intermittently with an 'Access Denied' exception. The stack trace of the exception does not point to any code written in our application. We are clueless as to what could be causing this. The worker process crashes when it makes a remoting call over http.

For more information, see Help and Support Center at [URL] We have tried options like giving permissions to ASPNET account in the WMI services under 'Component Services' but to no avail. Has anybody else faced this issue?
This is really a couple of questions about preventing unauthorized attempts to access a specific file type. Here go the questions:How do I prevent users from directly requesting a type of file? Do I write an HTTP handler?After preventing a direct download, can my app still explicitly serve that file type? How?
Brief Description: I want to be able to use my asp.net application to access files on another server used as a file system(storing .pdf, .xls, .doc files etc.). In Depth Description: Right now the web page has a gridview. The gridview has links to documents using paths like \servernamefilename. Our server guys said that this method would be using a CIFS protocol and would not work.
That we would need to set it up so that the application accesses the file through a service account or something. Does this make sense to anyone and can any provide a more in depth explanation. What would we have to change programatically to have our .net application access files on another server?
