App Data - Getting Access Denied Trying To Read A File In App_Data In A Project?
Jan 24, 2010
I've an XML file stored in App_Data which is only used to read some configuration on startup. When I attempt to open it within my code, I get an Access to the path ... is denied message.
I'm having trouble understanding why, and how to solve it. I guess in theory I should alter the permissions on the file (and directory), but this hasn't changed anything.
To give a bit more background:1. Its a file bundled with the project, so the setup created by VS2008 writes it to the correct place during install. I didn't think I'd need to do anything unusual post install such that the ASP.NET application would have access.
2. When I've tried publishing this locally, I've not had any problems. - This is only on a test Windows 2003 server.
3. I've ran a simple page to understand the effective user of IIS - It is NT AUTHORITYNETWORK SERVICE. I tried granting "Full Access" to this user to this file, and still it doesn't work.The code to open it is simple:
FileStream fs = new FileStream(Server.mapPath(s), FileMode.Open);
Where s is defined as '~/App_Data/myfile.xml
I've even copied and pasted the full path & filename (from the exception) and tried "dir" on it, and it is indeed present (to get around a typo for example).I've also tried running aspnet_regiis.exe /s

So, i am running SQL Server 2008 R2 Express and VWD 2010 Express on Windows 7. I am logged in as admin on my machine. I have created a new web app project (VB Linq to SQL) and I have attempted to add an existing .mdf to my project's App_Data folder. I right-click, choose "add existing...", navigate to the .mdf file in the C:Program FilesMicrosoft SQL ServerMSSQL10.SQLEXPRESSMSSQLDATA folder, and then i get an "Access is denied" error box with no further details.

I'm trying to make an executable in VS2008 that will read a webpage source code using a vb.NET function into a string variable. The problem is that the page is not *.html but rather *.aspx.
I need a way to execute the aspx and get the displayed html into a string. The page I want to read is any page of this type: [URl]
I have tried the following code, which works properly for html pages, but generates the wrong source code with "access denied" for the page title when I pass in the above aspx page.
Dim myReq As WebRequest = WebRequest.Create(url)
Dim myWebResponse As WebResponse = myReq.GetResponse()
Dim dataStream As Stream = myWebResponse.GetResponseStream()
Dim reader As New StreamReader(dataStream, System.Text.Encoding.UTF8)
Dim responseFromServer As String = reader.ReadToEnd()

I have an existing application that was written in .NET 3.5. The piece of code in question is using the FileUpload control and its SaveAs method. Its worked perfectly for the past six months, but I've recently upgraded the project to .NET 4.0 and I'm now receiving an "Access to path (...) is denied" every time the method is called. It works fine locally in dev mode but fails on my prod server. I've upgraded the website to run under .NET 4.0 and I've made sure the account (Network Service) it runs under in the app pool has full control. Other than upgrading to .NET 4.0, nothing has changed for the project.

I have an application that allows users to use a FileUpload object to upload files to a directory on the web server. The upload part works fine, but if they later try to delete the file they get an error that Access to the path is denied. The Application Pool for the site runs under NetworkService, and on the folder they are loading and trying to delete these files from I give NetworkService Full control. What else I may need to do?

My code is not being allowed to save an xml file in a folder on my server. Why is this?
you can see the error page here.. http://www.deutsch-english.org/
It seems to say something about not being authenticated and adding users to the config file. However this code has nothing to do with any users or groups, I just want it to always have permission to save files on the server. The code is purely internal, more like the core innerworkings of the site, it has nothing to do with users. I don't want to have to authenticate it, it shouldn't need authenticating, I just want it to work.

I am getting "Access Denied" error when I am trying to write a file on my hard drive (C:/.... xmls/test.xml) from a webservice which is also on my local machine.
The folder structure is like this
AdminApp (Web Folder on C drive)
- WebServices Folder
- TestService.asmx
-Xmls Folder
- Test.xml
I tried following settings in IIS in my efforts to resolve the issue:
- Set anonynmous access checked with my account name and password under "Account Used for anonymous access" alongwith integrated windows authentication checked. I am a admin on my machine.
- Disabled anonymous access with only integrated windows authentication checked. I have identity impersonate = true set in my web.config.

While uploading file on live server i get this error.
System.UnauthorizedAccessException: Access to the path 'xxxwork-max.comTelecomimageslogo.gif' is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
<identity impersonate="true"/> promotes for user name and password each time i select
file uploading.

I'm moving applications from IIS6 to IIS7.5 (win 7 an win server 2008 r2), when 2 applications (with identity impersonate) try to get a file with response.writefile only from a UNC path i'll get "access denied". In IIS6 and Visual Studio Developer Web Server, same code works. I can save file with FilePath.SaveAs and get name and length with FileInfo, but not download. After 2 days of nightmares I have tried to change
Response.WriteFile(filePath)
to
Response.BinaryWrite(File.ReadAllBytes(filePath))
and now work. My question is: can I have a microsoft developer to sacrificate for my avenge?)

Uploading file using upload control resulted in access denied
does not have write access to 'C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files'.
I gave the access to that particular user using web config :
<identity impersonate="true" userName="username" password="password"/>
but then that resulted in the above error. My intension is to upload the file for a perticulr folder.
I know the path.
I am not able to grant the persmission for the folder from control panel. Is there any work around.
