View 5 RepliesI wrote an asp.net application that I'm trying to run on a godaddy domain I bought. I need to read a file in a folder that I did not give read access to so that your average user cannot see in the informaion in that folder. I assumed that the asp.net program would have the same credentials as myself because server-side code. Turns out I am wrong. When I go to use the asp.net application it throws an access denied error saying that the ASP.NET user account has to be given permissions to access the folder.
After talking to two different tech support people at godaddy I've come to the realization that they are either dumb or lazy (or a combo of the two).I came across some code that you can put into the web.config file that would allow the asp.net application to impersonate a user, which would work great to use myself as the impersonated user. However it seems that godaddy cannot give me the name of the server that my domain is on (that's understandable) so I don't know what to put in the identity tag to get this to work.
Here is the code I found:
[Code]....
(of course I filled in the username and password with the correct info)
When I went to use it again it threw this error:
System.Web.HttpException: The current identity (PHX3username) does not have write access to 'C:WindowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files'.
I want to remove execution permission for one folder in the site.
For example:-
I uploaded files to one folder called "Downloads" .
so, user can download those file just browsing "http://localhost/downloads/uploadfile.wmv". But problem is once user uploaded ASPX page (default.aspx). then user can browse like this http://localhost/downloads/default.aspx". In that, if he wrote so code for removing files..!. So, I don't want to run the script in this folder, I just want to show that file as text output.
Note:- This I can handle by using my own code to display files(ASPX, ashx and ....). But, I want to allow the user to access directly to that file.
Is it possible to use a small .NET page to set folder permissions on some folders on the server where it resides? What is the code or objects that can be used for this? I am on Windows Server 2003.
Basically I want to hit the page with a GET or POST and have it run and check and/or update the permissions on a folder.
I am using windows authentication without impersonation on my company's intranet website with IIS7.
Under IIS7, what account is used to access the folder which contains my web app using these settings?
Would it be IIS_IUSRS? Or NETWORK SERVICE? Or another I don't know about?
I am trying to access a shared folder which is located on a different server rather than on the asp.net server.
I configured windows authentication and set impersonation to true. Also try with enable/disable basic authentication.
I have tried the following:
with a mapped driveshared folder access (\sharedfolder)virtual directory pointing to shared folder with pass through configuration. However none of the above works. I am getting "Access Denied" error when trying with shared folder and virtual directory. In the case of mapped drive getting "Not Found" error.

Trying to restrict access to folder but can't?
I'm using Visual Studio 2008 on my local PC. My Code kept on network Drive. when i am trying to run it from my local machine i am getting below security exception.is there anyway i can Grant Permissions to network folder?

Just got a new dev machine and am having trouble with this piece of code in our project. I have set folder permissions to give Network Service read/write accessFor dev, this is being ran locally on IIS 7.5. IIS Authentication settings are Forms Authentication and Windows Authentication enabled.I am getting a permssions error when the xml is written to the local hard drive.
PDFGenerator pdfGenerator = new PDFGenerator();
DataSet dataSet1 = pdfGenerator.GenerateDataSet(Parameters, xmlFilePath);

I have a folder that cannot be accessed by anyone except the management role of my web site. But, I added a folder to this and it can be accessed by anyone.
Of course, I can explcitly set the access to only a specific role(s) but I would like to know if I can tell set it so that even folders nested inside a restricted folder can take on the same permissions settings as the folder in which it is nested.
At first I got an error that the user did not have permission to read the config file (web.config).
So I gave NETWORK SERVICE and IIS_IUSRS read on the website folders.
But now vistors can not access images and other static content from the Content folder without logging in. Aspx and .ashx content works however static content is redirected to the login page.
I wrote a web service sometime back, and uploaded to one of our network Server's IIS. The webservice needs to access a network folder, which was working perfectly fine till a month ago. Now, when we use the webservice in our .Net application, it fails with the exception message "Access to the path '\<networkMachine ><Folder >' was denied" (may be some group policies changed). But when I run the webservice from my local machine's Visual Studio debugger, it can access that folder. What could be different on the server's IIS w.r.t. my service? Why was it able to access the network folder before but not now? Please note that I can manually access that shared network folder from my machine, and also when I remote desktop to that <networkMachine> from windows explorer.
I saw in the task manager on the server that the IIS process w3wp.exe is running under 'NETWORK SERVICE' account. Though the network folder is not shared specifically with this account, but that has given read & execute access to 'Everyone'. Then what is the problem that it cannot access the folder. By accessing I mean creating a 'DirectoryInfo' object of the path '\<networkMachine ><Folder >' and reading all the subfolders -
just read.
I have a folder with username and password over it.I wanna make a page where i can access files under that folders in .net and be able to download them.How to code that in VB.net?
View 2 RepliesMy restricted files are all stored in ~/Secured folder on the root. Authorized users have no trouble accessing aspx files in that folder. Recently I added a part of an application whose files I wanted to keep separate and created a ~/Secured/HR folder. I am getting a "resource not found" error trying to use any aspx file in HR folder even after user successfully logs in, as if the file does not exist at all. Here is my web.config security settings:

Do I need to configure security for that folder separately?
the only way to make themes work is to allow user "Everyone" to access the folder App_Themes. I am wondering if a more specific user instead of "Everyone" can be granted the access to allow themems work.Account "IIS_IUSRS" and "NETWORK SERVICE" have already been granted access.This is about folder access of Windows 7 running IIS7, not web page authorization configured via web.config. The web page is browsed via local host (i.e. the web page address is something like "[URL]
View 1 RepliesI have a web app, which contains a folder Uploads, to which users (authenticated) upload their files (for some reason it has to be a folder in the root of the web app).I want to deny access to this folder and files to all non-authenticated users.
In my web.config I have:
[Code]....
and everything seems to work in development, but on a staging server it redirects non-authenticated users to login page ONLY from aspx pages, but not when entering the url to the file in Uploads folder.
I have a problem in my asp application. In my application I have an own authentication mechanism so in the web.config file I have <authentication mode="None"/>
Inside the application users can upload files to the folder I've created (App_Files). I would like to give access to the folder only once they are logged in (Session["Login"] is no null).
I dont want not logged in users to be able to access the files over a url address in the browser (like http://<server>/App_Files/Filename.pdf)
I set up a secured folder in my website. When I access this folder via web page, it pop up a windows login form to ask for user name and password. I would like to code the asp.net page or java script to access this secured folder with username and password without pop up the login form. find the method for asp.net page accessing the secured folder automatically.
View 2 RepliesIn one of my website I need to prevent direct access to non .aspx pages in a protected folder. Authentication works fine if I am going to [URL] but in one case my users are uploading html pages in that folder and if somebody cut and paste [URL]the page can be seen without the authentication process to be activated.

I am implementing membership provider. For example, anonymous users are not allowed to acces pages under the folder, namely XXX.
When user clicks to navigate any of those pages I would like to display a popup window. I know I can implement button clikc events. But there are many buttons and links. What is the most effective way to do that?
i have a problem with forms authentication. i have a website and want to restrict access to an especific folder. i want the access to this folder be made via the login form this is what i have in the web.config

Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.
I am doing some testing and want to find out best practice for creating a new user to assign to an appPool. I know that the default ASPNET account, on IIS 6.0, is very low permissions. For experienced folks, what are the bare permissions required to grant this new user? Yes, I am aware that various NTFS rights are required for different operations, such as reading outside of the application path, writing to the NTFS share, etc. I am just looking at a base install.
Dino Esposito wrote in Chapter 15 of Programming Microsoft ASP.NET 2.0 - Core Reference that the following directories would need the respective permissions:
.NET framework root - read/list Temporary ASP.NET folders - full GAC - read Windows System32 - access/read App root - access/read Web site root - scanWhat else would I need to set up beyond this base configuration as far as rights are concerned? If anyone does this regularly, do you have a script to do this automatically?
Here is my code

"fileUpload" is the FileUpload ASP.NET control. The SaveAs method writes the user uploaded file to a specified location on the server. IT WORKS. That tells me that the ASP.NET process has the proper write permission to write to the file.The next line uses an assembly called PdfSharp which you can use to open PDF files and manipulate them. In this case, the line simply opens up the user uploaded file. That is where the error occurs. WTH?
It works on my production machine. It does not work on my local machine. It USED TO. It was never a problem before.So why would it be fine to WRITE to the server, but trying to open a file give an error? Makes no sense. Googling yields a suggestion to put <trust level="Full" originUrl="" /> under <system.web> in web.config. It does not work.
