Access is denied. [modified]

Im a beginner

Hello all, I have an asp.net page uploading a file to D driver. It works well with ASP.NET server. protected void Button6_Click(object sender, EventArgs e) { FileUpload1.SaveAs("D:\\a.txt"); } when I published (to IIS) and ran it from IE, it caused an error: Access to the path 'D:\a.txt' is denied as following. [UnauthorizedAccessException: Access to the path 'D:\a.txt' is denied.] System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) +651 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) +1038 System.IO.FileStream..ctor(String path, FileMode mode) +64 System.Web.HttpPostedFile.SaveAs(String filename) +87 System.Web.UI.WebControls.FileUpload.SaveAs(String filename) +22 Examples.Button6_Click(Object sender, EventArgs e) +20 System.Web.UI.WebControls.Button.OnClick(EventArgs e) +105 System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) +107 System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +7 System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +11 System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +33 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1746 Best regards, P/S: The code for this problem is here: I have an ASP.NET and this is the code in default.aspx:

Does D: Drive exist on your server? Is it writeable, or is it a CD Drive? Do you have permissions to write to the root of D: Drive? Does your IIS process user have permissions to write to the root of D: Drive?

Yes, D: Local Drive exists on my computer. I do not know whether I have permissions to write or not, but when I run the page using ASP.NET Server, It works well. After I published and then used IIS Server, It threw the error. I do not know how to check permissions both the root of D: Drive and IIS process, and I need your help. Thanks,

Your computer is the server ?

A website should not have permission to read or write above the application root, so even if you have a D drive on your server, I'd expect this not to work.

Check Security permissions in d drive folders. Set every one to access permission Thanks, Raja

No, D: is my Local Drive and my computer is not a server. I have that project on my personal computer.

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Button ID="Button6" runat="server" onclick="Button6_Click" Text="Button" />
<br />
<br />
</form>
</body>
</html>

And then I have an event to fileUpload1 Control: protected void Button6_Click(object sender, EventArgs e) { FileUpload1.SaveAs("D:\\a.txt"); } I ran the project from virtual server of ASP.NET, it worked well. But when I published it to IIS server, it threw that error. Thanks,

So your computer IS where IIS is running, and therefore is the server, right ?

Published it how ? Is IIS running on your local machine ?

If you answered my questions, I'd understand what your situation is, and I'd be able to give you a definitive answer. Is IIS running on your desktop, or on a remote computer ? Where did you publish your site to ?

Yes, I installed IIS into Windows XP on my personal computer.

Yes, IIS is running on my local machine. After creating a ASP.NET project in Visual Studio 2008 and writing code as I mentioned above, then I compiled the project, clicked right mouse on it and selected "Publish Website". Then I copy published files to a folder example (a subfolder of C:\Inetpub\wwwroot). Finally, I ran IE and fill in the address: http://localhost/example/default.aspx, clicked button_6, and got the error. Thanks,

I believe that the web server that's built in to visual studio doesn't enforce the sort of security that IIS does, simply because no-one is going to run a live website with it. Imagine if my site is on a web host that runs a lot of other sites. They are probably all going to be folders under the IIS root. So, if I were to write code that looks for files with a path starting in a .., I could try to read files that belong to another site. That's just one reason why IIS doesn't let you read or write above the root of the web application.
