**Ubimia** · 04-02-2009

Hi,
I am having this problem with ASP.NET application i have developed with Visual Studio, Windows Server 2003, VB.NET, Framework 2

The error i am getting is while i am trying to access the files(binary files stored in C:\ in win 2003) through the network drive map.

Code:

System.IO.DirectoryNotFoundException: Could not find a part of the path
'Z:\filename.ext'.
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)
at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess
access, FileShare share)
at Service.GetPersonObject(Int32 IdPerso) in
C:\Inetpub\wwwroot\WebServicePerson\WebServicePerson\App_Code\Service.vb:line
1152

Please guide me!

Please try to give the rights to ASP user.

Hope this solves the problem.

You can also try to impersonate the application

Well thanks for the reply!
I tried both the suggestions but the problem still persists.

Code:

<identity impersonate="true" userName="user" password="pwd"/>

i'm trying to access these files through a map drive to test
access with Webservices through the network layer. If we make it only
with a shared folder, does windows use the same implementation of
network layer?

Hey

This is the account where ASP.NET runs in windows server 2003.

Code:

YourMachineName\Network Service

Give the necessary file access permissions to that account, that it can access your network drive

**bobmitch** · 04-02-2009

if you are impersonating, it's the account which
ASP.NET is impersonating which needs the access permissions.

The problem is only about giving the permission to the correct account for ASP.NET application

Run this code to find out the identity!

Code:

Identity.aspx

<%@ Page Language="VB" %>
<%@ Import NameSpace = System.Security.Principal %>
<script runat="server">
Sub Page_Load()
Dim tmp As String = WindowsIdentity.GetCurrent.Name()
Label1.Text = tmp
End Sub
</script>
<html>
<head>
<title>WindowsIdentity.GetCurrent.Name()</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Label ID="Label1" Runat="server" Text="Label"></asp:Label>
</div>
</form>
</body>
</html>
