Coding Addict Some people think that make a program work is just technical issues, logics, mathematics, and to memorize the number of instructions. Sometimes in fact they think that this is just a typing job, whereas thinking deeply. They forget that right-brain work there. Sorry guys, it's not (only) about money, because it's about sense of life.

in our case, we are using Specific user for all request so we are entering username as a "IUSR_WEBSERVER" and password we can also implement Impersonate using Code, but I am not describing this here, you can check the Full Details about "How to Implement Impersonate through code" by click on this link http://support.microsoft.com/kb/306158 To access network file we can not map network drive and use it, but instead of map network drive, we have to use UNC (Universal Naming Convention) So use like this:"\\Fileserver\FolderName\Files\File1.txt" Instead of z:\Folder\Files\file1.txt Here is code to retrieve network file and display on web page. Dim strPath As String = "file://FILESERVER/TempFolder/FileName.pdf">\\FILESERVER\TempFolder\FileName.p df If FileIO.FileSystem.FileExists(Trim(strPath)) Then Response.WriteFile((strappath)) Else 'Show message " File not found" End If Conclusion
So by using this article we can access network files and folder, there are also other way to implement this, but this is depend on users choice. Hope this article will help you.... In case of any Problem or Issues , please feel free to post message.

How to access shared folder or network resource in ASP.Net Source: http://support.microsoft.com/kb/842789
You receive a "logon failure: unknown user name or bad" error message while accessing remote security-enhanced resources from an ASP.NET application SUMMARY
This article discusses the behavior of accessing a remote security-enhanced resource from a Microsoft ASP.NET application. The article contains the following workarounds for this behavior: •
In the Machine.config file, change the userName attribute and the password attribute of the processModel element.
•
Run the application under the identity of a user who has permissions to the remote security-enhanced resource by using the impersonation element in the Web.config file.
•
Change the password of the ASPNET user account to some known value, and then create the same ASPNET user account that uses the same password on the remote computer.
Access the remote security-enhanced resource by using a COM component that is running • under the security context of a user account that has permissions to the remote securityenhanced resource. •
Run the part of the code that is accessing the remote security-enhanced resource under the identity of a user who has permissions to the remote security-enhanced resource.
Call the WNetAddConnection2 function to open the connection to the remote security• enhanced resource, and then map the local drive to the remote security-enhanced resource in the code. This article also includes detailed steps to reproduce the behavior. Back to the top SYMPTOMS
When you access remote security-enhanced resources from an ASP.NET application, you may receive the following error message: Logon failure: unknown user name or bad password. Back to the top CAUSE
By default, an ASP.NET application runs under the security context of an ASPNET user account. The ASP.NET application accesses the remote security-enhanced resource by using the ASPNET user account when the following conditions are true: • When the impersonation feature is not turned on for the ASP.NET application •
When the authentication method in Microsoft Internet Information Services (IIS) is set to anonymous access
However, the ASPNET user account may not have permissions to access the remote securityenhanced resource. Back to the top WORKAROUND
To work around this behavior, use one of the following methods: • Use the Machine.config file • Use the impersonation feature in the Web.config file • Change the password of the ASPNET user account • Use a COM component to access the remote security-enhanced resource • Use the code impersonation feature • Call the WNetAddConnection2 function in your code Back to the top
Use the Machine.config file Change the userName attribute and the password attribute in the processModel element of the Machine.config file to the credentials of a user who has access to the remote securityenhanced resource. After you make this change, restart the computer. Note and are placeholders for the credentials of a user who has access to the remote security-enhanced resource. Important Do not to store clear-text passwords in the Machine.config file. Instead, use the Aspnet_setreg.exe utility to store encrypted passwords in the registry. For additional information about how to use the Aspnet_setreg utility, click the following article number to view the article in the Microsoft Knowledge Base: 329290 (http://support.microsoft.com/kb/329290/) How to use the ASP.NET utility to encrypt credentials and session state connection strings When you use this method, the change is global. This is a drawback because other Web applications and other Web services that are running on the computer where you make the change will also run in this new security context. However, this is not the case for Microsoft Internet Information Services (IIS) 6.0 on Microsoft Windows Server 2003 because IIS uses application pools for Web applications and for Web services. Each application can run in its own application pool. Each application pool can be configured for the user name field and the password field. You can set this configuration under the security context of the worker process in the application pool where the application runs. If you change the user account under the security context that the ASP.NET worker process is running in, you may also have to grant the correct permissions to that user account on some folders on the Web server to make the worker process run successfully. For more information about how to create a custom account to run ASP.NET applications, visit the following Microsoft Developer Network (MSDN) Web site: http://msdn2.microsoft.com/en-us/library/aa302396.aspx (http://msdn2.microsoft.com/enus/library/aa302396.aspx) Back to the top
Use the impersonation feature in the Web.config file You can set fixed identities that have access to the remote security-enhanced resource for specific virtual directories by using the following setting in the Web.config file for your application. Note and are placeholders for the credentials of a user who has access to the remote security-enhanced resource. Important Do not to store clear-text passwords in the Machine.config file. Instead, use the Aspnet_setreg.exe utility to store encrypted passwords in the registry. For additional information about how to use the Aspnet_setreg utility, click the following article number to view the article in the Microsoft Knowledge Base: 329290 (http://support.microsoft.com/kb/329290/) How to use the ASP.NET utility to encrypt credentials and session state connection strings You can use one of the following accounts for impersonation: • A domain account • A "mirrored" local account A "mirrored" local account has a matching user name and a matching password on two computers. You must use this account if the computers are in separate domains and do not have a trust relationship.

Change the password of the ASPNET user account By default, the ASP.NET worker process (Aspnet_wp.exe) runs under the ASPNET user account. The ASPNET user account is located under Local Users and Groups. This account has a strong password that is secured in the Local System Authority (LSA). To use this method, follow these steps: 1 In Local Users and Groups on the Web server, change the ASPNET account password to . a known value. Replace the credentials in the processModel element in the Machine.config file with the following. Note is the placeholder for the password that you have assigned to the ASPNET user account. 3 On the remote computer, create an account that is named ASPNET and that has the same . password as the ASPNET user account on the Web server. 4 Add the ASPNET account on the remote computer to the Access Control List (ACL) of . the security-enhanced resource.

Use the code impersonation feature By default, the ASP.NET worker process (Aspnet_wp.exe) runs under the security context of the ASPNET user account. To use this method, the user account under the security context that the ASP.NET worker process (Aspnet_wp.exe) runs in must be part of the "Act as part of the operating system" policy. You can use Local Security Policy in the Windows Administrative Tools to add the ASPNET user account to the "Act as part of the operating system" policy. Note To use this method, you must maintain a list of user names and their corresponding passwords in your application. Because you are using those user names and passwords to connect to the remote security-enhanced resources from the code, you must make changes in your application when these user names or their corresponding passwords change. 1 Start Microsoft Visual Studio .NET . 2 On the File menu, point to New, and then click Project.
