Unable to access folders across two servers.

[Neeba]

Scenario :

1. The Department files to be accessed are present in the File server.
2. The Code is present in a different server with OS being Windows Server
2003.
3. Access to File server happens using ADS Authentication.
4. Code is developed in ASP.NET using VB.NET. (Web.Config file settings are
based on ADS Login; Authentication=Windows ; )
5. Requirement is to display folders and files in a treeview structure.
[Built in functions like GetDirectories and GetFiles returns nothing and
functions related to Kernel Programming like (Private Declare Function
FindFirstFile Lib "kernel32" Alias "FindFirstFileA" (ByVal lpFileName As
String, ByRef lpFindFileData As WIN32_FIND_DATA) As Integer— Returns -1 )]
when executed from Windows Server 2003.
6. The same code works fine without any issues when run locally from an XP
machine.

Hello Neeba,

It happens because on Win2k u are using IIS6, which blocks calls to filesystem
by default - NETWORK SERVICE account restriction
when u run this app under WinXP u are running in IIS5, which allows calls
to filesystem

Solution:
1) grad permition to access filesystem for NETWORK SERVICE, or create special
use (recomended)
2) use IIS5 isolation mode settings in IIS6
