REPOST: Error Using WMI to Get List of Shared Folders on the Server

[lecnac]

Sorry for the repost. I must have done something wrong when I tried to post
my reply (I can't seem to find it).

Anyway, I'd really appreciate any help that anyone could provide. My issue
is quickly becoming more and more urgent.

I've tried the code below using the server's local Administrator user name
and password. This gets me past the Access denied error but gives me a User
credentials cannot be used for local connections error.

ManagementScope ms;
ManagementClass mc;

ms = new ManagementScope();
ms.Options.Username = "username";
ms.Options.Password = "password";
ms.Options.Authentication = Authentication.PacketPrivacy;
ms.Path = new ManagementPath("//server/root/CIMv2");

mc = new ManagementClass(ms, new ManagementPath("Win32_Share"), null);
Maybe another thought... Should I not use WMI to try to get a list of
shared folders on the server? Should I use something else? If so, what?

Here's some details:

Server and workstation both in the same workgroup
Logged into server as local Administrator
Logged into workstation as a local user that is only in the Users group
The local user on the workstation is also defined with same name and
password on the server (and only in the Users group on the server)
Server is Windows Server 2003 running IIS 6.0
Workstation is Windows XP Professional
ASP.NET 2.0 (C#) web site
Web.config snippet
<system.web>
<authentication mode="Windows"/>
<identity impersonate="true"/>
</system.web>
.aspx.cs snippet (from Page_Load event)
using (System.Management.ManagementClass exportedShares = new
System.Management.ManagementClass("Win32_Share"))
{
System.Management.ManagementObjectCollection shares =
exportedShares.GetInstances();

foreach (System.Management.ManagementObject share in shares)
{
// Get shared folder information, for example
Response.Write("Name: " + share["Name"].ToString());
}
}
Open IE and navigate to the web site on the server (using
http://servername/website). I get an access denied error. The exception is
thrown on the line: System.Management.ManagementObjectCollection shares = exportedShares.GetInstances();. The exception details are:
System.Management.ManagementException: Access denied

What I'm trying to do is list all the shared folders on the server on a
page. However, when I run this application from a different computer, I
get
the access denied error.

** How can I get a list of shared folders on the server no matter what
computer is accessing the ASP.NET application?
** What do I need to do differently to get the above code and scenario to work?

** Is there a better way of doing this than WMI? If so, what?
P.S., On the server, I tried give the local user full WMI permissions
through Computer Management, and it didn't work (nothing changed; I still got the access denied error).

You should not specify any credentials for "local" connections, the current
users security token will be used as access token. Note that you should not
specify the local server name in the management path, your code should look
like this:
ManagementClass mc;
ms.Path = new ManagementPath("./root/CIMv2");
using(mc = new ManagementClass(ms, new ManagementPath("Win32_Share"),
null))
{
....
}
