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

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>
<authenticati on mode="Windows"/>
<identity impersonate="tr ue"/>
</system.web>
..aspx.cs snippet (from Page_Load event)
using (System.Managem ent.ManagementC lass exportedShares = new
System.Manageme nt.ManagementCl ass("Win32_Shar e"))
{
System.Manageme nt.ManagementOb jectCollection shares =
exportedShares. GetInstances();

foreach (System.Managem ent.ManagementO bject 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.Manageme nt.ManagementOb jectCollection shares =
exportedShares. GetInstances(); . The exception details are:
System.Manageme nt.ManagementEx ception: 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).

this setup won't work. the web service is running with a secondary credital,
so it can not access a network resource (one hop rule). you have three
options

1) set the web site to basic authenication
2) switch to activce directory and kerberos.
3) remove <identity impersonate="tr ue"/> and give the app pool an account
with network permissions.

I have been ignoring this problem for a few weeks now, but it's becoming a bit annoying not to mention unproductive. Here it goes: I compile my project with no errors. Then after I debug/run it, I get the runtime error noted at the end of this message. If I re-compile (without any changes) and re-run, then my project will run OK. This behavior is very consistent. Another words, the only way I can run an ASP.NET application is if I...

When trying to use the function CreateDirectory on my local machine everything works fine but when I upload the page to my webhost I get an issue that it can't find path on D:\, though D:\ is what my website is found on.

My question is what is the correct approach to solve this...

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

The below code is what I'm using to upload JPG's to a Shared folder on my web server. The folder \\GLSDBS03\Entry$ is outside my Web folder. When using FileUpload, and trying to save the JPG, I get a "Failed to map the path '/GLSDBS03/Entry$'" error. I'm open to suggestions or a better idea.

Here is a nasty issue that has been giving me grief for the last couple days. This requires good knowledge of IIS, MSXML, and Windows/NTFS permissions. We have an existing ASP (VBScript) app hosted on IIS 6.0 (W2K3). We need to restrict access to specific users within our company network. To reduce development effort I figured the easiest solution was to enable Integrated Windows Authentication. However once I enable IWA and disable...
