Access Denied to use WMI getting remote resource


I have the access denied on my ASP.NET C# program while deploy my project from my PC (WinXP) to Server 2003
The program works fine on my PC but get access denied on Server 2003.

However the program works fine on Windows Server 2003 while trying to use WMI to get resource from the itsself computer, just has the problem while remoting to other computer.

I did put the permission of all security to "Everyone" on "Windows Managment and Instrustmentation" in Component Service, or even put the ASP.NET account is as a group of Administrators and no help, did I do anything wrong? Thank you.

Here is the stack trace:
[UnauthorizedAccessException: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))]
   System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo) +0

   System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +33
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +5102

Here is some of the code in "Default.aspx"

Protected Sub showUserList(ByVal password As String, ByVal server As String)
        If server = "" Then
            MS = New ManagementScope("\\.\root\cimv2")
            MS.Connect()
            objQuery = New System.Management.ObjectQuery("Select Name from Win32_UserAccount")
        Else
            conn.Username = "administrator"
            conn.Password = password
            MS = New ManagementScope("\\" & server & "\root\cimv2", conn)
            MS.Connect()
            objQuery = New System.Management.ObjectQuery("Select Name from Win32_UserAccount")
        End If
........
End Sub

 I changed the processModel back to machine from system. system runs as
localsystem with high permissions while machine runs as low privilege user
account.

Sorry,  I don't understand that guy meaning, what is the processModel and
where he changed the permission?
Thanks
