Get a list of all UNC shared folders on a local network server

I'm trying to get a list of all shared folders available on a local intranet server.

The System.IO.Directory.GetDirectories() works fine for a path like \\myServer\myShare, however I'm getting an exception for a path like \\myServer:

Unhandled Exception: System.ArgumentException: The UNC path should be of the form \server\share.

Is there a way to get a list all shared folders for a server? Ultimately I'm looking for a method that can handle both scenarios based on a given path - returning a list of all shares for a given server and returning a list of all subdirectories for a given network shared folder.

    private DataTable GetSharedFolderAccessRule()
    {
        DataTable DT = new DataTable();

        try
        {
            DT.Columns.Add("ShareName");
            DT.Columns.Add("Caption");
            DT.Columns.Add("Path");
            DT.Columns.Add("Domain");
            DT.Columns.Add("User");
            DT.Columns.Add("AccessMask");
            DT.Columns.Add("AceType");

            ManagementScope Scope = new ManagementScope(@"\\.\root\cimv2");
            Scope.Connect();
            ObjectQuery Query = new ObjectQuery("SELECT * FROM Win32_LogicalShareSecuritySetting");
            ManagementObjectSearcher Searcher = new ManagementObjectSearcher(Scope, Query);
            ManagementObjectCollection QueryCollection = Searcher.Get();

            foreach (ManagementObject SharedFolder in QueryCollection)
            {
                {
                    String ShareName = (String) SharedFolder["Name"];
                    String Caption   = (String)SharedFolder["Caption"];
                    String LocalPath = String.Empty;
                    ManagementObjectSearcher Win32Share = new ManagementObjectSearcher("SELECT Path FROM Win32_share WHERE Name = '" + ShareName + "'");
                    foreach (ManagementObject ShareData in Win32Share.Get())
                    {
                        LocalPath = (String) ShareData["Path"];
                    }

                    ManagementBaseObject Method = SharedFolder.InvokeMethod("GetSecurityDescriptor", null, new InvokeMethodOptions());
                    ManagementBaseObject Descriptor = (ManagementBaseObject)Method["Descriptor"];
                    ManagementBaseObject[] DACL = (ManagementBaseObject[])Descriptor["DACL"];
                    foreach (ManagementBaseObject ACE in DACL)
                    {
                        ManagementBaseObject Trustee = (ManagementBaseObject)ACE["Trustee"];

                        // Full Access = 2032127, Modify = 1245631, Read Write = 118009, Read Only = 1179817
                        DataRow Row = DT.NewRow();
                        Row["ShareName"]  = ShareName;
                        Row["Caption"]    = Caption;
                        Row["Path"]       = LocalPath;
                        Row["Domain"]     = (String) Trustee["Domain"];
                        Row["User"]       = (String) Trustee["Name"];
                        Row["AccessMask"] = (UInt32) ACE["AccessMask"];
                        Row["AceType"]    = (UInt32) ACE["AceType"];
                        DT.Rows.Add(Row);
                        DT.AcceptChanges();
                    }
                }
            }
        }
        catch (Exception ex) 
        {
            MessageBox.Show(ex.StackTrace, ex.Message);
        }

        return DT;
    }

Here's a technique that uses System.Management (add a reference to this assembly):

using (ManagementClass shares = new ManagementClass(@"\\NameOfTheRemoteComputer\root\cimv2", "Win32_Share", new ObjectGetOptions())) {
    foreach (ManagementObject share in shares.GetInstances()) {
        Console.WriteLine(share["Name"]);
    }
}

Appropriate permissions are required.
