In the VBScript code, the query on line 12 will fail with a “Table does not exist” error unless “LDAP” is in upper case.

Otherwise, thanks for this, saved me an hour writing it from scratch.

A slightly different way to do it is over a search of the trusted Domains. needed it some time ago to search on different domains in a forrest and fill up objects with the “Domain\\Username” notation …

///
/// Gets All Trusted Domains in the Domain Forrest
///
public Dictionary GetDomains()
{
    SearchResultCollection srCollection;
    DirectoryEntry deRoot = new DirectoryEntry(@"LDAP://eu.infineon.com:389/DC=infineon,DC=com");
            DirectorySearcher deSearcher = new DirectorySearcher(deRoot);
            deSearcher.Filter = ("(objectClass=trustedDomain)");
            deSearcher.PageSize = 1000;
            deSearcher.SearchScope = SearchScope.Subtree;
            srCollection = deSearcher.FindAll();

            //ArrayList DomainList = new ArrayList();
            Dictionary DomainList = new Dictionary();

            foreach (SearchResult se in srCollection)
            {
                string currentDomainName = se.GetDirectoryEntry().Name.ToString();
                string currentNomainFlatName = se.GetDirectoryEntry().Properties["flatname"].Value.ToString();
                currentDomainName = currentDomainName.Replace(".", ",DC=");
                currentDomainName = currentDomainName.Replace("CN", "DC");
                DomainList.Add(currentDomainName,currentNomainFlatName);
            }

            return DomainList;
        }

Hi, thank you for the scripts.
I tried PS and c# codes. They retrieve only one domain in my environment.
But I have 6 domains, if I open my Network Places->Microsoft Windows Networks I see them.
Also, I can retrieve 6 items when I use this code

DirectoryEntry rootEntry = new DirectoryEntry("WinNT:");
foreach (DirectoryEntry child in rootEntry.Children)
{
   listBox1.Items.Add(child.Name);
}

But I’d like ot use LDAP because of WinNT is legacy provider.
Thanks.
