I have performed an "LDAP://" query to get a list of computers within a specified OU, my issue is not being able to collect just the computer "name" or even "cn".

        DirectoryEntry toShutdown = new DirectoryEntry("LDAP://" + comboBox1.Text.ToString());
        DirectorySearcher machineSearch = new DirectorySearcher(toShutdown);
        //machineSearch.Filter = "(objectCatergory=computer)";
        machineSearch.Filter = "(objectClass=computer)";
        machineSearch.SearchScope = SearchScope.Subtree;
        machineSearch.PropertiesToLoad.Add("name");
        SearchResultCollection allMachinesCollected = machineSearch.FindAll();
        Methods myMethods = new Methods();
        string pcName;
        foreach (SearchResult oneMachine in allMachinesCollected)
        {
            //pcName = oneMachine.Properties.PropertyNames.ToString();
            pcName = oneMachine.Properties["name"].ToString();
            MessageBox.Show(pcName);
        }

Help much appreciated.
