Mimic AD in a TreeView through C#

What I'm trying to do is query our Domain Controller for all of the Active Directory objects and mimic that view in a C# TreeView. The code I attached below ~works~ but it takes forever to load and hogs up system resources. Is there a simpler way to do this? I just need to make the TreeView look exactly like AD (Ou's, users' computer's, etc). Is there a better way to do this than below?


private static TreeNode RecursiveComputeLeafNodes(String ou, TreeNode nodes)

        {

            DirectoryEntry entry = new DirectoryEntry();

            if (ou.Equals(""))

                entry = new DirectoryEntry("LDAP://dc=corp,dc=pizzagalli,dc=com");

            else 

                entry = new DirectoryEntry(ou);

            //DirectorySearcher mySearcher = new DirectorySearcher(entry);

            //mySearcher.Filter = "(objectClass=computer)";

            foreach (System.DirectoryServices.DirectoryEntry child in entry.Children)

            {

                if (child.Properties.Count != 0)

                {

                    TreeNode newTreeNode = new TreeNode(child.Name.ToString().Remove(0,3));

                    nodes.Nodes.Add(RecursiveComputeLeafNodes(child.Path.ToString(), newTreeNode));

                }

                else

                {

                    String treeName = child.Name.ToString().Remove(0, 3);

                    nodes.Nodes.Add(new TreeNode(treeName));

                }

            }

            return nodes;

        }

Probably; I'm not a programmer, but you might have a look at these for starters, as they might keep you from reinventing the wheel:
