Try the following console program. It is probably not the best but I think it will work. I assume you can use this as a sample. using System; using System.IO; using System.DirectoryServices; using System.Diagnostics; namespace _70570 { class Program { static StreamWriter sw; static void Main(string[] args) { try { sw = new StreamWriter(70570.txt); } catch (Exception ex) { Console.WriteLine(Output file open error: {0} ex.Message); return; } DirectoryEntry de = null; try { de = new DirectoryEntry(WinNT:); foreach (DirectoryEntry Domain in de.Children) { sw.WriteLine(Domain: {0} Domain.Name); foreach (DirectoryEntry Computer in Domain.Children) { sw.WriteLine(	Computer: {0} Computer.Name); if (GetProperty(Computer OperatingSystem)) { foreach (DirectoryEntry User in Computer.Children) { if (GetProperty(User UserFlags)) sw.WriteLine(		User: {0} User.Name); User.Close(); } } Computer.Close(); } Domain.Close(); } } catch (Exception ex) { Console.WriteLine(Exception: {0} ex.Message); sw.WriteLine(Exception: {0} ex.Message); } if (de != null) de.Close(); sw.Flush(); sw.Close(); } private static bool GetProperty(DirectoryEntry de string p) { String v = null; try { v = de.Properties[p].Value.ToString(); } catch (Exception ex) { return false; } sw.WriteLine(		{0}: {1} p v); return true; } } }
