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; } } }
