Your computer, your Internet service provider, or the specified directory service may be disconnected. Check your connections and try again. Operations Error --------------------------- OK --------------------------- Is that exception because of this error or it is something else suggest me how can I sole this . This is my code: ADPath = "LADP://192.168.1.15”; DirectoryEntry oDE; oDE = new DirectoryEntry(ADPath, ADUser, ADPassword, AuthenticationTypes.Secure); try { // Change the password. oDE.Invoke("ChangePassword", new object[]{strOldPassword, strNewPassword}); } catch (Exception excep) { Debug.WriteLine("Error changing password.
