string primarylogon = box1.Text.ToString().Trim();
//box1.Text = Samaccount Name (LANID)
DirectoryEntry oroot = new DirectoryEntry("LDAP://Domainname");
DirectorySearcher search = new DirectorySearcher(oroot);
search.Filter = String.Format("(SAMAccountName={0})", primarylogon);
search.PropertiesToLoad.Add("SAMAccountName");
search.PropertiesToLoad.Add("givenName");
result = search.FindOne();
if (result == null)
{
 lbl1.Text = "No such LAN ID found!Please re-enter the LAN ID";
