Hi guys!
I have a code:
String Lastlogon(string username, string domain)
{
try
{
{
DirectoryContext context = new DirectoryContext(DirectoryContextType.Domain,domain);
DateTime latestLogon = DateTime.MinValue;
string servername = null;
DomainControllerCollection dcc = DomainController.FindAll(context);
foreach (DomainController dc in dcc)
{
DirectorySearcher ds;
using (dc)
using (ds = dc.GetDirectorySearcher())
{
ds.Filter = String.Format("(sAMAccountName={0})",username);
ds.PropertiesToLoad.Add("lastLogon");
ds.SizeLimit = 1;
SearchResult sr = ds.FindOne();
if (sr != null)
{
DateTime lastLogon = DateTime.MinValue;
if (sr.Properties.Contains("lastLogon"))
{
lastLogon = DateTime.FromFileTime((long)sr.Properties["lastLogon"][0]);
}
if (DateTime.Compare(lastLogon, latestLogon) > 0)
{
latestLogon = lastLogon;
servername = dc.Name;
}
}
}
}
return latestLogon.ToString();
}
}
catch (Exception)
{
err = true;
return null;
}
}as a domain I provide "woobie.net"
as an user I provide Login "jlennon"
Unfortunately I always receive a message "server not operational"
Anyone knows what can be wrong with that code?
