I would like to a) programatically and b) remotely find out the last date/time that a user successfully logged into a Windows machine (via remote desktop or at the console). I would be willing to take any typical windows language (C, C#, VB, batch files, JScript, etc...) but any solution would be nice.
Try this:
public static DateTime? GetLastLogin(string domainName,string userName)
{
PrincipalContext c = new PrincipalContext(ContextType.Domain,domainName);
UserPrincipal uc = UserPrincipal.FindByIdentity(c, userName);
return uc.LastLogon;
}
You will need to add references to using using System.DirectoryServices and System.DirectoryServices.AccountManagement
EDIT: You might be able to get the last login Datetime to a specific machine by doing something like this:
public static DateTime? GetLastLoginToMachine(string machineName, string userName)
{
PrincipalContext c = new PrincipalContext(ContextType.Machine, machineName);
UserPrincipal uc = UserPrincipal.FindByIdentity(c, userName);
return uc.LastLogon;
}
You can use DirectoryServices to do this in C#:
using System.DirectoryServices;
DirectoryEntry dirs = new DirectoryEntry("WinNT://" + Environment.MachineName);
foreach (DirectoryEntry de in dirs.Children)
{
if (de.SchemaClassName == "User")
{
Console.WriteLine(de.Name);
if (de.Properties["lastlogin"].Value != null)
{
Console.WriteLine(de.Properties["lastlogin"].Value.ToString());
}
if (de.Properties["lastlogoff"].Value != null)
{
Console.WriteLine(de.Properties["lastlogoff"].Value.ToString());
}
}
}
