How can you find out who has logged into a NT/2000 computer. If you have the workstations set up not to cash any accounts then they have to authenticate at the domain controler which will do the logging. BUT I'm suspecting one of our users has made himself local Admin... therefore how can I find out who was logged in and when localy.
Do you have netbios enabled?
If so... try
nbtstat -a x.x.x.x
nbtstat -a hostname
Should report back who is logged in... as well as services listed and domain names.
http://jcifs.samba.org/src/docs/nbtcodes.html is a list of the netbios hex codes... so you know what you're looking at.
excellent link but
what i ment was who was logged in (let's say) yesterday ... where are the records of that kept
Unless you have the auditing enabled.. then nope.
I take it that from your last post that it isn't enabled.
You might be able to look at the system and application logs and to determine if system changes were made, but it won't give you the username of who made the changes...
One thing to keep in mind is that Windows Events are easily erased as Windows does not have a native syslogd component. If someone is slick enough, they can delete the logs and you'll be out of luck.
is it possible to erace Widows logs only if you have Administrative priviledges or is there a know vulnerability which will enable regular users to do that
It's possible to delete the logs if you have admin rights. If you are on a domain you can enable auditting at the domainlevel. This unfortunately wouldn't log local logons on a workstation.Quote:

Use usermanager to check the privs on that workstation and switch on auditting. You can audit logon/logoff and user and group management and check the logs on a regular basis.
It's easy to check the logs using dumpsec from somarsoft.
Why not write a program which scans all the workstations and records the membership of the Administrators group
Better still, look for anybody except "Administrator" and "Domain Admins" who's in it.
I don't believe such a program would be difficult to write using ADSI and (for example) VBscript in the WSH.
Then you could run that program periodically.
If netbios is enable try Net command....
Especially try ......
net sessions
This would list all the active sessions on ur PC... But this works on the moment...
If u want to record the logins... I feel u could also try central loginng servers..incase u fear that the logfiles could be deleted from local PC... Normally the central Logging servers have inbuilt security to address the above issues.....

Also, if/when you do enable Security auditing, it will still place another entry (by default) in the Security Log when they clear the log. There are ways around this, of course, but you may not be dealing with someone that knows that.
If you are using a Windows 2000 domain, then you can enable auditing as a GPO in AD so that you don't have to touch every machine.
i have "Active Network Monitor" on my laptop, so if i plug the LAN cable on laptop , i could find out who log in my network.
It is not only tell me who log in , but i can find out what they are doing.
u can download the programm for free.
