How to monitor windows users

[Mads Rasmussen <mads cit com br>]

Hi there,

This may be somewhat off topic but I am rather lost

I would like to see who is currently locked on to our network, the problem is 
that its a win nt network and the nt administrators don't know how to do this 
so the monkey is on me.

I was able to find out who is logged on a nt machine to the domain using the 
nmblookup tool from the samba distro.

With nmblookup -A machine.localdomain I get a list

received 8 names
        ADA             <00> -         B <ACTIVE>
        CIT             <00> - <GROUP> B <ACTIVE>
        ADA             <03> -         B <ACTIVE>
        ADA             <20> -         B <ACTIVE>
        VIVIANPT        <03> -         B <ACTIVE>
        CIT             <1e> - <GROUP> B <ACTIVE>

But it's not that good and doesn't work every time (vivianpt is the user)

Do anyone here know of a better tool to query the windows domain server?

Thanks in advance!

Regards,

Mads
