Reolve IP or DNS on network to NT Username

I am currently working on a LAN monitor. I have a ping sweep that on a period of time check for IP's alive over the network. Now i can resolve this IP to a machine/hostname. But how can i further resolve these into the current user logged on, on that NT machine?? Preferebly not using a crawler or watch dog on the client side please !
It's pretty much like doing sms. But how can it be done on VB?


At the end, with just an IP/Hostname, i want to know some information on who is using a particular NT machine on my network?

regards,
gokula

hello , i saw you problem and if you find the solution of how to find the names of all the computers in the net
i'll thankful.

nbtstat -a <computername> will give you what you want, but you'll have to wade thru other info to get it.

I didn't take a good at it, but there is a recent thread that may help: http://forums.vb-world.net/showthrea...threadid=51806

All my experience (minimal) with NBTSTAT shows me that if you run:

C:>nbtstat -A <ip address> >C:\temp\sometempfile.txt

you will get back the DNS name of the related workstation, the MAC address and the logged in user name. The above command willpipe it out to a text file for later reference.

What I am trying to figure out is why my ShellEx routine will not pipe the information to a text file in the same manner as the exact same command line will do when written at the DOS prompt.

Have you tried creating the command in a bat file and shellexecuting that?
