    Does anyone know how I could implement something on my LAN to allow me to find out who is logged into what PC's?

    I'm on a site with 1500 PC's at the moment, and I'm looking for something nice and simple to tell me that PC xxxxx has user yyyyy logged into it, or was the last person to log into it. This would give me a better idea of where each PC is when I have a need to find them.

    I've had soem luck doing things manually when I'm able to connect to the PC by looking though the event viewer, but this is not practical on a large scale. Does anyone know how this could be done?

    Maybe even a command that I could use to find out what network port/switch that PC is connected to. I know there must be some way of doing it, but there doesn't seem to be anyone here who's interested in finding out, because they aren't the ones running round looking for the PC's.

    Sometimes, I've had to resort to remotely ejecting the CDROM drive tray to get someone's attention and sending them messages through net send to find out where a PC is.

    I just want it to be easir!

    thnx in advance.

    i was hoping for something free and simple if that's possible. getting money to spend on things like this is impossible.

    Vibe if you know the machine name and you want the loggedo n person curently all you need to do is at a command prompt "nbtstat -a Machine name" It will come back with the machine name and the user currently logged on. I actually wrote a simple batch file that allowed me to find all the people logged onto specific problem machines on our network years ago worked well enough.

    Maybe you need to document your network. I spent last year doing that where I work. I know where every computer is located. I know which Patch Panel they are located on and which switch they are connected to. Use descriptive names for you computers. Building, Room, Cubicle.

    There is a program called NBTscan that will also do what you want it to do. Because most computers have NetBios over Tcp/IP enabled, you can scan an entire range of IP addresses and it will report back what the computer name is and who is logged onto it.

    I don't know of any programs that can tell you what switch port it is hooked up to.

    I just remembered this program. I have always wanted to try this out. There are alot of programs that do this but most of them are not free. It may help you map out and document your network a little better.

    I wrote a script awhile back for this, just ran it again right now still works. I dont think I ever finished it cause it looks like I am using way too many tokens and I didn't bother to consolidate the find strings. In any case it still works, enjoy.

    Go get netusers.exe from optimumx. Cant provide you a like cause the anti-url code is still enabled for my account. Just do a google search for netusers.exe. The exe I have says it was written by the company optimumx.


    Then run something like script below or just use netusers \\machinename


    :start
    echo .
    echo Building file....
    echo .
    echo .

    for /F "usebackq eol=T skip=3 delims=\\ " %%i IN (`net view`) do netusers \\%%i | findstr -v AUTHORITY | findstr -v \--- | findstr -v successfully | findstr -v Connecting >> wru.tmp
    for /F "tokens=1,2,3,4,5,6,7,8,9,10,11,12,13,14 usebackq delims= " %%k IN (`type wru.tmp`) do (
    rem echo k %%k l %%l m %%m n %%n o %%o p %%p q %%q r %%r s %%s t %%t u %%u v %%v w %%w x %%x
    if '%%k' == 'Current' echo 
    if '%%q' NEQ '' echo %%q
    if '%%k' NEQ 'Current' if '%%k' NEQ 'Error' if '%%k' NEQ 'The' echo %%k
    )

    :end
    if exist wru.tmp del wru.tmp

    I think NBTscan will do a much better job then your script, but that is just my opinion.

    Code:
    C:\nbtscan>nbtscan 192.168.0.100-200
    Doing NBT name scan for addresses from 192.168.0.100-200
    
    IP address       NetBIOS Name     Server    User             MAC address
    ------------------------------------------------------------------------------
    192.168.0.119    SQUASH           <server>  SQUASHMAN        12-34-ba-c0-52-32
    192.168.0.153    BUMBLE-BEE       <server>  BUMBLE-BEE       00-0f-1f-b3-b5-89
    
    C:\nbtscan>

    Neat! Gimme!

    No hard feelings about this script, like I said I wrote that at least 3 years ago.
