How to get the currently logged on user of a remote computer

Any NetAPI which could retrieve the name of user currently logged in on a remote computer.. and the time a remote computer is on for..
?????

I'm not sure about how to use the net API's to do this, but Sysinternal Software has a free utility which can return the logged in user from a remote machine.

You could shell to this prog and send its output to a text file.

The program is called PsLoggedOn and you can get it here: http://www.sysinternals.com/ntw2k/fr...loggedon.shtml

Anybody plz...I need VB code!!

r u the pakistani former wicket keeper ......... in cricket team ........... lol :)

You could use WMI.

Code:

---

Set objWMIService = GetObject("winmgmts:" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_ComputerSystem", , 48)
    For Each objItem In colItems
        RemoteUser = objItem.Username
    Next

Also check out Microsoft's documentation.

Maybe:D

I've used your code ITGuy.. but it's very slow and it doesn't get the username of all computers and moreover it also gives permission denied error...
IT only gives the username of those computers on which i have the administrative rights... (and in our 75 computers i have the administrative rights on only 10:rolleyes::( )
Any ideas?

In a form with a Listbox "Listbox1"
This code is from VBnet..

Thanx Libero....your code is working like a charm.. but what i need is the way to know the currently logged on user name
Thanx again..

Ooops! I did see that now.. :eek:. Sorry!
