Retrieve Username of User on Remote Computer

[Pc_Madness]

Hey guys, looking for a way to get the username of a user on a remote computer on a network of WinXP machines, anyone know how?

Basically my plan is scan my class room to get everyones usernames, and then when I get net send spammed I'll know who it came from.

I've had a try of a few examples on here, but I'm not 100% sure if they're what I'm after.

Thanks inadvance.

Hey there PC

This may be a place to start. I use it to load a ComboBox in my NetSend app:

Private Sub Load_Users()
Dim objDomain As Object
Dim objUser As Object
 
On Error GoTo Err_Handler
 
    Set objDomain = GetObject("WinNT://" & Environ$("USERDNSDOMAIN"))
    Set objUser = GetObject(objDomain.Schema)
 
    objDomain.Filter = Array("User")
 
    For Each objUser In objDomain
        cboUsers.AddItem objUser.Name
    Next
 
    Set objDomain = Nothing
    Set objUser = Nothing
 
Exit Sub
 
Err_Handler:
 
    If Not (objDomain Is Nothing) Then Set objDomain = Nothing
    If Not (objUser Is Nothing) Then Set objUser = Nothing
 
    MsgBox "Description: " & Err.Description & vbCrLf & _
        "Number: " & Err.Number, vbInformation + vbOKOnly, App.Title & " - Error"
 
End Sub

Its Robert the Bruce! I haven't seen you in a while!

Yeah, that'll come in handy.

It seems that I might need to be an adminstrator to get the username of a remote computer. Most of the examples seem to work for my computer, but if I change it to another computer, I get an error.

This might help steer you in the right direction...not sure where to go with it but

if you go to search:
pick computers
the enter the computer name in the network..it will return the user name

not sure how you could do this in VB

[Pc_Madness]

Obtaining Workstation User Logon Information

That example seems to work, but it returns all users that have logged on for a while it seems, but it seems to list the current user last.

Edit: I guess theres a problem though that it won't be able to tell you if someone is logged onto the computer or not.

Dear Brute Fox,
Why i can't run your code? I get the error : Run-time Error(-2147463168) Automation Error when i tried to compile it. Do i need to add any references?

dglienna, did you not see the following in the code you posted?

Oops. I have it on my system, but I didn't read the exclusions. This has become a sore point. i tried to link to it the other day, but it was just the same link that PC Madness had in the first post, and the thread was removed. I asked if I should have posted the code, and was told "After I tested it to see if it worked."
It says that I can use it in my own application, so by creating a form and a few controls makes it my own.

Does that mean that I can post it?

- P C - It's the 5th one on the page.

No you cant without permission.

Best thing to do is to link to the page I suppose?

[dglienna]

I tried that yesterday, and was blasted because it was the same link that PC posted when he started the thread. I clicked the link that was five links down on the posted page, and the link was the same! Now I posted it and was blasted again.

Nope. What OS are u using?

Well I am late getting into this one but if its a duplicate link then there is no point posting it.

If you find something else thats worthy then post it if its legal.

[dglienna]

He obviously linked to the page that had all of the links, but no particular program, and I tried to link to a link that was linked to. The page that I tried to link to HAD the code that I then tried to post on it.


IT IS THE FIFTH LINK ON THE PAGE.

[RobDog888]

Chill, David. You dont have to yell! I know its the fifth link on the page. I was referring to you posting a different link that
points to a different article or code sniplette. There is no point in posting a direct link to the same on in the original
first post.

[dglienna]

My point is that I didn't realize it pointed to the first page and not the second.
There is no way to link to the correct page. That's why I yelled. Not to you, but to PC Madness, so he can find it.

[RobDog888]

Regardless, its not that hard to say PC_Madness, look at the 5th link on that page? You did it on an earlier post.
I dont appreciate yelling, no matter who its directed at.

This is what you should have done - Enumerating the User List and Obtaining User Info

[dglienna]

That's what I thought that I was doing. I keep forgetting the I have a copy link in Fx. That is the solution. Sorry about losing my cool. It's just been hard helping this time.
