Re: Win32_LogicalDisk Not Working Properly

OK, now I see what you are saying. I didn't realize that I was creating an
actual session by doing a WMI query. Just before I do the WMI query with
Win32_LogicalDisk, I do this:

Set colItems = objWMIService.ExecQuery("Select * from
Win32_ComputerSystem",,48)
For Each objItem In colItems
txtResults.Value = txtResults.Value & "Computer: " & objItem.Name & vbCrLf
txtResults.Value = txtResults.Value & "UserName: " & objItem.UserName &
vbCrLf
Next

Which only showed one user - the one that is physically logged in to the
computer, so I was thrown off by that. How would I go about enumerating the
session? I can't seem to find any information regarding that with WMI.
