With one small adjustment, the script in my previous post can be used as a function to list all properties and subproperties of any variable in Windows Powershell. It’s a great way to explore Powershell and create scripts. I used to do the following procedure very often:
$a = Get-Process #For [...]
UPDATE: Fixed the script to also recurse through arrays. It only gets the first item in the array. That’s for a good reason. Else you’ll get millions of items!
Wow! This was quite a challenge. But I did it!
Inspired by my scripts Create a Directory Tree with Powershell and Listing AD [...]
If you have been trying out the VMware VI Toolkit for Windows Powershell, you have probably noticed. You have to disconnect (disconnect-viserver) each session you set up to the VI Server (connect-viserver), or it will linger for eternity (or until the next reboot at least). That’s why I always [...]
I was playing around with PSDrives when I decided to write this script. It recurses through (part of) a PSDrive and shows the items it finds in a simple tree view.
The fun part is that it works on any PSDrive!
Show-Tree D:\scripts will show subdirectories and files in a tree; Show-Tree HKCU:\ will [...]
PeetersOnline.nl has been updated, restyled, pimped, tricked out… whatever you want to call it.
So, if you are following me via RSS, please come take a look at the new site design.
If you have any remarks or experience any issues, please leave a comment.
So much for visuals. Back to the scripting!
Check out this oneliner/function! Provide a computer name and it will return the logged on users.
function Get-MyLoggedOnUsers
{
param([string]$Computer)
Get-WmiObject Win32_LoggedOnUser -ComputerName $Computer | Select Antecedent -Unique | %{“{0}{1}” -f $_.Antecedent.ToString().Split(‘”‘)[1], $_.Antecedent.ToString().Split(‘”‘)[3]}
}

The Quest Active Directory Cmdlets are very useful in getting AD group members. The only thing I was missing, was a -Recursive parameter. So I created this script.
You feed it AD Group Names as a parameter, and it will return a nice tree view of all members and subgroups and their members and so [...]
Of all the vSwitch properties, the Offload Policy settings are the most obscure. You can’t even view them through the GUI. You can see them in the /etc/vmware/esx.conf file, or using the Powershell VI Toolkit, if you know how to use this command:
((Get-VMHostNetwork ESXSERVER | Get-View).NetworkConfig.vSwitch | Where [...]
Now that you can list shares, how about something a bit more challenging?
Let’s take a look at share permissions. I tried using subinacl.exe to get these for a remote share. But it turns out that it does not always give trustworthy results. It showed read permissions for a share with Read and Change permissions. [...]
Here’s a handy little function I wrote for enumerating all shares on a remote server:
function Get-MyShares
{
param([string]$Server)
$Shares = Get-WmiObject -Class Win32_Share -ComputerName $Server
$output = @()
ForEach ($Share in $Shares)
{
$fullpath = “\\{0}\{1}” -f $server, $share.name
Add-Member -MemberType NoteProperty -InputObject $Share [...]
