list wmi namespace

Last week I published an article about how to set your host reserves in VMM Manager. I deliberately left off with a manual task. Changing the host reserves only affects new hosts added to your VMM environment. What about the ones that are already there? You had to manually change them.

Using PowerShell on a client that has VMM Manager installed on it, you can change the Host Reserves of all Hosts that are already on the system

Open PowerShell (You must do this on a client that has VMM Manager installed on it)
Type Add-PSSnapin Microsoft.SystemCenter.VirtualMachineManager and press Enter.
This adds in cmdlets that are specific to Virtual Machine Manager.
Now type Get-VMHost | Select-Object ComputerName, CPUPercentageReserve, NetworkPercentageReserve, DiskSpaceReserveMB, MaxDiskIOReservation, MemoryReservationMB and press Enter.
This will show you the current Host Reserves on each host.

We can use the 5 reservation properties to change the host reservations. For simplicity, we are only going to change the CPU and Network percentage reserves.
Get-VMHost | Set-VMHost –CPUPercentageReserve 25 –NetworkPercentageReserve 35

If we re-execute our first command, we get the following:

How to run GPResult on a remote client with PowerShell

Where did a User’s Account Get Locked Out?

Updated: May 15, 2015 When this article was originally published, two extra carriage returns were add causing the code to malfunction. The code below is correct. My client for this week’s PowerShell class had a really interesting question. They needed to know where an account is being locked out at. OK, interesting. Apparently users hop around clients and forget to log off, leading to eventual lock out of their accounts. The accounts can be unlocked, but are then relocked after Active Directory replication. This problem is solved in two parts. The first one is to modify the event auditing on the network. The second part is resolved with PowerShell. The first part involves creating a group policy that will encompass your Domain Controllers. In this GPO, make these changes. Expand Computer Configuration \ Policies \ Windows Settings \ Security Settings \ Advanced Audit Policy Configuration \ Audit Policies \ Account Management Double click User Account Management C...
