Tech Ed 2008 - Demo 1 - Administering Windows
Hello Again
Well I’ve delivered my session “Windows, PowerShell and WMI: Unveiling Microsoft’s Best Kept Secret”, and as promised here are the scripts for the Demo’s I used during my session:
Demo 1 – Administering Windows
All these demos are simple command lines that I just typed straight in PowerShell, no need for any fancy scripts.
Basics
The following lines of code show help on how to use the Get-WMIObject cmdlet in PowerShell, how to list all classes in the cimv2 namespace and finally how to use some basic parameters.
|
Get-Help -name Get-WMIObject
Get-Help -name Get-WMIObject –det
get-wmiobject -namespace "root\cimv2" –list
Gwmi -namespace "root\cimv2" –list
Gwmi -namespace "root\cimv2" -class Win32_LogicalDisk
Gwmi -class Win32_LogicalDisk
Gwmi Win32_LogicalDisk
Gwmi Win32_LogicalDisk –computername localhost
$cred = get-credentials
Gwmi Win32_LogicalDisk –credential $cred |
Disks
These lines of code show how to get disk information from a system, identify all the properties and methods of the disk objects that can be used, then uses some properties.
|
Gwmi Win32_LogicalDisk | Get-Member
$disks = gwmi Win32_LogicalDisk –computername localhost
$disks[0].freespace
$disks[0].freespace/1gb
$disks[0].filesystem |
Hotfixes
These lines connect to a system and list all the Hotfixes that have been installed.
|
$hotfixes = gwmi Win32_QuickFixEngineering –computername localhost
$hotfixes | get-member
$hotfixes | format-table Hotfixid |
OperatingSystem
These lines enumerate basic operating system information: the OS version, service pack level and OS architecture type.
|
$os = gwmi win32_OperatingSystem -computername Serverxxx
$os | get-member
$os | format-list caption, CSDVersion,OSArchitecture |
Network Adapter
The following lines modify the IP Address and Subnet Mask of a network adapter using the EnableStatic method.
|
$nics = Gwmi win32_NetworkAdapterConfiguration
$nic = $nics | where{$_.description –like “*XXXXXXXXXXXX*”}
$IPAddress = x.x.x.x
$subnetmask = x.x.x.x
$nic.EnableStatic($IPAddress, $SubnetMask) |
Well that’s the first demo stay tuned for Demo 2 – Administering Servers in Bulk.
Enjoy!
