1. PowerShell Basics

2. o PowerShell is a great way to manipulate server and/or workstation components o It’s geared toward system administrators by creating a more simplified syntax base o PowerShell is more secure than running vbscripts o Quick analysis of various computer specs

3. o Microsoft.NET Framework v2.0 or later o Windows XP/Server 2003 or later o The PowerShell install file (Download)Download o Windows Management Framework (Includes) o Windows Remote Management o Windows PowerShell 2.0 o Background Intelligent Transfer Service (BITS) 4.0

4. o You can use commands that you are familiar with such as CD, PING, IPCONFIG or DIR o There are also some Unix commands that can be used such as LS or MAN (these commands are aliases to the actual PowerShell commands) o Get-Alias will list the preloaded Alias’s and will show you what Cmdlet they are mapped to

5. o The majority of the PowerShell functionality comes from Cmdlet’s o Always in Verb-Noun format and never plural (Get-WmiObject or Get-Process) o Cmdlet’s return objects not text o Retrieve list of Cmdlet’s (Get-Command) o Can tab complete

6. o One of the time savers in PowerShell is giving the user the ability to pipe commands together o Ex. Get-process | select ProcessName, ID | Sort ProcessName | FL

7. o PowerShell scripts differ from most scripts o PowerShell scripts end in.ps1 and have to be run inside a PowerShell window o Double clicking a PowerShell script will open the script in notepad o Scripts must also be run in this format

8. o Restricted – No scripts can be run. Windows PowerShell can be used only in interactive mode. o AllSigned – Only scripts signed by a trusted publisher can be run. o RemoteSigned – Downloaded scripts must be signed by a trusted publisher before they can be run. o Unrestricted – No restrictions; all Windows PowerShell scripts can be run.

9. o PowerShell can tap in to the WMI classes of another computer as well your own, given you are using administrative credentials o Ex. Get-WmiObject Win32_Product will list all of the Microsoft installed products on your machine (products installed by Windows Installer)

10. o You can use the runas command in the ‘start’ menu to run the PowerShell console as administrator o There is a Cmdlet called Get-Credential which can store administrative credentials in a variable o Can’t be used to authenticate to local machine

11. o Because WMI calls utilize the RPC protocol, the Windows Firewall must be turned off or Remote Administration must be enabled o The RPC protocol uses random ports

12. o Pull computer serial number o Gwmi Win32_Bios | select SerialNumber o Reboot a machine o (Gwmi win32_OperatingSystem –comp | server).reboot() o Gather Logical Disk Space information o Gwmi Win32_LogicalDisk o Show running processes o Gwmi Win32_Process

13. o Variables are defined by the two following ways [type] $variable = x or just $variable = x o To display a variable you would just type $variable o Ex. To store the installed products on your machine o $Product = gwmi Win32_Product

14. o If you displayed the contents of $Product, it would display the entire list of products that it pulled o To individually go through each installed product you would need to use a ForEach statement

15. o Server 2008 R2 o Window 7 o Exchange 2007/2010 o System Center 2008 Suite o SQL 2008/2008 R2 o SharePoint 2010

16. o www.scriptinganswers.com www.scriptinganswers.com o www.primalscript.com www.primalscript.com o www.scriptingoutpost.com www.scriptingoutpost.com o http://www.microsoft.com/technet/scriptcente r/topics/winpsh/convert/default.mspx http://www.microsoft.com/technet/scriptcente r/topics/winpsh/convert/default.mspx o Site Converts VB code to PowerShell Code

17. o $NIC = Get-WMIObject Win32_NetworkAdapterConfiguration | where{$_.IPEnabled -eq "TRUE“} o $NIC.EnableStatic("192.168.100.66", "255.255.255.0") o $NIC.SetGateways("192.168.100.1") o $NIC.SetDNSServerSearchOrder(“8.8.8.8”, “8.8.4.4”) o $NIC.SetDynamicDNSRegistration("FALSE")

18. o Gwmi win32_process | select name | sort name o (Gwmi win32_process | where {$_.name – (match “processname.exe”}).terminate(1)

19. o gwmi win32_terminalservicesetting -comp computername).setallowtsconnections(1)
