Lab 7: Advanced PowerShell for System Administration

Objectives

Learn to manage Windows 7 systems with advanced PowerShell (PS) features.

Resources:

You can find information in these web resources to help you complete the tasks below

// using windows powershell for administration

// enable remote commands

// remoting in powershell

// invoke-command

Procedures

Please work on this lab with a partner as a team of two. Perform remote execution on each other’s machine.

Part 1 – Remote Execution

Setup your (you and your partner) machines to remotely execute your WMI PS script from Lab 6 on each other’s machine. The resources listed above can be helpful.

Notes:

-You need to enable remote PS, the “winrm” service.

-You need to add each other’s computer as trusted connection.

-You may (or may not) have to modify your script.

-You may (or may not) have to create a remote PS session.

Part 2 – Remote Administration

Use PowerShell to manage remote computers by specifying -ComputerName parameter. Learn to use pipes and filters.

Write PS scripts to do the following tasks:

  1. List all the hot fixes installed on a remote machine that are “Security Update”.
  2. From a list of at least two machines (IP addresses or machine names), find out if hot fix KB2620712 is installed on each of the machines.
  3. For a remote machine, list the MAC addresses and description for all the DHCP enabled adapters.
  4. For a list of at least two machines, renew DHCP lease for all DHCP enabled adapters on each of the machines.
  5. For a list of at least two machines, ping them every 10 seconds and give a message if any of them fails to respond. You can simulate this by disable the network adapter or unplug the cable on the remote machine.

Here are some sample PS scripts that might be helpful for you to get started with your tasks. Try them with a remote machine name (replace “.” with a valid IP address or machine name) and see what they do.

Pass-off

Show both part 1 and part 2 to TA or instructor.
