Add Windows Features to Remote Servers

This morning I had a question come in on LinkedIn about installing the SNMP service on 20 remote servers. The first person who responded recommended using Enable-PSRemoting on all servers and the downloading some tools from Sysinternals. He was on the right track. The problem is that process would require either traveling to the remote sites or providing admin credentials to local users to do it for him. Also, the full power of PowerShell remoting is not utilized since the instructions were to utilized other software.

A simpler solution would be to enable PowerShell Remoting via Group Policy :(http://mctexpert.blogspot.com/2011/03/enable-powershell-v2-remote-management.html).

Next, you need to create a session to your remote servers.

$Session = New-PSSession –ComputerName SVR1, SVR2, SVR3

Using the Invoke-Command cmdlet, you can execute commands on the remote machines. You first need to import ServerManager on the remote machines (Unless your remote servers run PowerShell V3) and then add the feature. This importing of ServerManager is actually being done on the remote servers. Look carefully, that is a semi colon “;” after ServerManager.

Invoke-Command –Scriptblock {Import-Module ServerManager; Add-WindowsFeature “SNMP-Services” –IncludeAllSubFeatures} –Session $Session

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.
