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

Error icon when creating a GPO Preference drive map

You may not have an error at all. Take a look at the drive mapping below. The red triangle is what threw us off. It is not an error. It is simply a color representation of the Replace option of the Action field in the properties of the drive mappings. Create action This give you a green triangle. The Create action creates a new mapped drive for users. Replace Action The Replace action gives you a red triangle. This action will delete and recreate mapped drives for users. The net result of the Replace action is to overwrite all existing settings associated with the mapped drive. If the drive mapping does not exist, then the Replace action creates a new drive mapping.
