Add feature using powershell to server 2008r2

Try below.

This does not use powershell but it uses batch file and PSExec.

Hi David, many thanks. How do I target the script at a remote server?

If you only need to do this once, I would suggest using the SNMP Enabler from Solarwinds.

http://www.solarwinds.com/products/freetools/snmp-enabler-for-windows/enable-snmp.aspx

It is a free tool and worked wonders when I enabled SNMP on our systems.

Thank you for the info David - much appreciated.

Can I just check that I have this correct. The script will add the SNMP feature on the target machine and not cause an issue if the feature was already enabled. Will it then go on to populate the SNMP community within the SNMP service too?

Hi Jason,

Just a note the name of the service is SNMP-Service and not SNMP-Services so you will have to remove the last s character from the name of the service, if you don´t do this you will be presented with an error.

"The script will add the SNMP feature on the target machine ".
Yes, this piece of code will check if the service is installed or not, if not the service will be installed.

#Check If SNMP Services Are Already Installed
$check = Get-WindowsFeature | Where-Object {$_.Name -eq "SNMP-Service"}
If ($check.Installed -ne "True") {
	#Install/Enable SNMP Services
	Add-WindowsFeature SNMP-Service | Out-Null
}

Select allOpen in new window

 "if the feature was already enabled"

This is checked by this piece of code, if the service is not enabled and not configured this will be configured.
But if the service is already enabled and configured, the settings will be override on the Reg Keys. So be carefully.

##Verify Windows Services Are Enabled
If ($check.Installed -eq "True"){
	#Set SNMP Permitted Manager(s) ** WARNING : This will over write current settings **
	reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SNMP\Parameters\PermittedManagers" /v 1 /t REG_SZ /d localhost /f | Out-Null
	#Used as counter for incremting permitted managers
	$i = 2
	Foreach ($manager in $pmanagers){
		reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SNMP\Parameters\PermittedManagers" /v $i /t REG_SZ /d $manager /f | Out-Null
		$i++
		}
	#Set SNMP Community String(s)- *Read Only*
	Foreach ( $string in $commstring){
		reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SNMP\Parameters\ValidCommunities" /v $string /t REG_DWORD /d 4 /f | Out-Null
		}
}
Else {Write-Host "Error: SNMP Services Not Installed"}

Select allOpen in new window

I hope this will be what you want.

Regards

Many thanks
