Windows SNMP Service missing tabs

If you’re trying to configure SNMP on a server from a remote workstation, make sure you have SNMP installed on the remote workstation or you’ll miss the Agent, Traps, and Security tab on the SNMP service properties.

Thanks to thomasmaurer.ch for getting me on the right track.

w/o SNMP installed on the remote workstation you can’t fully manage SNMP remotely.

Powershell and SNMP

I’ve been trying to get all my servers snmp settings fixed and it’s been kind of a pain. Powershell doesn’t have any good cmdlets, but I’ve found a couple examples. This is very nice script, but doesn’t work on remote machines unless you do PS Remoting. (I need to bone up on my PS remoting now.)

I ended up using the following for the base of a script. I need only a very simple script so this looks for a specific registry key which will be the name of the CommunityString. Since mine is ‘Public’, I’m just looking for that.

function Get-RemoteRegistryValue ([string]$ComputerName, [string]$KeyPath, [string]$Value) {
    try {
        $Hive = [Microsoft.Win32.RegistryHive]::LocalMachine
        $reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($Hive, $ComputerName)
        $key = $reg.OpenSubKey($KeyPath)
    } catch {
        return "ERR"
    }
    return $key.GetValue($Value)
}
Get-RemoteRegistryValue -ComputerName $server -KeyPath 'SYSTEM\CurrentControlSet\Services\SNMP\Parameters\ValidCommunities' -Value 'Public'
