ValidateResourceProperties always finds DhcpOption

[gordonbondon]

This

$dhcpOption = Get-DhcpServerv4OptionValue -ScopeID $ScopeID

never returns empty. According to technet article if not specified default Lease Duration for a scope will be 8 days.

Because of this Option 51 Lease Duration is always present in new scopes and ValidateResourceProperties always finds DHCP option so this part of code is never reached.

And this is called when it should not be called and as a side effect removes Lease Duration option and sets lease time to 0:0:0.

foreach($option in $dhcpOption.OptionID)
{
    Remove-DhcpServerv4OptionValue -ScopeId $ScopeID -OptionId $option
}

I've tested this behavior on freshly deployed 2012 R2 with lates xDhcpServer from PSGallery.
