I can't get my WMI light to work anymore. This is on 3 different systems. It used to work. These are paid versions so the capability is there. I've reset the phones to factory status and it works for a little bit or not at all, or stays on and never shuts off. On an XP box it works fine. These are all on Server 2003 or Small Business Server 2003. Anyone else have these phones and this issue?
