OSD Code 28
If you are attempting to use a VPN connection and your Sun Ray gets stuck at OSD Icon 28 (trailing letter matters not), it could be due to the fact that there are switches set up to filter
IPsec/IKE traffic (ports 500 and possibly 4500) and the first IKE message is not getting through to the VPN
gateway. Just a little nugget I learned today (from a non-blogging guru) and am passing it on to you. Good to know the cause because this happened to me last week in Cincinnati and cut my demo short. Update: Non-blogging guru clears up a couple of my ASSumptions.
