No SSTP in XP SP3
The mixed reports that I’ve read up to this point didn’t really nail down whether or not SSTP as a VPN protocol was going to be included in SP3. Last night I updated one of my machines to SP3 and confirmed it is not present. That’s a bummer. That’s an incredibly useful protocol and would have been extremely handy to backport to XP, but instead it’s still only supported for Vista or Server 2008 clients. Lame. I’m sure Microsoft didn’t want to give anyone more reason not to upgrade to Vista.
