SSTP: Microsoft new VPN tunnel using SSL is coming
Microsoft's RRAS team is very happy to announce that SSTP will be first time released to all our TAP and techbeta customers via Vista SP1 beta and Windows Server 2008 RC0 release which was released on Sept 25th, 2007
To get your hands dirty with SSTP, work with your Microsoft TAP contact if you are part of Windows TAP program. If not, you can be a part of Windows techbeta program via enrolling to http://connect.microsoft.com and get the Windows beta bits.
To do a SSTP pilot or lab deployment, all you need is:
1) A machine running Vista SP1 beta or Windows server 2008 RC0 or later - acting as VPN client
2) A machine running Windows server 2008 RC0 or later - acting as VPN server
Please enroll and get your set-up ready.
