Event ID 9 — RRAS Secure Socket Tunneling Protocol
Applies To: Windows Server 2008 R2
Secure Socket Tunneling Protocol (SSTP) is a new form of virtual private networking (VPN) tunnel with features that allow traffic to pass through firewalls that block PPTP and L2TP/IPsec traffic. SSTP provides a mechanism to encapsulate Point-to-Point (PPP) traffic over the Secure Sockets Layer (SSL) channel of the HTTPS protocol. The use of HTTPS means traffic will flow through TCP port 443, a port commonly used for Web access.

|Message:||The Secure Socket Tunneling Protocol service could not secure the URL with the new service configuration. Other applications or services can override the URL reservation. Use 'netsh.exe http add urlacl' command to secure the access control list (ACL) manually. The detailed error message is given at the end of this message.
Set permissions for the specified URL for SSTPSVC
Namespace reservation assigns the rights for a portion of the HTTP URL namespace to a particular group of users. A reservation gives those users the right to create services that listen on that portion of the namespace. Reservations are URL prefixes, meaning that the reservation covers all subpaths of the reservation path.
Use the netsh http add urlacl command to configure access control lists (ACLs) for the URL for SSTPSVC use.
The following is an example of how to use this command:
netsh http add urlacl url=http://+:80/MyUri user=DOMAIN\user
