Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
References
See the terminology that Microsoft uses to describe software updates.
More Information
This issue occurs in the following scenario:
-
The site-to-site VPN connection is disconnected.
-
Before the disconnection is completed, a new connection is initiated by the traffic.
Because the RRAS server may hit a race condition, the routing table will end up in an inconsistent state, and TCP/IP will drop the incoming packets.
