Symptoms
Consider the following scenario:
-
You install the Network Policy and Access Services server role on a server that is running Windows Server 2008 or Windows Server 2008 R2. The Routing and Remote Access service is running on this server.
-
You configure the server to accept one or more of the following connections:
-
Point-to-Point Tunneling Protocol (PPTP)
-
Layer 2 Tunneling Protocol (L2TP)
-
Secure Socket Tunneling Protocol (SSTP)
-
-
Several clients connect to the server concurrently.
In this scenario, the Routing and Remote Access service (RRAS) may crash. When this service crashes, all existing virtual private network (VPN) connections are terminated and no new VPN connections can be established. You have to manually restart the server to recover from the issue.
Cause
This problem is caused by a timing issue in the Route Table Manager (iprtrmgr.dll) of the RRAS. When the timing issue occurs, the RRAS accesses a freed memory space. This behavior triggers an access violation exception that crashes the RRAS.
