SSTP VPN to Server 2012 R2 High CPU

[ITGURU]

Hi

I regularly connect to our network via SSTP VPN using the routing and remote access capability of Windows Server 2012 R2.

I notice that when i am connected, CPU spikes as shown below, but jumps upto around 35% - it's always constant - it doesn't come and go.

 

 

As soon as I disconnect the connection, the service drops off complete back to CPU idling only.

 

Anyone else noticed this, or know what could be causing it? It happens even when just connected, and don't have anything open across the connection.

 

Tried from multiple computers both on Windows 8.

 

Thanks.
