SYSTEM_SERVICE_EXCEPTION (3b)

My 2012 R2 terminal server has been crashing every once in a while. I've tried to go through the dump files but I'm not good at reading them to get to the root cause. Thought I could get some help here at understanding them so I can find a solution to this problem. Here is the dump log.

    There's really nothing to be learned here.  You're getting a null
    pointer dereference inside the Asynchronous Local Procedure Call
    subsystem.  About all you can do is open a support incident with
    Microsoft technical support, and hope your dump reaches the proper hands.

    Your going to have to dig deeper into this dump or likely capture a full
    memory dump. What I'm interested in is that this process is werfault.exe so
    I'd like to see the peb block to see what process its attaching too and
    then see why what that process was doing. [!peb]

    I'm not sure why werfault.exe is generating an SYSTEM_SERVICE_EXCEPTION
    but maybe it's down to the process it's attaching to. I guess a non
    windbg diagnosis avenue is to see if there is anything about app crashes in
    the eventlog.

    Kind Regards,
    Tom
