Network security map still crashing

Pretty annoying, really.  Once the computer boots up its hit or miss as to whether or not I can immediately remote desktop into it.  Despite being in a full trust network sometimes it takes several minutes or more before I can remote desktop into the machine once it has booted up.
Second problem is that NIS crashes almost every time I go into the Network Security Map to have a look.  This is a brand new Windows 8.1 box fully patched, with a fresh NIS install.  Mini DMP attached.  It looks like you guys are corrupting a heap table in what looks to be SymHTMDX fileversion 8.00.0.58

I tried posting a stack trace but after spending 20mins trying to tweak it and getting "your submission contains invalid characters and will not be accepted" I gave up.  The stack is in the DMP.
