I'm not aware of a dedicated utility.  However, the KDC is basically a 
stateless UDP service, so recording a live transaction and replaying an 
input packet is expected to yield some sort of response packet.  Doing 
this periodically allows for a very primitive "liveness check" which can 
be used in some monitoring setups.  Of course, if one wants to monitor 
that the KDC is actually functioning properly and not just spewing error 
packets, more effort is required.
