spc> Has anyone else been seeing a dramatic increase in /scripts/.. NT worm

Yes. We are seeing it here bigtime.  Does anyone have any apache hacks
to lessen the impact?  One idea:  Once a probe is sent, the prober's
IP# is stored in a hash (perhaps in shared memory or a mmap'd file
that all children can share) and new connections from that IP are no
longer accepted.
