So to recap, some problem solving tools worth knowing are:
1. desk-check, actually read, and 'trust but verify'
talking through a problem often does this, because it
forces statement of assumptions that may not actually be true,
as in Stephen's case. My suspicion of VLAN network
partitioning just pointed out a place to look closely
2. 'simplify, simplity'
3. binary partition
