How can I remove a dead zone?

Problem: Non-existing zone keeps re-appearing on ethernet phase 2.

Scenario: Phase 2 ethernet with 11 Kinetics and Shiva FastPath 4's,
all of which are configured with K-STAR. They, of course, each
define a single appletalk zone with a unique netnumber on
their appletalk side.
One of the FP4's is seeding the others with respect to ethertalk 2;
it has a range of ethernet numbers from 2 to 2 (i.e. only one number)
and it knows about only one ethernet zone - let's call it ZONE A. 
All other FP4's have range 0 to 0 and no ethernet zones.
There is only one Mac II connected directly to the net with
an Apple EtherTalk card and running ethertalk phase 2. When I installed
ethertalk on this Mac, I assigned it to ZONE A.
The ethernet also contains a 3Com server with appletalk and
several Unix mainframes (without CAP, atalkad, etc.)

History: The seeding FP4 was originally configured with two
zones, ZONE A and ZONE B and a netnumber range of 2 - 12. It
worked like that for some weeks, and then I re-configured it
to only ZONE A and netnumber 2 - 2.

Question: why does ZONE B still appear in the chooser? 
And why do some of the FP4's give the following complaint:
"Conflicting inf.: local range=2-2; 2-12 reported on ETALK2"?
I have tried to zap the pram of my Mac II and re-install ethertalk 2.
Just after re-installing ethertalk my Mac only knew about ZONE A 
- but a few minutes later ZONE B re-appeared from the grave. 
It scares me a little! How can I make it go away for good?

PS: It's not practical to turn off all 11 FP4's at the same
time, as someone might suggest. They are distributed all over
campus.
