NetInfo problem (server thinks it's a clone)

I have had a Netinfo problem in which I seem to have reconfigured my server so  
that it thought it was a clone server.  I *believe* I have fixed this, but  
since I'm no Netinfo expert I'd like someone to tell me if I've done this  
right!

I'm running NeXTSTEP 2.1 (will do the 3.0 upgrade after resolving this issue).   
I have two NeXTs: sailfish (the domain server I screwed up) and catfish (which  
is served by sailfish).  I thought I had backups of /etc/netinfo but.... (Now I  
do and will continue to do so.)

A couple of weekends ago we had a campus-wide IP address reconfiguration. I  
needed to change the gateway IP address, the broadcast mask, etc.  Apparently I  
should have physically disconnected my host 'sailfish' from the network before  
doing this, because the next time it booted, I got the error message that it  
couldn't find its parent Netinfo server.  (It *is* the Netinfo server for my  
two-machine network, at least it's supposed to be.)  I deduced it now thought  
it was a clone server.

After glancing at Chapter 8 in the Network and System Admin. manual that came  
with NeXTSTEP 2.1, I made some educated guesses about how to fix this.  In the  
domain I had access to when the machine booted (now /sailfish), I opened the  
subdirectory /machines and removed the 'serves' property from broadcasthost,  
then added a new machine 'sailfish' with the right IP address and the value  
'../network' for the 'serves' property.  So now, instead of the two that were  
there, there are now these 3 entries in /sailfish/machines:

   name: broadcasthost
   ip_address: 255.255.255.255
   
   name: localhost
   ip_address: 127.0.0.1
   serves: ./local
   
   name: sailfish
   ip_address: 131.91.80.15
   serves: ../network

The machine now boots fine (at least so far) and NetInfo does come up with my  
network as it did before I created this problem.  If I open the highest level  
domain, I do find sailfish listed in /machines as follows:

   name: sailfish
   ip_address: 131.91.80.15
   serves:  sailfish/local ./network

This looks ok to me (I guess).

Could someone confirm that this is what I should have done, or make some other  
suggestions?  As I said, I'm not a netinfo expert.  My immediate goal was to  
get this fixed (at least temporarily) so I get my classes' final grades  
compiled!  Now I want to make sure it's fixed right.

Thanks in advance for any help!
Tom
