What I mean is that we had AFS working on 192.168.130.0/24 and our  
corporate network is on 192.168.128.0/23.  The corp network needs to  
grow, so we are changing it to 192.168.128.0/22 (this is where are  
our issue starts) 130 will end up being included in 192.168.128.0/22 
(which is not what we want for other reasons).

So when I said IPScope I'm mixing up subnetting and windows DHCP GUI  
interface terminology(eek sorry).

My understanding was that if the vldb server are so out of whack, 
(because of something I've done) why not kill what they know and then  
get all the correct info from the fileservers.  Which seems like it  
would be the quickest fix.

Does the db directory on the AFSDB's only contain volume info?
