remove a unused synchronisation address from a unmanaged replica

how can i remove a unused synchronisation address from a unmanaged replica
?

see my last post ( 5/29/08 )

i moved design masters from 1 server to another and now i want to phase
out 
the old server, but all of the unmanaged replica's now hold both
addresses.
( the new server now holds the design master and the old server is 
synchronised and is now a replica )
if i shut down the old server, synchronisation with the new server fails.

i tried "remove defunct replica", no luck. somehow the replica still wants

to synchronize with the old server when i choose the new server address.
