I have an issue where I am getting the following error being displayed on my
NetWare 6.5 SP3 DNS server console.

The error is:
"Error: client #4001: update '13.16.172.IN-ADDR.ARPA\IN'

I have DHCP with Dynamic DNS update enabled and this address is part of the
DHCP range. Is this something to do with that configuration and how can I
address this error?

Many thanks,
