Duplicate DNS A record issue

[justin koestler]

We are running active directory with Cisco Network Registrar DNS and
DHCP. I will start with an example since its the easiest way to
explain this issue. A user, lets call him Bob, has an old computer
that is named "BOB" on the network. Bob needs to get his computer
upgraded to a more powerful computer. The help desk then switches
Bobs computer out for a new one, when the old one is offline, the new
computer is turned on and configred with the name "BOB". Our problem
is that DNS/DHCP has not updated the record for BOB, it has instead
created a new record named BOB-1. This is ofcourse breaking kerberos
within active directory since machine authentication fails since Bobs
desktop is really not named BOB-1. I know that DNS/DHCP is doing this
because it thinks there is a duplicate named machine on the network by
seeing a new MAC address for a record that already exists. I would
like DNS/DHCP to update the record with the new MAC address, not
create a new record.

Is this something I need to fix on the workstation side or is this a
configuration problen on our DNS/DHCP servers.

any help would be great.

Thanks

I am unfamiliar with "Cisco Network Registrar DNS and DHCP", but Windows DNS
and DHCP do not do what you are describing.
