DNS - Issues

[jreimer]

Got a crazy one which someone might understand.

I have a DNS server which gets updates the Host A records from DHCP in the foward lookup zone, but in the reverse lookup zone I have the same IP with a different name. When i go to ping the IP I get no reply so it is not there like the foward DNS says. So why the erronous reverse lookup.

I have scavening on and it equals my 8 day lease through DHCP

Thanks for any help

Wipe the reverse look up zone's contents and then do a dhcp release/renew and see if "new" records are created correctly.

I'd have thought scavenging would have helped mind you, but I have seen cases where forward is OK but backwards is erroneous.

Have you tried manually removing it.

I don't have a (Windows) DNS server to hand, but I though (perhaps incorrectly) that the reverse lookups where configured manually.

Are the DHCP duration settings the same?

Is scavenging turned on at the server and zone level?
