Hello,
Our main DNS server is running on windows server 2003. We have duplicated entries, what I discovered when trying to nslookup an IP address and always getting in return wrong computer name, except for fixed IP addresses.
To solve this, first, I configured DHCP to become the owner of records and enabled it to perform dynamic updates on behalf of clients by following this excellent how-to:

Then, I enabled scavenging but it seems to be a very slow process. In my case, it will launch after 168 hours = 7 days, what I can see into the event logs when I look after 2501 and 2502 events.
Is there a way to clean up all that crap faster? Also, we have speed issues with crm outlook plugin for Dynamics: working with CRM directly into Outlook can be quite slow. Do you think that it could be linked to all that mess we have into our DNS server?
Last point: we have a secondary DNS server running on windows server 2008 R2. Is there something to configure also on this one, or, as I already performed tasks explained above on our main DNS server, there is nothing more to do and the secondary DNS server will passively follow the primary DNS server.
Thank you!
