Dns server is not updating
It might be easier to drop your scope lease time really low, then delete all the dynamic DNS records and let them get re-created.
If you're waiting on DNS scavenging, there's no fast way to do it.
The actual time of propagation may vary in some locations based on your network setup.
When you make a DNS change, it takes time for the changes to take effect. It is the time it takes for the domain DNS to refresh the cache on the network.
The cache is cleared over a certain amount of time.
We suggest waiting up to 24 hours for the DNS cache to be fully refreshed. When the DNS refreshes according to its TTL, the propagation is complete and your site will load.
I created my reverse zone and added a forward zone bigorange.local - when I add computers to my domain, DNS is not updated with their IP address and hostname.
When you do an 'nslookup' on the SOA does it give the right answer?
Changing the timeouts is only going to help clients the next time they check in, which is usually after half the existing lease time, or sometimes during boot.
You can approach this by manually forcing the clients to check in.
When a domain is newly registered, the nameservers are changed, or DNS changes are made, you can expect a propagation time up to 24 hours.
This is because it takes time for the DNS to take effect across the internet.
