DNS not pushing to PDC

Have two domain controllers, Window Server 2003 R2 with DNS also installed. I can create a new record on the PDC, and check the other DC and the DNS record shows up. However if I delete it at the other DC and increment the SOA number, it does not push to the PDC. It sticks around.

I ran DCDIAG /TEST:DNS and all passed.

The DNS updates between domain controllers are synchronized as part of the AD synchronization and not as DNS push/pull. It is normal to have up to 15 minutes delay.

thanks. I checked a while longer and it was gone. that's good news.

what is the difference between reload and refresh? when is one better or detrimental to run compared to the other?

Reload reloads the full DNS tables from the Primary DNS while Refresh checks for updates only.

However, they don’t have an effect on AD-Integrated zones.

If you have Primary/Secondary zones, you could use each of them to update the secondary zone. But if your zones are huge, Reload could take quite a long time.
