DNS record update

I have 6 DCs, 2 in each site(in each subnet in the LAN) they are all DNS ADIntegrated zone.
I have a computer that is joined to the domain and belongs to site1(subnet1), I have renamed the computer, but only the DNS servers in site1(subnet1) that have updates its record.

the other DNS servers in other sites(other subnets) haven’t updated the record.

It’s been 8 hours since I renamed the computer.

any idea ?

Thanks

Since the zone is AD-integrated, its data is replicated among the servers as part of AD replication. Do you have intersite AD replication set to occur only during a certain time interval (after business hours, for example), or can it occur at any time of day? If it can occur at any time, you may want to make sure you don’t have something preventing replication from taking place. AD Sites and Services would be the first place to check, along with the event logs of your DCs.

That all seems pretty reasonable. Are all of those replicating properly? Errors will be reported in the Directory Service log.
